Factory Layout – What are the Options

November 23, 2022

In my previous post we covered what to consider for factory location. Having selected a location in which to set up a factory, the next question is how to lay it out.

Factory layout refers to the arrangement of physical facilities so as to have the quickest flow at the lowest cost and with the least amount of handling in processing from the receipt of material to the dispatch of the finished product. The aim is to allocate and arrange space and equipment to minimise operating costs.

As with location selection, factory layout is a long-term commitment. To optimise the relationship between output, floor area and manufacturing process, an efficient layout must achieve multiple objectives simultaneously:

The proper and efficient use of the available floor space
Work should proceed from one point to the next without delay
Adequate production capacity and flexibility, including potential to expand, at least in the short- to medium term
Lower material handling costs
Employee health, safety, accident and injury prevention
Efficient labour and equipment utilization and productivity
Maintaining quality standards, managing waste and storing inventory
Ease of supervision, and control
Plant and equipment maintenance
Complying with local regulations

Factory Layout Options

There is no one-size-fits-all option. Each factory, location and industry is unique, though the basic principles remain the same.

For small and medium manufacturing units, there are three main layout options, for which the main pros and cons are laid out below:

Product (Line) Layout

Equipment is arranged in a single line determined by the sequence of operations in this layout. Advantages are that it is low cost, operations are smooth and have continuity. The production control process is also simpler. However, the layout lacks flexibility. One process breakdown can bring the whole factory to a halt.

This layout is best suited for mass production where the process is repetitive, demand is stable and material availability is reliable.

Podrain expects to use this design for our larger ‘volume production’ factory.

Process Layout

Sub-process equipment and staff are grouped together in this layout. This is flexible and adapts fast to changes in volume and product variety. It’s also possible to ensure specialised supervision where needed and ensure high utilisation. However, more skilled labour is needed and production controls need to be strong to avoid time lags and inventory accumulation.

This layout is best suited for non-standard product lines, smaller quantities and where frequent changes to design may be needed. Podrain currently uses this layout in its prototype and small batch manufacturing facility.

Combined Layout

This blends the product layout and process layout where some steps of production are laid out by product line and others have sub process equipment and staff grouped together. this is a very complicated layout to design. When done right, it can offer efficiency and better production controls. However even a small error can lead to being stuck with bottlenecks in the production process. It’s typically used in very large manufacturing organisations for FMCG items.

Single-Storey vs. Multi-Storey Factory

Land is scarce, and suitable land is scarcer still. So, having selected a location and figured out the plant layout, one is left with the decision of a single-storey versus a multi-storey building.

Single-Storey Building -Advantages:

Greater floor loads, no structural strength needed to support upper storeys
Lower noise transmission and building vibration
Ease and lower costs of building and expansion
Natural light and ventilation
Higher floor area usable for processing – no stairwells, lifts, shafts, etc.
Concentration of service facilities centrally yields lower operating costs
More efficient layout and material handling, product routing
Lower cost of supervision

Multi-Storey Building – Advantages:

More efficient utilization of land area, and smaller land area requirements
Temperature management costs are significantly lower
Greater structural strength, higher construction quality, fireproof and longer-lasting
Upper storeys dust-free, especially for precision manufacturing operations
Downward chutes are cost-effective for material movement
Compact, more efficient layouts – though there is a limit to the benefit of this

Whether single- or multi-storey factories are more economical to build and operate per square foot of usable floor space is hard to determine. Local and regional considerations regarding regulations and land prices may play a significant role and costs may vary over the course of time. For example, our Bangalore factory is a multi-storey facility. While production control is a little more difficult, land availability at a central location in the city is a key factor in our choice.

In conclusion, siting, designing and building a plant that’s conducive to business success is all about balancing the trade-offs between costs, time, complexity and benefits in pursuit of the goals of the company.

In PCB manufacturing, repeatability and consistent quality are critical – whether for large-scale production, small batches or prototypes.

Skilled and experienced technicians can and do create excellent work, but relying on individuals to establish, deliver and sustain top-quality results is risky. Programming Automatic Inspection Machines and processes is expensive, time-consuming and not always practicable, especially when prototyping.

Testing

Prototype QC needs to ensure that the design will work; that it is safe, and meets certain standards of quality and reliability; that it performs to expectations; and that it addresses its purpose.

Small batch PCBs have some rather unique attributes:

High Mix, Low Volume (HMLV). It’s likely that the PCB manufacturer builds several board designs in this environment to ensure efficient use of their production infrastructure.
Higher performance, reliability and quality requirements. Small batch and prototype PCBs are often intended for critical applications where more stringent IPC standards apply, like aerospace, automotive safety or medical devices. Quality and reliability expectations can be significantly higher for these critical system applications.
Complex designs. Prototypes are created to solve specialized and often complicated challenges, which means their designs are complex, requiring atypical manufacturing processes

How to ensure the best quality standards for prototypes and small batches

In-circuit testing (ICT). Provides a reliable, high-fault coverage verification method for the majority of PCB assembly electronic components that’s free of human error. It’s great for big assemblies or ball grid arrays and after assembly.
Short circuit testing. The main cause of PCB prototype defects is a short circuit between its larger components. For example, a fastener between two proximate pins can damage the microcontroller by triggering a short. It is vital to gauge the impedance each voltage node to the ground. Faulty components or incorrect soldering can cause components to overheat.
Flying probe test. A practical, cost-effective technique for prototypes and small batches that tests PCB probes from one spot to another, looking for singular issues in the circuit – shorts, capacitance, resistance, inductance, opens and problems with diodes.
x-ray inspection. As the prototype is being manufactured, an x-ray technician runs tests to locate defects, looking for elements that may be hard to discern with the naked eye – for example, joined connections, internal traces or barrels.
Functional testing. The #1 criterion for a prototype’s success is, “Does it work?” Performing a functional test requires the parameters for ‘success’ to be clearly defined. Functional testing takes a long time, because it simulates the real-life environment in which the prototype is expected to work. But in terms of long-term value, it’s worth doing. A great deal of money and time can be saved by identifying potential operational pitfalls and eliminating them at the design stage.
Burn-in testing. Intended to identify failures early and initiate load capacity. Burn-in testing helps identify potential dangers relating to power being pushed through the electronic components for extended periods of time. One must keep in mind that individual prototypes may be partially or even completely damaged by a rigorous burn-in test, and the test’s utility to prototype QC should be decided based on the destination application of the PCB.
Automated optical inspection testing (AOI). Camera-based visual inspection to identify issues that may emerge on the board during the preliminary phase of assembly. It’s wisest not to rely entirely on AOI, but to complement it with an ICT or flying probe for more accurate QC results.
Inverted polarity testing. The more manual assembly, the higher the risk of human error. The simple act of ensuring that each individual component is set up based on its polarity can prevent the complex and delicate components of your prototype being badly damaged. Protection diodes can protect PCBs but add to their power consumed.
Populated components testing. A simple BOM cross-check to ensure that the components selected fit the board design can save investigative time and effort later in the process.

Several other QC approaches, including tests for PCB contamination, solderability and peeling; micro-sectioning analysis; and time-domain reflectometers, can identify faults or be used in combination with those discussed above, like ICTs and flying probes.

Choose the right QC test(s) for your prototype

It begins with clearly defining the purpose and desired performance levels of the PCB; weighing the pros and cons of the available tests – which include costs, time required, destructive vs. non-destructive; and always keeping in mind, especially when prototyping, that the design-test loop can flex and adapt as the product design is iteratively perfected.

It’s always a good idea to partner with a manufacturer who is committed to the best quality; has documented and traceable processes; has the necessary quality and classification standard certifications; is experienced at HMLV manufacturing; and leverages technology to ensure high-quality, repeatable results.

Podrain collaborates closely with its clients when prototyping and producing small batches, and meets the highest quality and classification standards. We advise clients on the right mix of testing to ensure that their prototype PCBs meet the final test of quality – sustained, reliable, top-level performance in the field.

Why we need to Near Source Electronic Components

The past two years have offered some harsh lessons to all in the PCBA industry on the value of inputs. For a long time, the cost paid was the only consideration. The supplier might be located on the other side of the world, but if the cost was marginally lower, the choice was clear. But the pandemic changed all that. The cost of logistics / transport that used to be negligible ballooned beyond expectations. And for some parts – no matter what cost we were willing to pay – the availability just did not exist.

PCB Assembly

In India, we import more than 90 percent of the components required for assembling PCBs locally. These imports come from 4 countries – China, Taiwan, Vietnam, and Malaysia. A break down at one source country, as we saw in 2020 and 2021, drives up the cost of doing business for all.

Here’s our experience with supply trends for some of our major inputs:

Bare PCBs:

Bare PCBs are the stronger point in our supply chain. We have seen reliable suppliers of Bare PCBs based in Tamil Nadu and in Gujarat. We (and many of our customers) have been able to source Bare PCBs in the past 18 months with no major issues. Supply lead times have remained consistent and price increases have stayed within tolerable limits.

Assembly Machinery:

Machinery needed for PCBA is mostly manufactured outside India by majors like Yamaha, Fuji, Panasonic, and Siemens. While prices have stayed stable, lead times have increased considerably. What used to be available in 4 weeks now takes 4 months to get delivered. We’ve had to plan and order earlier than ever before for any capacity enhancements or repairs and replacements.

Other Components / Services:

Integrated Circuits (IC’s), their component resistors, capacitors et al, solder paste etc. are mostly imported and have all seen prices and lead times zoom up. 52 weeks is now the new normal! Companies like Micron, TI, Cypress, Infineon, Latis, NXP have factories based in China, Taiwan, Malaysia, and Indonesia. When supply and manufacturing centers were shut and major ports slowed down, component shortages have visibly hit every industry from automotive to computers and mobile phones. Even stocks held by major distributors Avnet, Future, Arrow, or online suppliers like Digikey, and Mouser could not tide the industry over for long.

This is the area where India needs to attract investment and build manufacturing capacity.

What Next:

The government has already recognised the need for building an electronics components manufacturing ecosystem. It is doing its part by offering Production Linked Incentive programs and other sops to encourage manufacture of components in India. It is now up to us in Industry to pick up the challenge and partner in building a strong local eco-system for components.

India’s Aerospace and Defence (A&D) market is estimated to grow to around $70 billion by 2030 with government encouragement and improving infrastructure. There are opportunities beyond commercial and military aviation. Private players are entering new areas like unmanned flight, space transportation and commercial satellites.

When most people think of India and space, they see VSSC and ISRO. In recent years, several impressive private startups have entered the domain. These startups are driven by strong R&D, and they are changing the profile and perception of Indian high-tech. Here are just a few:

Asteria Aerospace combines robotics and AI to create customised hardware products and software solutions for UAVs.
Bellatrix Aerospace, incubated at IISc, develops in-space propulsion systems and orbital launch vehicles.
Agnikul was incubated at IIT Madras, and is part of the Airbus Accelerator. This company uses 3D printing to build launch vehicles and engines.
Dhruva Space, based in Hyderabad, is a National Award-winning start-up that offers full-stack space engineering solutions from ground stations to launch solutions and satellite platforms.
Skyroot Aerospace is developing Earth-to-space transportation systems for both materials and people.

These startups, and many others like them, are based on the combination of decades of space research expertise from ISRO and VSSC, and the new generation of IT entrepreneurs. The new entrepreneurs have an understanding of how to win over investors with deep pockets and the appetite for risk.

This industry faces two unique challenges: massive amounts of capital and long development cycles. Companies in this area are not just developing software. They are building physical products which must go through an extended design, development and testing process, are highly regulated and require precision engineering.

Ancillary manufacturers of aerospace components and assemblies face new challenges to supply these startups. Aerospace-grade materials and components require special design, materials sourcing, transportation, manufacture and storage.

PCBs used in aerospace equipment must be able to withstand extreme temperature, high humidity and excessive vibration.
Their lifecycle must be measurable in decades.
In some cases, replacing a PCB may be nearly impossible – for example, a PCB used in a GPS satellite.
Aerospace PCBs must be absolutely uncontaminated to perform reliably.
PCB size is severely restricted by the high cost of transporting equipment to space.
Aerospace PCBs are also highly complex, requiring double-sided and multi-layered designs.

Many of these challenges have no Earth-bound equivalent. Replacing a PCB in an aircraft engine is expensive, time-consuming and complicated, but it is possible; replacing one used by an orbiting satellite is near-impossible. Solving these challenges requires new and revolutionary thinking at every step of component/assembly manufacture.

Podrain works with several of these startups. We are AS9100-certified as a top-quality manufacturer for the aviation, space and defence industry. Podrain is one of the few EMS companies in India with this level of quality. This is an exciting new industry for us. There are many new challenges and problems to solve. The possibilities are only growing.

Will private spacefaring companies be able to sustain and be profitable in the long run? India’s low-cost, improvisational manufacturing philosophy and engineering expertise make Indian EMS companies perfectly positioned to manufacture aerospace components. Podrain sees huge domestic and international potential for Indian EMS companies as space becomes democratised. Podrain stands ready to seize the opportunity.

Electronics have become essential to daily life. Everything from refrigerators to military aircraft contains electronics. Today’s critical advanced assembly challenges mainly fall into three categories: performance, usability and productivity. To build and visualise product designs quickly and economically, engineers must address all these challenges.

On the other hand, manufacturing techniques are becoming more advanced and aesthetics are increasingly in demand. Project lifecycles and budgets are constrained. Sometimes, these constraints mean that DFM standards are overlooked in PCB design. For example, if the PCB has to fit in a box of fixed dimensions, the PCB design has to be tweaked accordingly. Or, components with different reflow profiles may be used on the same sid

Newer design houses or inexperienced engineers and designers may be prone to these mistakes. But not validating designs with tool and industry standards is bad practice. Here are just a few examples:

Pad mismatch

If the copper termination pad separates partially or completely from the board, it can be hard to identify the fault; the pad may look intact as the solder usually remains attached to the component. The cause is usually mechanical strain that begins during testing, manufacturing, vibration while being transported or even when connectors are attached. PCB performance is impaired and performance is inconsistent. Extensive or even destructive testing may be required to positively identify the cause. Podrain follows a painstaking process to minimise the risk of damage from pad mismatch at each step.

No silkscreen.

The silkscreen does not impact the electrical functionality of a PCB, but it is still extremely valuable as it provides essential information when assembling the PCB. It provides simple visual feedback that helps to catch deeper problems. It is not merely for aesthetic purposes. It is information that should not be separated from the board. Unique ID numbers, warning symbols, certifications etc. should be displayed on the board. At Podrain, we treat correct and comprehensive silkscreens as an integral part of the PCB.

THT vs. SMT components.

When SMTs were developed in the 1980s they were expected to completely replace THTs. But THTs and SMTs are not always interchangeable. THTs offer reliable and useful in test and prototyping applications where frequent manual adjustments and replacements are needed. But SMTs are almost always more efficient and cost-effective. Podrain’s extensive experience in a wide range of applications gives us the expertise to know which type of components to use for a given project.

Incorrect polarity marking.

To prevent polarised component packages from being inverted during assembly machine setup or manual soldering, accurate polarity marking is critical. It is only necessary for land patterns that have a specific rotation during assembly. Incorrect polarity markings can cause equipment damage, short-circuiting, serious injury, fires or even explosions. Podrain follows stringent Post Assembly Inspection Process protocols to visually validate that assembly insertion is done correctly

Incorrect component separation.

Most designers are used to PCB clearance rules for spacing between traces in a single layer. However, many design houses overlook PCB clearance between layers. Today’s circuit designs often involve a single PCB with power and controls on the same substrate. This may put high-voltage traces close to low-voltage signals, creating a risk of arcing. The resulting sparks can permanently damage the port of the low-voltage component. Podrain designers and engineers keep ourselves up to date on the latest IPC-2221B design standards to ensure optimum manufacturability with minimum risk.

Podrain’s customers have brought us some interesting design challenges.

A top manufacturer of electric vehicle charging stations found that the PCBA yield was below 90%, lower than expected. The company approached Podrain to investigate. The issue was all the more challenging because the assembly was ROHS. Planning and finding the right profile, especially on a PCB that uses BGA + LGA, is an art. By devoting our experienced people to solve this, we iterated through a range of 11 temperature profiles in a reflow oven within just 2 days to find the solution.

Another customer set us the challenge of setting the right profile for a board designed with a heavy BGA connector having multiple ceramic BGAs, including micro BGAs, on a 2mm thick PCB. The issue is these kind of connectors use very high temperature for soldering. 265 degree Celsius plus is needed for soldering but a normal BGA can tolerate only 245 to 255 degree Celsius. We designed and conducted multiple trials by changing the solder paste for each profile. After 15-20 trials supported by some fixtures, we were able to determine the best profile for the customer’s board.

Podrain has solved many such complex assembly design challenges for our customers.

Increasing Share of Electronics in AUTOMOBILES

October 22, 2021
No Comments

Many recent news articles have pointed out the effect of semi-conductor chip shortages on automobile output. There will be 7.7 million fewer vehicles produced and over $210 billion in revenue lost in the year 2021 according to some reports.* This has taken many consumers – who don’t realize the extent of shift in automotive technology – by surprise.

Cars now contain more electronics than ever and their share is only growing. According to this research report from McKinsey & Company, software and electronics have become the focus of most automotive companies. Power Electronics, growing at 15% , sensors at 8% and ECU’s /DCU’s growing at 5% plus will drive the global size of the automotive electronics industries to $469 billion by 2030.

At Podrain Electronics we are working with automotive OEM’s and other players as they ride the wave of change.

Automobile OEM’s are shifting gears into electronic mode:

Automobile components that were previously electrical or mechanical systems are now getting an electronic layer. For example, we have worked with a major Indian automotive manufacturer on the prototype “anti-pinch” window sensors for their new range of SUV’s. The electric motor, which operates the power window is fitted with a sensor that can sense any obstacle and stops the winding action. Parents of fidgety children who like to put their hands out of a window or pets who like to stick their noses out into the breeze can drive easier, knowing this technology will keep them safer.

This example is the tip of the iceberg. Sensors are being used in engine, power, steering, braking and acceleration systems converting automobiles from electro-mechanical machines to electronic & software devices. For examples, a tire manufacturing OEM client of ours is integrating electronics to create a Tire Pressure monitoring system that will enable them to optimize tire pressure based on weight of the load, road and environment conditions. The ability to remotely monitor the performance of their products opens up new opportunities to provide extended support , warranties and differential pricing for them.This is only one example of an OEM whose product and commercial model are changing to suit the times.

Fleet Management & Allied Services need electronics in automobiles:

We have supported clients for GPS and Vehicle Tracking Systems manufacture – another growing space of automobile electronics. There are several use cases for Fleet Management Solutions. They help track on-time arrival and departure of vehicles, fuel consumption, route monitoring and modification, safety tracking etc. Fleet management solutions and Asset Tracking are often done by other businesses and not by the Original Equipment Manufacturer. According to Mordor Intelligence this will be a USD 22 billion in 2026** and we certainly expect to help many of the companies in this area.

The future of mobiility – whether you choose a traditional fossil fuel vehicle, an electric one or a hybrid – certainly involves electronics!

If you are looking for electronics manufacturing services support for your company contact us and we will get back to you at the earliest.

Solder Paste Choice

September 17, 2021
No Comments

Solder paste printing attaches surface mount devices to printed circuit boards. Over 70% of Surface Mount Technology defects are driven by solder problems.* The choice of solder paste can make a huge difference. As devices and their components become smaller, the solder connections are also correspondingly finer. Its hard to fill apertures for these small devices with coarser type 3 solder paste. Type 2 solder paste is almost never used on Printed Circuit Boards. Rather, it features in power and industrial products where the chip package is bigger.

Until 2017, India had easy access only to type 3 solder paste which has 25-45 microns powder size. While it is possible to use type 3 solder paste for lead pitch between 0.3mm and 0.02mm , the reliability and durability of the boards reduces. Type 4 solder paste yields better results in our experience. We also use a Solder Paste Inspection system to ensure the right amount has been used.

Podrain has been sourcing and utilising type 4 solder paste, even though it entails a 20%-30% higher cost for the past 4 years. Now, we see an across the industry move to Type 4 solder paste and even the manufacture of Type 3 solder paste is coming down. We are currently evaluating switching to type 5 solder paste which has a powder size of 15-25 microns for components that need to go on the smallest PCB’s.

So when you are looking for a provider to make your PCBA’s, go beyond looking at the machines on the assembly line, and ask what solder paste is used.

Printed Circuit Boards (PCB) constitute an integral part of many (expensive) electronic devices. The costs of failure of undertaking a full production run without adequate testing of the PCB are

very high. The ideal answer is a strong prototyping process which can help in identifying any design or performance issues. However, finding the right Electronic Manufacturing Service (EMS) partner for this early stage where volumes are small and the turnaround needs to be quick can be challenging.

Podrain Electronics, unlike other EMS providers ca- ters to this niche market of prototyping on small volume. Having high-end machines to build and test PCBA’s, Podrain caters to the complete needs and requirements of the customer. The company specializes in the supply of products with a fast turnaround without compromising on the rigor of testing. The typical customers for Podrain’s prototyping services are Start-ups and hardware design companies. “Prototyping needs us to be very flexible,” explains Shyam Chandran, CEO of Podrain Electronics. “We work most Sundays. There was one occasion when a client came in at 8 PM in the evening, wanting some- thing to be ready for a VC presentation the next day. We worked overnight. While we charge a higher price for such a quick ask, the result for our client can be priceless”, adds Shyam. The company has expertise in delivering complex assembly – BGA, PoP, LGA and other new modules that are introduced in the market. Podrain has the capability to assemble thin as well as flexible PCBs.

“Podrain Electronics caters to the niche market of prototyping on small volume.”

Rajesh Rajagopal, Director of Operations says, “We are seeing a trend for slimmer devices overall. One of our builds was for a smartwatch prototype for a leading Indi- an brand determined to deliver a world class product. We had to assemble a PCB of 0.4 mm thickness with a 0.2 mm BGA package. We constantly invest in keeping up our learning so that we can deliver the type of cutting edge products our clients design. We love this challenge

Shyam and Rajesh have both been in the EMS space for over 20 years with different organizations. They met while working for an EMS company in 2013. They put together the idea of Podrain Electronics specifically to cater to a gap they saw – an engaged EMS willing to work in the prototyping space using the type of high-end machines that the final manufacturing process will involve. In the past 3 years they have found many takers for these services. Shyam takes care of the business side, while Rajesh manages the technical and operations aspects.

The duo has big plans. Podrain is ISO 9001:2015 certified. The company has continued to invest in new- er machines including an X-Ray inspection machine. In addition to PCB assembly, Podrain does complete box build assembly. A set of reliable partners supply the plas- tic enclosures, sheet metal and cable harnesses which are then assembled, tested and packed out of Podrain. They are also doing evaluation kits for silicon chips for leading semi-conductor manufacturers.

The prototypes the company has partnered on are maturing into higher volumes and clients are requesting pro- duction support. The current location in Bommanahalli is just off the ORR and close to the start-up hubs of Koramangala, HSR Layout, Indiranagar, Jayanagar etc. But it’s pretty full. “We need to grow to keep up with our clients. We hope to start a bigger production facility in the near future. Perhaps in Electronic City, Bengaluru”, says Shy- am. And what about the original prototyping idea? Shyam further adds, “We will continue with this and start more prototype friendly units”. Rajesh continues, “Perhaps even one in Austin, Texas. The future is bright for us”.
