AVE BIG BOX stores learned lessons that can be applied by electronics manufacturers?

One of the big takeaways from the Future Compute conference on the campus of MIT in May was a definitive “yes!”

There, we heard about how some of the large retail chains like Target use software, hardware and data in all kinds of customer experiences.

Almost every employee has handheld devices tracking the billions of sensors and cameras in use across some 1,900 stores and 50 regional distribution centers. At each store, it runs about 100 different software applications. They look at traffic trends: When is the peak? When is the lag? And how can they be modulated?

ROI
All Stretched Out
Shipping, Covid-19 and inflation challenges rival supply chain issues when securing capital equipment.
When I made my 2022 capital investment plan, I never thought it would be my 2023 capital investment plan. However, with a couple minor exceptions, equipment will be put in service during 2023, not this year as originally planned.

I thought I was the exception, but in conversations with colleagues, I realize I am the current norm. A trio of events had the combined impact of making what should be simple investments in machinery and equipment anything but.

The most talked about, problematic event has been the strained supply chain. I am not sure exactly how much of the problem getting machinery and equipment is directly attributable to the supply chain, but it has indeed had an impact. When obtaining lead-time quotations, availability of parts, chips, etc., are always the culprit cited for the long length of time to build the equipment, whether a complex custom-built item or simply a copier for the office.

BOARD BUYING
PCB Panelization Costs:
It’s All About the Real Estate
Just like housing, a little extra size can cost a lot more.
Printed circuit boards in panel or array format increase the efficiency of the assembly operation, especially in volume applications. Takt time is greatly reduced, and handling of product is easier. However, rising material prices are cutting into that advantage because more material is required to produce those arrays.

PCB costs are based on the amount of raw material required to make a particular board. The metal finish, like ENIG or silver, plays a part in pricing, but it is the amount of fiberglass and copper needed that really determines the final cost.

The quoted price for most boards in panel or array format is based on a fabricator’s desired panel price for a particular technology or quantity, divided by the number of arrays (or pieces) that fit on a standard 18 x 24″ manufacturing panel. The more arrays or pieces that fit on the panel, the lower the cost.

FOCUS ON BUSINESS
EMS M&A: Will Your Exit Strategy Be Customer Beneficial?
Firstronic and Lacroix took a long-term approach to joining forces, eliminating the usual learning curve.
As a 40-year veteran of the electronics manufacturing services industry, I’ve seen my share of EMS mergers and acquisitions from both sides of the equation. The basic EMS industry business model adds complexity to that equation not found in most industries because EMS companies are an extension of their customers’ manufacturing operations or, in some cases, their entire manufacturing operation. If a larger conglomerate acquires the company that manufactures your dish soap, you won’t notice unless the product’s effectiveness or branding changes dramatically. If your EMS provider is acquired, it’s obvious on day one.

In many transactions, the only consideration of impact to an EMS company’s customer base is visits to key customers during the due diligence phase to enable the acquiring entity to assess whether the business levels they anticipate are likely to continue in the new entity. The alignment of EMS brand/differentiating processes and facility redundancy are often minor considerations.

The PCB East keynoter gives a roundup of innovative technologies to come out of the pandemic.
We have gone where no mask has gone before! The Printed Circuit Engineering Association (PCEA) held its first regional conference and exhibition in Marlborough, MA, in April.

A resurrected PCB East drew attendees from as far as the West Coast and Florida. There is nothing like in-person contact. The social aspect of networking has been missing for far too long. The enthusiasm of the attendees bodes well for future face-to-face regional gatherings.

Reasons to Go Beyond the PCB Constraints
Keeping some margin on the table increases the chances of immediate success and leaves a little bit for later.
There are many more ways to constrain a PCB layout than when I started my journey as a semi-intelligent designer. Guardrails were put in place to smooth transition into fabrication once the layout is completed. The other thrust of newer rules concerns the shrinking timing budget of our digital interfaces, particularly the memory banks.

We have so many aspects we can control that it can be tempting to disable or ignore some of them. That is a completely rational choice to make. New features take time to learn and implement. It may not be so easy to get everyone on board for a new feature or a whole new iteration of the software.

Onshoring and Second Sourcing
The current difficulties call for a more strategic approach to arranging our global supply chains.
The supply chain chaos in the aftermath of the pandemic has highlighted the risks associated with globalization. As a phenomenon, globalization has served many of us well. Its ideological opponents, however, see today’s situation as justification for its demise. There is no denying current events have highlighted shortcomings. We would be foolish not to learn and adapt.

I’ve addressed the subject of onshoring as a potential antidote to globalization many times in the past. Arguably, now, the idea makes more sense than ever. On the face of it, shorter supply chains promise some protection against the unpredictability of today’s world. Hot on the heels of the pandemic, we now have the Ukraine crisis, and there is the fallout from Brexit, which has made for difficult and time-consuming trade between the region’s most influential economies. One major obstacle to the return of onshoring is essential indigenous-supporting industries have been largely swept away as activities have migrated offshore, taking expertise and investment with them. The conditions that caused and drove the offshoring remain in place, perhaps masked by current logistical difficulties. Accessing the data needed to move manufacturing activities from an established location is another barrier to reshoring.

The Flexperts
Where is My Flex?
When designing a rigid-flex, start with flex in the middle of a stack-up and move outward.

You’re designing a new rigid-flex. Devices are getting fanned out, via structures defined, and layer count is becoming clearer. You have determined how many flex layers you need from rigid section to rigid section. There are competing considerations on how those flex layers are configured: foil and dielectric thickness, bonded or unbonded, and where they will be in the stack-up of layers. All this impacts flexibility and how the part will bend in the installed application.

For today, let’s concentrate on where the flex layers land in the stack-up and the effect that can have on manufacturing and end-application use. Several strategies have rational logic and can be successful in select situations.

siMULATION
Reflections from Discontinuities
A single one can destroy a signal, but predictions with validated models can be made. by Yuriy Shlepnev, ph.d.

An ideal digital interconnect is a lossless transmission line with characteristic impedance and phase delay flat over the signal bandwidth and termination resistors equal to the characteristic impedance. In such interconnect, bits generated by a transmitter would flow seamlessly into the receiver with no limits on the bit rate. Such a utopian transmission line exists only in our imaginations and textbooks. The physics of our world prohibit it. One way to describe “what happens to the signal on the way to a receiver?” is to use the balance of power that can be written for the passive interconnect as follows:

P_out = P_in – P_absorbed – P_reflected – P_leaked + P_coupled

This is frequency domain over the bandwidth of the signal.1 P_out is the power delivered to the receiver, and P_in is the power delivered by transmitter to the interconnect. All other terms in the balance of power equation describe the signal distortion. The formula above expresses all we need to know about the interconnects. (It should be “cast in granite.”). As they say, “a formula is worth a thousand words,” almost literally in this case. To understand it, imagine the interconnect system as a multiport with the transmitter at port 1, receiver at port 2 and multiple other ports for links coupled to the link connecting port 1 and 2 and terminations to real impedance (not necessarily identical at all ports) – something like this below, together with the definition of waves and scattering parameters (or S-parameters):

How to Calculate Trace Length from Time Delay Value for High-Speed Signals
Here’s an effective process for implementing PCB trace routing.
by Lance Wang
To keep a good high-speed signal quality from driver to receiver on a PCB is not an easy task for designers. One of the most challenging issues is managing the propagation delay and relative time delay mismatches. To manage the time delays, we need to know how to calculate trace length from time delay value to implement the PCB trace routing accordingly. Here’s the process:

According to physics, electromagnetic signals travel in a vacuum or through the air at the same speed as light, which is:

Vc = 3 x 108M/sec. = 186,000 miles/sec. = 11.8 inch/nanosec.

A signal travels on a PCB transmission line at a slower speed, affected by the dielectric constant (Er) of the PCB material. The transmission line structure also affects the signal speed.

There are two general PCB trace structures*: stripline and microstrip.

Will US Government Incentives Spur Domestic Investment?
Fresh off its inaugural meeting, the PCBAA gets legislative good news. What’s next for the organization that wants to rebuild US production?
by Mike Buetow
In early May the Printed Circuit Board Association of America, or PCBAA, held its first annual meeting, at which they shared progress on their overarching goal, which is to advance US domestic production of PCBs and base materials.

Coinciding with that meeting came an announcement from a pair of US legislators that they had introduced a bill to incentivize purchases of domestically produced PCBs, as well as industry investments in factories, equipment, workforce training, and research and development.

The bill, known as the Supporting American Printed Circuit Boards Act of 2022, is said to be modeled on the CHIPS Act of 2021, a much-touted piece of legislation that earmarks more than $50 billion toward new onshore semiconductor fabrication plants.

The
Production Sourcing Approach
Engineers looking to scale up production are victims of their success if they don’t have a long-term supply chain plan.
by Brian Laney
The situation: Your engineering team is looking to move from idea to production. You reach out to a contract manufacturer. Question: When does it begin to feel like a partnership?

As a business owner or engineer, working with a contract manufacturer can be daunting, particularly if it doesn’t have experience sourcing challenging parts in a challenging market. How can we as a community of manufacturers help solve this problem? We must put in the time to clearly identify the challenges, set aside time, and build resources to assist customers in real time – and offer a stratified path to a solution based on the type of client. Sounds easy, right? But don’t flinch when it comes to defusing bombs.

Recently, customers have tapped us to bring production to the US from Asia. These customers have been using turnkey, rapid-turn, low-volume solutions and are now looking at scaling production to about 1,000 from less than 100.

IC CLEANING
Defluxing of Copper Pillar Bumped Flip-Chips
A case study showed a well-balanced aqueous cleaning agent removed Pb-free, water-soluble tack flux residues better than straight DI water. by Ravi ParthasarathY and Umut Tosun
Solder bump technology is problematic below 150µm pitch, since it is challenging to manufacture and assemble. As the bump pitch size shrinks, solder bumps have many limitations in the fine-pitch process. Bump printing, plating or bump drops, along with bump pad sizes, are the major constraints; as a result, risk of shorts increases. Today, dies in production have as many as 25,000 bumps per die. It has been predicted this number will increase to 50,000 to 60,000 per die in the next year or two.1

Another form of bump gaining more popularity is the copper pillar. These bumps, instead of being spherical in shape, are in the form of a pillar, with various shapes and sizes. The most popular shape is in the form of a cylinder. The pillar shape allows the high ratio of bump height to bump diameter, therefore permitting very tight pitch, even when bump heights are large. Sometimes a solder cap is formed on top of the pillar to help with connectivity with the mating chip.1 Due to the cylindrical shape and non-collapsing nature of Cu pillar bumps, they can be easily mounted on the fine trace of the laminate. Copper pillars are terminals used to flip-chip IC chips to a substrate in a semiconductor package by thermal compression flip-chip (TCFC) technology. Copper pillars are formed on aluminum electrode pads of an IC chip.

This ink is alive and made entirely of microbes. Northeastern University researchers have created a bacterial ink that reproduces itself and can be 3-D-printed into living architecture. The microbial ink flows like toothpaste under pressure and can be 3-D-printed into various tiny shapes, a circle, a square and a cone, all of which hold their form and glisten like Jell-O. This new substance is not the first-ever living ink. Scientists have previously created printable gels that were cocktails of bacteria and polymers that helped provide structure when printed. One such ink contained hyaluronic acid, a seaweed extract and fumed silica. (IEEC file #12578, The NY Times, 11/24/21)

“A Review on Printed Electronics with Digital 3D Printing: Fabrication Techniques, Materials, Challenges and Future Opportunities”

Authors: C. Hanumanth Rao, et al.

Abstract: The introduction of 3-D printing technology has revolutionized the manufacturing and electronics product design in the past few years, where it is used to produce printed circuit boards. Printed electronics is one of the fastest growing additive manufacturing technologies and is becoming invaluable to various industries. The evolution of several contact and noncontact types of fabrication techniques has been reported in the recent past. Leveraging these technologies, various types of printed electronic components have been realized. One method is inkjet printing technology, which has been widely accepted for printed electronics manufacturing. As 3-D printing uses only those materials essential to create the product, it eliminates waste production, with a smaller equipment cost and minimizes the number of process steps, resulting in lower manufacturing costs with reduced turnaround time. Various kinds of conductive and nonconductive materials have emerged in the recent past in conjunction with many manufacturing techniques for printed electronics. Herein, the authors review the most commonly used substrates, electronic printing materials, and the widespread printing techniques employed at the industrial level, giving an overall vision for a better understanding and evaluation of their different features. The technical challenges of several contact and noncontact techniques with corresponding solutions are also presented. Finally, status on advances in the production of various kinds of materials employed in 3-D printed electronics and the methods for producing them, shortcomings, technical challenges, applications, benefits, and the future opportunities pertaining to printed electronics are discussed in detail.
