Cynical Forecasters Might Want to Lay Off
We headed to IPC Apex Expo in late January not certain of what to expect. The backdrop, of course, was one of job upheaval. Blue chip tech companies were announcing large-scale layoffs, and the “disengagement” counts were starting to accumulate in striking fashion. To wit:
- HP: 4,000 to 6,000
- Dell: 6,650
- Google: 12,000
- IBM: 3,900
- Meta: 11,000
- Microsoft: 10,000
- Twitter: Everyone except Elon Musk and a couple of engineers brought over from Tesla*
This wasn’t wholly unexpected. Inflation, while trending down, remains stubbornly higher than pre-Covid levels. Fourth quarter sales slowed at many firms. The cost of money has ticked up for months. Companies have been hiring like mad for several years and what goes up – or in this case, out – eventually comes down, or in, at least somewhat.
Nevertheless, some of this seemed proactive, a rebalancing coupled with expectations that growth would abate in the coming year.READ FULL ARTICLE

ECIA GIPC Publishes Report on Paperless Certificate of Compliance Initiative
ATLANTA – The Electronic Components Industry Association’s Global Industry Practices Committee (GIPC) in February published a report outlining the results of a two-year initiative to create a streamlined process to digitally exchange manufacturer Certificate of Compliance documents. Analog Devices Inc. (ADI) agreed to participate in the pilot project with Digi-Key. They began with the manufacturers’ certificate of compliance while considering other compliance documents. The report from this initiative is available to industry.
The process for the exchange of compliance documentation in the electronic component supply chain is cumbersome and inefficient as it is still largely done manually. Compliance documents are currently in paper form and must accompany the components when shipped from the manufacturer to the distributor and on through to the end-customer. This, says GIPC, drives unnecessary costs with manufacturers, distributors and customers in the form of time and effort spent locating and tracking paper documents and the actual costs of printing and handling them. Throughout the supply chain, those responsible for complying with these requirements are dissatisfied and frustrated with this inefficient process.READ FULL ARTICLE

Foxconn Secures Manufacturing Site in Vietnam
TAIPEI – Foxconn has signed a $62.5 million lease with Saigon-Bac Giang Industrial Park Corp in Vietnam to build a new manufacturing facility.
The move to secure a new manufacturing site comes after the Apple supplier’s iPhone plant in Zhengzhou, China, saw an exodus of tens of thousands of employees and violent worker protests amid stringent pandemic control measures imposed during a Covid-19 outbreak that began in late October.
The Vietnamese site, located in the Bac Giang province east of Hanoi, was rented through Foxconn’s subsidiary Fulian Precision Technology Component Co. The lease will run through February 2057, the company said.

Nanocoating Webinar, Flex Circuit Presentation Highlight Upcoming Meetings
PCEA in April will host a free webinar titled “Engineered Reliability: Safeguarding Electrical Components and Devices with Nanocoating Technology” by Richard Weiland, director of Nanocoating Applications for HZO Inc.
Thin-film nanocoatings can protect critical electronic circuitry that is used throughout a variety of applications and can be a powerful solution to implement to ensure reliability. Only requiring nanometers- to microns-thin coating, plasma-enhanced nanocoatings are dense, highly cross-linked, multilayer films that create a physical and chemical barrier around components to enable an envelope around the circuitry at a molecular level. The result is dependable functionality in harsh environments that may include moisture, sweat, etc. Plasma-enhanced nanocoatings leverage various liquids and gas chemistries to provide fast deposition cycles that are repeatable and scalable to projects of different sizes, use environments, and performance standards.Read More

TPCA Advises Caution for Global PCB Outlook in 2023
TAIPEI – After growing 3.2% to $88.2 billion, negative factors like geopolitics, high inflation and high inventories will likely dampen the global PCB industry for at least the first half of 2023, according to the Taiwan Printed Circuit Association.
Continued chip supply uncertainty meant IC substrates became the counter to negative factors and even the engine for growth in Taiwan, Japan and South Korea. Strong demand from high-performance computing and further upgrades to end-user product specifications all factored in the global PCB market outperforming end-user sales. PCB makers such as Ibiden, Shinko, SEMCO and LG-Innotek saw chip carrier sales account for over 90% of their PCB business, meaning carriers accounted for almost all growth by Japanese and South Korean peers. On the other hand, Chinese companies that once enjoyed rapid growth all experienced a noticeable slowdown in gross profit margins and net profits due to their focus on other products.READ FULL ARTICLE
Changing of the Guard
The industry’s next generation is on the rise.
I am continually amazed at how many people I see and run into at each industry meeting or event – especially at technical meetings when I’m watching people leave one room and enter another for the next session. It strikes me a bit like watching the changing of the guard at Buckingham Palace – people leave one room to enter the next to do the same thing, and repeat!
One thing that makes our industry so strong and enduring is having so many people work together to contribute to developing and refining technologies, writing standards for those technologies and processes, and sharing their knowledge with others to fully understand those technologies and standards. And then as they say, “repeat.”Read Full Article
PCB Outline Transfer
Tips for better communication and preparation.
The PCB designer is often the recipient of a file or series of files that provide the working parameters of the board. These documents will come from a physical designer who does the mechanical engineering for the project. In some cases, the PCB designer wears that hat themselves.
When the PCB outline is straightforward, do it yourself. One-off test jigs come to mind. We’re probably working with a rectangle that provides ample real estate for the intended circuit. There will be room to grow and iterate, but also space for plenty of text to ease setup and debugging. Put a hole in each corner so standoffs can be installed to raise the board above the test bench.
While we’re at it, larger boards may require a stiffener that prevents flexing, which can put a strain on the solder joints. Additionally, wireless sections of the PCB require a shield to keep outside signals from affecting the radio. You may be asked to come up with drawings for those shield walls and fitted lids. The bigger picture requires a different perspective from what we use at the board level.Read Full Article
Electric Aviation Takes Flight
Effective electrification could hold the keys to the future of air travel and air superiority.
Many feel our lives enriched by convenient and fast mobility. Our societies and economies have become dependent on the ability to get places quickly in planes, trains and automobiles, but easy mass access to air and road travel now appears at odds with the survival of the planet. We need a zero-emission solution if we are to continue enjoying its benefits, and electrification based on renewable energy appears to offer a way forward. Adoption of electric vehicles is accelerating while development of the internal combustion engine for private automobiles has all but stopped. But what are the prospects for electric aviation?
As in the automotive world, the electric aviation landscape is populated by established aircraft constructors looking to protect their position and high-tech startups seizing the opportunity to disrupt. In the second category, the aptly named Eviation accomplished a first demonstration flight of its Alice full-electric plane in September 2022. As a nine-seater commuter, Alice is a potentially serious commercial proposition – perhaps one of the first. The demo lasted eight minutes, flying at up to 3,500 feet, which compares well with the Wright Brothers’ 12-second flight at Kitty Hawk in 1903. We have come a long way since then.Read Full Article
Permittivity vs Permeability: What’s the Difference?
Some areas of physics have considerable impact on PCB designs.
by Douglas Brooks, Ph.D.
PCB designers have had exposure to electronics (some more than others). And most of what we do falls under the field of electronics. But designers often have little or no exposure to physics. And some areas of physics have considerable impact on our designs. Here we look at two physical properties of the dielectrics we work with, and why they are important to understand (Note 1).
Permittivity. Why are some capacitors able to store much more charge than others? What is the relative dielectric coefficient associated with dielectrics and why does it matter? The answer relates to a property called permittivity. Before we get too far into this topic, we need to clarify some terms.
Dielectric constant is an out-of-date term that means the same as permittivity, εm. The permittivity of a vacuum, ε0, is given as 8.85418782 x 1012 Farads/meter. The relative dielectric constant, εr, or relative permittivity, is the ratio of the material permittivity to the permittivity in a vacuum, orRead Full Article
How Interconnects Work: Characteristic Impedance and Reflections
Understanding reflections caused by transmission line characteristic impedance and termination impedance mismatch.
by Yuriy Shlepnev
Analysis of “digital interconnects” is the analog problem in frequency domain where interconnects are simulated as transmission lines defined by characteristic impedance and propagation constant. Digital signals in interconnects are sequences of amplitude-modulated pulses that transmit bits between components. The “digital interconnect” analysis problem is technically an analog problem of pulse propagation modeling in time-domain. The sequence of the transmitted bits (1s and 0s) is the only boundary between the digital and the analog interconnect analysis domains. That time-domain analysis problem, however, is practically always solved in the frequency domain. The pulse or sequence of pulses are transformed into a superposition of harmonics or sinusoidal signals in the time domain (more on that in Shlepnev1) because it is mathematically easier and more convenient to model all types of signal degradation for the harmonic signals using phasors and complex analysis. Components on PCBs in the digital domain are just connected – 1s and 0s are supposed to flow seamlessly among the components. In the analog or RF/microwave domain, components on PCBs or in a package are connected with the distributed open waveguiding structures composed of traces and reference conductors and simulated mostly as transmission lines. To ensure the digital signal gets through, we build interconnect models that include all signal degradation factors important for a specific data rate.Read Full Article
A Quick Fix for Fillet Starvation
Not enough solder? Blame the via design!
by AKBER ROY
Vias in pads can be “solder thirsty” and suck up solder from pads at terminals during reflow, creating what may appear to be solder insufficiency at the joints. This problem is typical of a via-in-pad design. It’s unpredictable as well; solder will randomly tend to fill those vias during the reflow process and some locations may appear worse than others, for example.
With a via-in-pad design, solder paste printed through an aperture of normal dimensions for the “toe” end of a pad at a rectangular end cap connection (FIGURE 1) may not provide enough solder during reflow to make a good solder fillet. The fillet may appear to be “starved,” because much of the solder that should be available to form a good solder joint will have wicked down the via and away from the end cap. The volume of solder lost will vary with the size and length of the via, the size of the component’s solderable surface(s) area, and other factors.Read Full Article

Good Signs: IPC Apex Booth Traffic Suggests Busy Year Ahead
Exhibitors hope new products will keep the order books filled in 2023.
The good times of 2022 carried over into January as the industry turned out for one of the larger IPC Apex Expo trade shows in some time. The San Diego Convention Center show floor was humming for the better part of the first two days of the three-day event, and most of the more than 300 exhibitors seemed pleased with the attendance.
Most companies, in particular the assembly equipment suppliers, reported strong bookings for the quarter. Several added that they’ve raised their full-year forecasts as result of the surge.
A few years ago, there was a big push toward the connected factory. The branding and implementation of the machine-to-machine standard known as Connected Factory Exchange, or IPC-CFX, is now so ubiquitous, it was barely mentioned throughout the week.Read Full Article
Aligning Six Sigma Tools with Process Reality
Identify the areas of variance in stencil design and adjust SPI programming accordingly.
Automated inline solder process inspection (SPI) has the potential to deliver some of the highest value among all inspection steps because defects caught at this point in the process require minimal rework. It is simply a matter of cleaning solder paste off the printed circuit board (PCB). Additionally, good printing performance typically represents 80% of a successful SMT assembly process. As the bulk of workmanship-related defects tend to track back to deficiencies in solder paste deposition, closely monitoring control limits in this area has a substantial impact on eliminating defect opportunities.
Industry 4.0 technology, which connects production equipment and enables automatic correction based on trends data from SPI or automated inspection (AOI) equipment, opens the door to even better process control. As inspection imaging technologies have improved from 2-D to 3-D, the focus on solder paste inspection has gone from paste height to measurements which include volume and area as part of good process control.
Automated inspection equipment is only as good as its programming, however. As a result, variations in stencil design created to address design for manufacturability (DfM) considerations can create issues in the way SPI equipment calculates process capability.Read Full Article
Mom and Pop’s Revenge
Don’t underestimate the speed and execution of a smaller shop.
Def.: Mom and Pop Shop. A common characterization of a family-owned company, usually small, closely held, and tightly run under original or second-generation ownership; often used as a term of derision or condescension by members of large companies; unsophisticated, provincial, or parochial; perceived as lacking in the most current skills, tools, or manufacturing methods. Often viewed as predisposed to surviving as a business and ensuring family succession first, with growth for growth’s sake a secondary priority. Not innovative. Inflexible in business practices. Rarely for sale. Content to operate in their space. Stuck in their ways.
Your operation? Or perhaps someone’s cursory impression of it? Certainly you have heard someone belittle a company by saying, “They’re nothing more than a mom-and-pop operation.” How did you as an owner feel when you got wind of that summary judgment? Was your comeback equally dismissive and snap-judgmental (“Typical remarks by someone who’s never met a payroll in their life”)?
Console yourself that you know what you know. You’re here, actively and successfully participating in your local economy and our industry. You know you’d go crazy in a big company. The politics, the backbiting, the petty rules, the busywork, the layers of approval needed to get anything done, and the pointless mandatory “enrichment” sessions. Not for you. You’re unemployable in that environment. Which in a strange way may also be consoling.Read Full Article

“Effects of Concentration of Adipic Acid on the Electrochemical Migration of Tin for Printed Circuit Board Assembly”
Authors: Yi Sing Goh, et al.
Abstract: Continuous advancement in innovative electronic applications leads to closer interconnection spacing and higher electric field density, thus increasing the risk of electrochemical migration (ECM)-related failures. The ECM of tin (Sn) attracts great interest due to the wide use of Sn on the surface of the printed circuit board assembly. In this work, the authors investigated the effects of adipic acid (1 ppm–saturated concentration) on the ECM of Sn using the water drop test (WDT) at 5V. In situ observation and ex situ characterization of ECM products were carried out using optical and electrochemical techniques. Results show that the ECM failure probability is higher at intermediate adipic acidRead Full Article
