e speak so often of the maturing (“graying”) of the engineers and operators who work in the printed circuit industry, we sometimes overlook whether the same term applies to the companies that employ those individuals.
And yet that matzah ball is hanging out there, particularly when it comes to printed circuit design software.
The textbook definition of a mature market is when it has reached a “state of equilibrium.” This is characterized by “an absence of significant growth or a lack of innovation.”




In a regulatory filing, Elite said it sought to establish a North American manufacturing base and expand to the US to meet long-term market demand.
Rancho Cucamonga, CA-based EMD makes specialty laminates and prepregs for PCBs used in the aerospace, defense and semiconductor industries. Known also as Arlon EMD, it has been owned by Critical Point Capital since its purchase from Rogers in 2015. (MB)
Circuits West designs and manufactures PCBs, specializing in the support and design of complex, dense and high-speed applications.
“I am excited to take over the company I’ve seen my father build over the past 25 years and lead it into the future,” said Anderson. “This investment will help Circuits West grow, add capabilities and modernize as a PCB manufacturer, while continuing to provide our clients with a world-class product and unparalleled customer service.”
DPO added, “We became intrigued by the bare board fab industry after learning that many of our private equity clients were investing in the space. When we dug into the industry and visited over a dozen board houses, it became clear there was a spectrum of quality, and that Circuits West was clearly near the top. Chuck did a great job of growing the company and continuing to invest in technology. With Charles’ energy and experience inside and outside the industry, we think we can do something really special. We will differentiate based on speed, quality and customer centricity that we think will be unrivaled in the relatively sleepy PCB space.” (CD)
In a press release, Arcline Investment Management said, “The addition of Ohmega perfectly aligns with our specialty electronic components platform growth strategy to assemble a portfolio of companies with world-class products and customer service. We are excited to work with this talented team to accelerate Ohmega’s growth, while maintaining the company’s unique culture and customer-first mindset.”
“We are very pleased with the acquisition of Ohmega by Arcline,” said Bruce Mahler, VP and general manager of Ohmega. “Our commitment to the long-term supply of OhmegaPly to our customers is enhanced with this acquisition. We’re also excited by the prospect of working with Arcline and Kevin Perhamus, the president of Arcline’s specialty electronic components group, and know Arcline’s commitment to investing in Ohmega and OhmegaPly will serve our customers well for many years to come.” (CD)
IPC said industry experts believe a five-year, $40 million investment in a public-private R&D program would yield more than $100 million in US defense savings per year and improve military readiness and overall innovation. Congress provided $5 million for such R&D in FY 2020.
SMTC’s board of directors has unanimously approved the acquisition and recommends stockholders adopt the agreement.
“Over the past three years, the team at SMTC has done an excellent job of transforming the company into a global leader among midsize providers of end-to-end electronics manufacturing services by offering superior supply chain management and proactive services and solutions to an expanding base of customers,” said Ed Smith, president and CEO, SMTC. “Partnering with H.I.G. will enable us to accelerate our growth through continued investment in our customers, capabilities, and footprint.
ACC Electronix installed two CyberOptics SQ3000 3-D SPI/AOIs.
Akyumen Industries will invest $100 million in a new facility to make 5G smartphones in Gary, IN.
Apple suspended new business to Wistron in Narasapur, India, in the wake of worker riots in late December. Up to NT$200 million (US$7.1 million) in damage was caused. In response, Wistron fired the head of the factory.
ASE, Chunghwa Telecom and Qualcomm unveiled a 5G smart factory in Taiwan.
Baidu, the Chinese search giant, is reportedly considering making its own electric vehicles and has held talks with automakers about the possibility.
Last July, OEP bought the EMS assets of Sparton Corp., which has since been renamed Spartronics. The combined companies will have annual revenues of around $420 million, a source with knowledge of the transaction told CIRCUITS ASSEMBLY.
AEM is offering S$1.15 in cash, or a mix of cash and new AEM shares, for each ordinary share in mainboard-listed CEI.
CEI shareholders can opt to accept the offer for either 85% cash and 15% new shares, or 70% cash and 30% new shares at an issue price of S$3.55 for each new share in AEM.
Founded in 1999, CEI has annual revenues of about $100 million primarily from customers in the industrial equipment market. It operates sites in Singapore, Indonesia and Vietnam. (CD)
With the relocation, the company continues to reside in the Greater Pittsburgh area and gains more square footage in anticipation of future growth. Intervala finalized the five-year lease for the 217,000 sq. ft. space, including several extension options.
Trends in the U.S. electronics equipment market (shipments only)

Stagnation has many causes, which can take a long time to do damage. Most common are simple things, such as when a company slows or stops development of new products or capabilities, or when it takes existing customers for granted while not working to develop new ones. Most common is when management stops investing in needed equipment or workers to make the bottom line look better, quarter after quarter. Each of these decisions are made, consciously or not, by management. And while the intentions may have been good, over time they become the root cause of stagnation and can bring a vibrant company to its knees.
What a difference a year makes. As I write this, three Covid-19 vaccines are approved and are in distribution to healthcare workers and nursing homes. By the time this is printed, it’s likely the next tier of eligible recipients will be able to get a shot at a pharmacy or their doctor. The speed of development, manufacturing, testing and deployment is unparalleled. The teams involved in this have set the stage for a return to normalcy. Yet it is likely Covid-19 will have a global impact on business travel and selling processes for most of 2021, because it will take time for herd immunity to develop. So, what should sales and marketing teams in the electronics manufacturing services (EMS) industry expect as we transition back to normal?
The need for speed. OEMs discovered some EMS companies could cut new product introduction (NPI) time significantly during 2020. The bar will likely stay raised, both because it provides competitive advantage and because unanticipated variations in demand require it. Companies able to exploit their success in this area will likely see additional new business.
One of those pieces of equipment was microfilm. You might recall microfilm stores many drawings in a small space. Bringing those tiny pictures back to human-readable sizes would lose some of the sharpness of the data. Standards were set up so we could still make out the images and data with no doubt about what we saw.
These concepts were associated with some particularly challenging, if not nasty, displays of societal failure in 2020. It has been easy for us to see how, in an agitated and perhaps desperate social climate, a time-consuming, methodical approach to collecting data and applying them to science can give way to convenient conspiracy theory. Speaking truth to power got some people fired overnight. The term systemic was used to point to long-term causes for some particularly blatant failures of a society to prepare people for success.
The flow of technology and know-how may soon be seen in reverse, as the aviation industry seeks to clean up its environmental credentials. In my last column, I mentioned Airbus’ recent flying achievements with fully electric planes. The company is also experimenting with hybrid platforms powered by a combination of lithium-ion batteries and a range-extending combustion engine, and recently unveiled several new hydrogen-powered concepts.

In pursuit of an answer to these and other questions, PCD&F in January reached out by email and phone to the top vendors of ECAD tools. We heard back from all but one. Their perspectives are aggregated here, with some edits for length and clarity.
This paper documents an investigation of the impact of bottom-terminated component (BTC) package construction on solder joint integrity using thermal cycle testing (-55° to +125°C) in accordance with IPC-9701.

In this report, AIM’s application lab approximated a production environment in a multi-hour printing test to quantify the effect of under-stencil wipe solvent on solder paste performance. This experiment compared isopropyl alcohol (IPA) and a novel stencil cleaner. IPA is not recommended as an in-process stencil cleaner, but is often used because it is inexpensive, effective and readily available. However, IPA is not a constituent of solder pastes and can therefore cause changes to paste that will negatively impact performance.
Providing solderability on the tip of the pins is good: A solder joint will form on the pad after reflow. No criteria exist for a wettable surface on the tips of the pins. Often the protective plating is removed or smeared when the leads are cut and formed; they may or may not be solderable or last long. The issue is similar with quad flat no-lead (QFNs) and why there aren’t side joints on these packages. The base metal is exposed or the plating smeared on the pins.

Abstract: Scalability and device integration have been prevailing issues limiting the ability to harness the potential of small-diameter conducting fibers. The authors report inflight fiber printing (iFP), a one-step process that integrates conducting fiber production and fiber-to-circuit connection. Inorganic (silver) or organic {PEDOT:PSS [poly(3,4-ethylenedioxythiophene) polystyrene sulfonate]} fibers with 1- to 3-µm diameters are fabricated, with the fiber arrays exhibiting more than 95% transmittance (350 to 750nm). The high surface area-to-volume ratio, permissiveness, and transparency of the fiber arrays were exploited to construct sensing and optoelectronic architectures. The authors show the PEDOT:PSS fibers as a cell-interfaced impedimetric sensor, a 3-D moisture flow sensor, and noncontact, wearable/portable respiratory sensors. The capability to design suspended fibers, networks of homo cross-junctions and hetero cross-junctions, and coupling iFP fibers with 3-D-printed parts paves the way to additive manufacturing of fiber-based 3-D devices with multi-latitude functions and superior spatiotemporal resolution, beyond conventional film-based device architectures.
