EIPC Technical Snapshot: Cleanliness

John Ling’s invitation to the fifth in EIPC’s series of Technical Snapshots was as droll as we have come to expect: “In these confined days of lockdown, and exhortations to stay at home and only go out for exercise, this only exercises the natural inclination to hop on a ‘plane to some sunshine.’ Although not the same as Factor 20, one of our webinars gives a high degree of protection from harmful ignorance, and you do not have to go out in the cold.”

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

We’re seeing an increase in optimism as more people are vaccinated and states under lockdown begin flipping open their shutters. This positive outlook is spreading, albeit slowly.

Predicting a ‘Roaring Twenties’ Innovation Boom

The 2020s have not started as anyone would have wished. The COVID-19 pandemic has exposed weaknesses in supply chains and in global manufacturing, yet this could still be the most innovative decade ever.

Quality and Continuous Improvement

The concern for quality control and reduced product variation can be traced back centuries. Archaic quality control methods were used by the Xia Dynasty in 2100 BC in ancient China. During the late 1290s in medieval Europe, guilds—the pre-cursor to unions—were responsible for product and service quality. From 1700 to 1900, product quality was determined by the individual craftsman’s efforts. At the close of the 19th century, Eli Whitney introduced standardized, interchangeable parts to simplify assembly.

5 Keys to Smart Process Success

Smart factories require the core underlying processes to be connected and “talking” to generate the data necessary to make real-time process decisions, that is, the IIoT (Industrial Internet of Things). In a truly connected factory, an ongoing continuous dialog between machines, business processes, suppliers and customers is happening in the background. This dialog is not only interactive, but proactive, as a constant stream of real-time data is tweaking and adjusting processes to drive improvement. It also provides time-critical information on how processes are operating, supply chain pipeline, and delivery status updates—all based on data.

The Future of Imaging and Inkjet Printing

We recently spoke to Ed Carignan of Technica, who outlines the current landscape for both direct imaging and inkjet printing and describes how the technologies have evolved over the years. He also details what’s next on the horizon.

Book Excerpt: ‘Thermal Management: A Fabricator's Perspective,' Chapter 3

Conceptually, a metal-core board is exactly like it sounds—the metal is in the middle of the PCB sandwiched between layers on both sides. Just about any PCBA that will contain active heat-generating components can benefit when designed on a metal-core PCB. On a conventional PCB, the standard FR-4 layers are relatively poor thermal conductors, and heat is normally dissipated from active components using vias and thermal pads, as discussed earlier.

EIPC Technical Snapshot: Business Outlook

A headline in a Sunday newspaper had caught John Ling’s eye as he composed the invitation to this fourth EIPC seminar: “Now, more than ever, we need to talk.” Thus, it is that EIPC decided to run another technical webinar, which was just like one of their in-person conferences, except no one had to travel—or got to enjoy a beer or excellent food with convivial company.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

This week’s news gave off every indicator that we’ve started a new calendar year. The news channels were busy with changes in leadership—both corporate and governmental—and changes in ownership. Changes in representation, too. Honestly, it was hard to sort out the news to just five top items. Be that as it may, here are five things we think you ought to read, even if you read nothing else about the electronics manufacturing industry this week: tradeshow coverage, strategic acquisitions, market discussion, and governmental advocacy.

Your Greatest Competition is Yourself

It really doesn’t matter who you think your external competitors are, because the only competitor that really matters is you. Of course, you will look externally to stay on top of latest trends, but when it comes to competition, just competing with yourself is a win. When you look at yourself as your greatest competitor you will start with a huge advantage: you already have great intel on how “your competition” thinks. Ask yourself, “What can I do to displace my ‘competitor’ and create something much better?”

What’s Driving Price Increases for CCL and Prepreg?

Demand for copper foil is increasing from both PCB and battery production for e-mobility, leading to an upward price pressure for copper foils as post lockdown pent-up demand starts to exceed capacity. Lead times are stretching and prices increasing, particularly for heavy copper foils (2 oz./70 micron and above) as capacity is repurposed to maximize square-meter output for lightweight foils to increase capacity for lithium battery production.

CES 2021 Coverage: A Virtual Show Floor

I write this on the final day of CES 2021, and I expect CES will never be the same. It will not revert back to what it once was. I also cannot imagine it stays a totally virtual show; in doing so, I feel it would fail. Does that mean I think the 2021 show was a failure? No, not at all. In fact, it was a very good event, particularly in light of the medical and political pandemic that we have been enduring.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

Hard to believe that a year ago, I was getting ready to attend DesignCon and IPC APEX EXPO and wondering if this Novel Coronavirus was going to cut into attendance from the Pacific Rim. Now, we’re accustomed to virtual trade shows. They’re not ideal, but they’re the best we can do while meeting in person is not possible. We’ve learned to adapt.

My View from CES 2021: Day 1

What a difference a year makes. One year ago, those of us who cover and attend CES were going from one press conference to the next; this year, we are at home going from link to link. Confusing and challenging, yes, but there are some advantages: no masks, only five steps to get to a restroom, being able to have three of four events or more displaying on your screens at the same time and being able to download press kits as needed. So far, many new devices are being introduced, but of course, they are all online, so you wonder if some of them really exist or are truly operational as yet.

TTM’s Approach to Stackup Design: Train the Customer

In this interview with the I-Connect007 Editorial Team, TTM’s Julie Ellis and Richard Dang drill down into stackup design, detailing some of the common stackup challenges that their customers face when designing for both prototype and volume levels, and offering advice to designers or engineers who are struggling with stackup issues.

Pete’s reporting, as readers know very well, is masterful; Pete’s pen can capture all the feel and vibrancyy of a technical conference—and his readership numbers often top our charts. No wonder then, that Pete’s favorite moment includes something he wrote going “viral” with the help of the UK government.

Chapter 1 Excerpt: The Printed Circuit Assembler’s Guide to Process Validation

The original principle underlying the IPC’s ionic cleanliness requirement was that the mobility of surface ions, detectable from SIR measurements, would correlate to a maximum value of detectable ionic elements permissible on the circuit surface. The industry required a test that was both fast and accurate for process control. Thus, a simplified ion chromatograph that was able to detect ionic elements without differentiation was created.

IPC Addresses Critical Industry Skills Gaps With Electronics Workforce Training

Over the past three decades, IPC standards and certification programs have played a critical role in protecting public safety and promoting excellence by ensuring the quality, reliability, and consistency of electronic products. In 2019, IPC worked with its global network of certification centers to certify over 108,000 individuals across 200 countries and 21 languages to seven IPC standards. The ubiquitous adoption of these programs speaks to the strong partnership forged between IPC and the electronics industry.

Chapter 2 Excerpt from the Book ‘Thermal Management: A Fabricator's Perspective’

Insulated metal PCBs (IMPCB) or metal-clad PCBs (MCPCB) are a thermal management design that utilizes a layer of solid metal to dissipate the heat generated by the various components on the PCBs. When metal is attached to a PCB, the bonding material can either be thermally conductive but electrically isolative (IMPCBs or MCPCBs), or in the case of RF/microwave circuits, the bonding material may be both electrically and thermally conductive. The reason that RF designers usually have the bonding material thermally and electrically conductive is that they are using this not only as a heat sink but also as part of the ground layer. The design considerations are quite different for these different applications.

Prices of Copper-Clad Laminates Continue to Rise

Forces within and outside the PCB industry have led to concerns over rising prices for raw materials of copper-clad laminates (CCL). Recently, two major explosions at epoxy resin plants in China had a great impact on domestic resin suppliers. Prices have risen steadily in 2020, with leading CCL manufacturers announcing price increases of 20-30% recently. As the cost of raw materials such as electronic copper foil, resin and glass fiber have risen, the cost for manufacturing CCL has taken off as well.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

Some years, the middle of December is marked by a distinct lack of news in PCB design, fabrication and assembly. Much of the industry often takes off around this time to get a head start on the holidays, or to squeeze in a much-needed vacation. But 2020 is not one of those years. Most of us aren’t traveling anywhere farther than the refrigerator this year, and everyone seems to still be working, albeit from their home offices. And companies in the PCB community continue to make news.

Happy Holden: ECWC15 Virtual Event a Success

This is the first Electronic Circuits World Convention that I have not attended in person since 1978. To refresh your memory, these are held every three years on a rotating basis. The HKPCA hosted this year’s conference and they kept up the fine tradition of collecting outstanding keynotes, nearly 60 technical presentations and myriad poster papers. HKPCA was also kind enough to provide English slides and translations. It is still possible to sign up and view the presentations. I have listened to 20 of the presentations, and hope to attend even more in the coming days as they are all worth watching.

Happy’s DIY Solution to Chemical Control

I confess. I am a control nerd and highly analytical. My second degree is in EE control theory, and I see the world in terms of feedback loops and black boxes. Early in my career, I was volunteered for the technical programs for the California Circuits Association (CCA), which was created by my mentor Clyde Coombs. In discussions with fellow process engineers, it was clear that the chemical process controls that HP could afford and allow me to put in place were not able to be duplicated by much smaller PWB shops.

Nolan Johnson recently spoke with the Pacothane Technologies team about the current drivers of circuit board technology and how that has influenced and increased their product development of lamination and lamination assist products.

Chapter 1 Excerpt from the Book ‘Thermal Management: A Fabricator's Perspective’

Heat cannot be efficiently exchanged with stagnant air surrounding a hot device; however, it can be transferred away from the electronic component to the PCB using thermal vias. A thermal via is a good conductor of heat that runs between the top layer and bottom layer of the PCB, dissipating heat through simple conduction. In simple terms, thermal vias are plated holes located under, or electrically connected to, a surface-mounted heat source on a PCB that allows heat transfer through the hole.
