Today we’ll dive deep into the world of conformal coating. More and more assemblies are being subjected to conformal coating to protect the assembly from harsh environments. What’s leading the drive to conformal coat electronics assemblies? What types of conformal coating options are available? What are the advantages and disadvantages of each type?  For circuit assemblies, the protective embrace of conformal coatings ensures reliability, longevity, and performance. As technologies advance, so does the demand for innovative solutions to safeguard our electronic products.  Whether you're a seasoned industry professional, a curious tech enthusiast, or just someone who's new to the world of conformal coatings, this episode is your go-to source for in-depth information on the growing trend of applying conformal coating to circuit assemblies. So, join us as we peel back the layers, and immerse ourselves in the world of electronics protection, and learn how conformal coatings play a pivotal role in keeping our d

We are all aware of the supply chain issues our industry has faced. Beginning with electronic components, it has spread to so many other types of parts are industry relies on. Fortunately, it looks like we are beginning to come out the other end of the supply chain shortage. But the supply chain problems have further spread to the labor market. If you are in a position to hire people for your company, you know firsthand how difficult that process can be today. Adding to the level of labor acquisition difficulties is the great “Silver Tsunami,” otherwise known as the great retirement. As mentioned on Reliability Matters episode 130, the fact is, Baby Boomers are entering retirement in greater numbers. According to government data, from now until 2030, 10,000 boomers will hit retirement age each day. Millions will begin to officially retire. Some of these retirees are designated subject matter experts within their companies. Not only are people retiring, they are taking with them a vault of valuable knowledge.

Printed circuit board and multichip module design software revenue increased 6.3% in the second quarter to total $369 million, according to the ESD Alliance's latest Electronic Design Market Data (EDMD) report. The four-quarter moving average for PCB and MCM, which compares the most recent four quarters to the prior four, rose 11.7%. As a whole, ESD industry revenue increased 5.3% to $3.96 billion in the second quarter from $3.76 billion in the second quarter of 2022. The four-quarter moving average rose 9.5%. Wally Rhines joins Mike Buetow to explain the latest data trends.  

Baby Boomers are entering retirement in greater numbers. From now until 2030, 10,000 Boomers each day will hit retirement age. Millions will begin to officially retire. This is creating a terrific opportunity for young college graduates to enter our industry. Several years ago, I was a speaker at the SMTA, Pan Pacific Strategic Electronics Symposium in Hawaii. I shared my breakfast table with a longtime colleague, Dr. Ron Lasky, a professor at Dartmouth College. Over the course of breakfast, he asked me how I got into this industry and, more specifically, how I started my company. Dr. Lasky is an engineering professor at Dartmouth’s Thayer School of Engineering. He also teaches entrepreneurship to his soon to be engineers. Dr. Lasky invited me to come speak to his students. I was more than happy to take him up on his offer, and I have spoken to his students on the subject of entrepreneurship every year for the past several years. I have been impressed by the emphasis on entrepreneurship within the Thayer Sch

The Reliability Matters podcast is almost exclusively about reliability. Specifically, reliability of circuit assemblies. We discuss production best practices, design for manufacturing and reliability. Failure analysis, and more. We’ve reviewed the latest trends in industry 4.0, the connectivity of machine to machine and machine to management. We discussed big data and how to make all of our newly acquired data relevant and actionable. For all this to occur, our computers must function properly. They must perform the assigned tasks and communicate large sums of data. What happens to our production line if the computers stop functioning? What would happen if our network ceases to operate? We’ve all witnessed the airline industry grind to a halt recently due to computer failures and connectivity issues. The fact is, very few industries can function properly or even at all if the computer systems fail. I’m not referring to quality issues within the computer or network’s internal circuit assemblies. I’m referring

HDP User Group is an industry consortium made up of more than 50 leading companies that collaborate on research in order to reduce cost and time to market. Madan Jagernauth, marketing director and a project facilitator, discusses recently completed programs on low silver solder paste reliability, copper surface roughness models, the Pb-Free bare board materials project updates, and HDP's upcoming meeting in October with PCB Chat's Mike Buetow.

In recent episodes, we’ve covered high-level issues, such as hiring best practices, novel, training, methods, design for manufacturing, highly accelerated, life, testing, and more. On this episode, we’re going to go back to the basics. What common problems are assemblers experiencing today? What are the basics of assembly best practices? Which problems seem to live in perpetuity? To answer these and other questions, I’ve invited two of my favorite experts on to the show. If you’ve been in the electronics assembly industry for some amount of time, there’s little doubt you’ve heard of Phil Zarrow and Jim Hall. Phil has been involved with PCB fabrication and assembly for more than 36 years. He is president and principal consultant of ITM Consulting. Jim Hall has been involved in the electronics assembly industry for the past 27 years. He’s a principal consultant and resident Lean Six Sigma Master Black Belt with ITM Consulting. He’s also an instructor in the Lean Six Sigma programs offered at Dartmouth College.

Moisture. The industrial world has been fighting moisture since the beginning of the industrial world. From a general point of view, moisture leads to issues such as Mold and mildew Rust Wood rot Damage to building materials Microbial growth And so much more. In the electronics world, moisture creates a host of reliability problems including: Popcorning Delamination of conformal coating Corrosion Electrochemical migration Adhesion degradation (such as on labels and glues) And more. We wanted to dive into moisture mitigation, so Mike Konrad invited two guests to discuss this very topic. Dan Jenkins is sales manager and partner of the Steel Camel, an industrial solutions company specializing in corrosion and water intrusion control for fuel systems and industrial equipment. Prior to Steel Camel, Dan worked as consultant and instructor in the crane accident prevention industry. He has consulted to large organizations such as Shell Oil, and the United States Department of Interior. Dan earned an MBA from the Un

As all of you are well aware, Reliability Matters is all about reliability, specifically reliability of circuit assemblies. One challenge that seems to be persistent within our space is design for manufacturability, or DfM. If you’re a contract manufacturer, no doubt you’ve had the experience of being asked to build a product that seems unbuildable. One example that rings true was the introduction of bottom terminated components or BTCs. BTC’s are marvelous components. Because all the lead terminations are below the part, they permit highly dense component placement and highly miniaturized assemblies. They also presented a number of unique challenges in reflow, in many cases voiding, cleaning, and inspection. Like many other industries, we are not immune to the introduction of new technologies that may lack implementation knowledge. We then spend the next several years at technical conferences and symposiums learning us how to implement these new technologies. There are many acronyms in our industry that beg

David Schild, executive director of the Printed Circuit Board Association of America (PCBAA), discusses the latest government policy and legislation for printed circuit board manufacturing in the US, the roadmap for government investment, the trade group's recent annual meeting in Washington, and "exposing the flaw" in the US Defense Department's procurement process. PCBAA was founded in 2021 to advance US domestic production of PCBs and base materials. The organization is made up of corporate members of all sizes, and includes fabricators, assemblers and suppliers. This episode of PCB Chat is sponsored by PCB West, The Largest Conference and Exhibition for Printed Circuit Board Design, Fabrication and Assembly in the Silicon Valley, coming September 19-22 to the Santa Clara (CA) Convention Center.

Thermal interface materials are used for heat transfer in a variety of electronics applications. On this episode of PCB Chat, Claire Wemp, Ph.D, a thermal applications engineer at DuPont, discusses TIM1 materials (and explains the difference between TIM1 and TIM2), when and where they are used, who specifies them, and how they work. Wemp is also a member of the Society Women in Electronics, and in the second half of the podcast we talk about her experience in SWE, which dates to college, DuPont's role in recruiting, and how to bend the curve in attracting more women to STEM fields.  

We all strive to build products that are reliable. If you’re listening to this podcast, chances are you are concerned about or at least interested in reliability. Where does reliability start? Who is responsible for reliability? What types of reliability testing can be performed? Mike Konrad's guest on this episode will help answer these and other reliability-based questions. Dr. Christopher Jackson is a leader, engineer and logistic specialist who has helped many organizations work toward realizing business goals through improving the reliability of their products and processes. He is cofounder of online training company IS4, founder of Acuitis Reliability, established the Center for the Safety and Reliability of Autonomous Systems (SARAS) at UCLA after retiring as a lieutenant colonel having served 17 years in the Australian Army, where he was senior reliability engineer. Dr Jackson completed his Ph.D. in reliability engineering at the University of Maryland in 2011. Dr. Jackson has authored multiple reliab

The PCB/MCM design software market grew in the first quarter 2023, the ninth straight quarter of growth, according to the latest data from the ESD Alliance. Mike Buetow speaks with Wally Rhines, ESD Alliance spokesperson, and Merlyn Bruncken, market intelligence director with Siemens Digital Industries, about the record quarter, booming employment in the sector, and why the recovery in Japan be lagging the rest of the world.

When it comes to circuit assemblies, defects result in one of two situations. The preferred result of a defect is to capture it on your factory floor and repair it before it ships to the customer. The second scenario is referred to as an escape. That’s when the board ships to the customer and fails in the field. This is a scenario, all assemblers dread and strive to prevent. One way to prevent escapes is through the use of automated inspection or AOI systems. Mike Konrad's guests are Arif Virani, chief operating officer and cofounder of Darwin AI, and Bart Piwowar, CTO of Darwin AI, a manufacturer of innovative inspection systems. Virani is a technology leader with over 20 years of experience in the industry. He spearheads the company’s mission to transform manufacturing with a new standard for quality inspection using AI. DarwinAI’s solutions have been implemented at top electronics manufacturers to increase quality and efficiency while reducing waste. DarwinAI was selected by CBInsights for its AI 100 ann
