What’s New with IPC’s Validation Services
During this year’s IPC Fall Committee Meetings, held in conjunction with SMTAI in Chicago, I met with my friend Randy Cherry, director of IPC Validation Services. Since the inception of Validation Services three years ago, I’ve conducted video interviews with Randy at IPC APEX EXPO, and I've been tracking the growth and progress of this program. I decided that this would be a great opportunity to do a mid-year check-up on IPC’s Validation Service programs.

Patty’s Perspective: Take Me to Your Leader
We must have touched a real hot button when we decided to do this issue on leadership. When we sent out our survey on the topic, we received a lot of responses, which we’ll review in a separate article, plus many of our regular columnists were inspired to write on the subject.
Let's Talk Testing: Don’t Reinvent the Wheel—Find an Expert!
Back in the day when I was an engineer fresh out of college, I quickly learned that experience is the solution to many problems. Now that being said, experience comes in many forms…it could be knowledge learned from a textbook, it could be an observatory comment jotted down in a notebook, it could be a conversation with a co-worker or colleague, or it could be an Internet search that finds a scholarly technical article, etc.
One World, One Industry: Voting—A Civic Duty and Industry Opportunity
On Tuesday, November 8, more than 240 million people in the United States will have the opportunity to go to the polls and vote, make their voices heard in government, and influence the direction of public policy for years to come. Much of the world is closely watching with interest in this major U.S. election.
Sensible Design: The Little Guide to Resins
I would like to start this series of columns by going back to basics, questioning the core rationale for potting and encapsulation with resins, their fundamental chemistries and how each resin type differs one from the other—indeed, how their individual properties can be exploited to maximise performance under a wide range of environmental conditions.
Disruptive Technologies– VR, AR and Star Trek
This article and subsequent follow-ups will cover various disruptive technologies. During the planning stage for this month’s issue of The PCB Magazine, I was asked to consider a number of potential topics; two of them are areas that I am very interested in—augmented reality (AR) and virtual reality (VR), and 3D printing and security.

John Cardone on Designing Flex for Spacecraft
If you watched footage of the Mars rover driving all over the red planet, you’re familiar with some of John Cardone’s handiwork. He’s been designing rigid, flex, and rigid-flex circuitry for spacecraft since he joined JPL in the early ‘80s, and he’s worked on some of the more ground-breaking flex circuits along the way. Now John runs his own design service bureau, JMC Design Services, and he continues to design circuitry for things that blast off. I caught up with John recently and asked him to give us the straight scoop on designing boards for spacecraft.
Mil/Aero Markets: F-35 Declared Combat-Ready
Electronic subsystems are an integral part of all modern military fighter jets, with a substantial portion of the electronics supporting intelligence, surveillance and reconnaissance (ISR) systems, electro-optical/infrared (EO/IR), avionics, munitions and radar related subassemblies. This equates to a very high content of PCBs and SMT assembly requirements.

The Blackfox Advanced Manufacturing Program for Military Veterans
You might be wondering why you should hire a military veteran, especially if your company has nothing to do with the military. But hiring veterans can bring a wealth of benefits, and this article highlights them. It also focuses on the Blackfox Veteran’s Training Program, the first program of its kind to provide veterans with little to no industry experience with the skills to grow their careers in the electronic assembly industry.
Let's Talk Testing: Does your Product have a Military Application?
Just like any other industry segment within the circuit board world, the military sector has its own share of documents…and likely many more than most! These documents have been developed over the years to guide, shape, and test anything and everything that might go into a jet fighter, a radar system, a warship, a weapons system, etc.

Designers Notebook: Specifying Lead-Free Compatible Surface Finish and Coating for Solderability and Surface Protection
A majority of the components furnished for electronic assembly are designed for solder attachment to metalized land patterns specifically designed for each device type. Providing a solder process-compatible surface finish on these land patterns is vital; however, selection of the surface finish on the circuit structure, whether plated or coated, can be greatly influenced by the components’ terminal metalization and the specific alloy composition used for the assembly process.
The 21st Century PCB Factory– Designed to Eliminate Offshore Cost Advantages
Over 15 years have passed since North America and Europe ceased being the center of worldwide PCB fabrication and were supplanted by a Chinese market with low-cost labor, lax environmental requirements, and strong government support. In just a few short years, the superior offshore cost advantages of this new dynamic put volume PCB production in the West out of business, aside from the military and specialty technology applications contained in the few shops that continue to exist today.
Zentech’s Matt Turpin on IMPACT Washington, D.C.’s Benefits
At the recent IMPACT Washington, D.C. 2016 event in Capitol Hill, Matt Turpin, CEO of EMS firm Zentech discusses with I-Connect007's Patty Goldman his expectations on the event, its importance, and how, so far, it has helped the electronics manufacturing industry in the United States.
Against the Density Wall: Landless Vias Might be the Answer
I saw my first landless via multilayer while visiting NEC in Japan in 1985. You may not know much about landless vias. This has been a well-kept secret for the last 30 years, possibly because it is not permitted on military boards, and therefore, discouraged in all IPC standards. So when a company showed us their landless via boards, we said, "You can't do that!"
EIPC Summer Conference 2016, Day 2: Strategies to Maintain Profitability in the European PCB Industry
Delegates awoke to a gloomy Scottish morning on the second day of the EIPC Summer Conference 2016.

Beyond FR-4: High-Performance Materials for Advanced Designs, Part 1
In the past 40-plus years of PCB manufacturing, the primary material of choice has overwhelmingly been e-glass supported FR-4 resin laminates. This is due to the excellent dimensional stability and reasonably acceptable thermal performance (based on glass transition temperature [Tg] and decomposition temperature [Td]). In general, these materials exhibit impressive performance and excellent cost for a wide range of applications.

IPC President John Mitchell on the Past, Present, and Future, Part 1
We conducted this interview with IPC President John Mitchell on the show floor at IPC APEX EXPO to discuss the event, the changes on the IPC board, and the key metrics that IPC uses to measure their own performance and effectiveness. John also invites the industry to a unique challenge.
Catching up with…PNC: Open House Planned for May
I’m a great believer in open houses. Any time customers and vendors get together to learn and talk about what they can do for each other it’s a good thing. That’s why, when I heard that PNC, in Nutley, New Jersey, planned to hold an open house on May 20, I wanted to learn more about it. So I called my friend Sam Sangani, the company’s owner, to learn more about it.
Karl's Tech Talk: Green Legislation and the Impact on Electronic Materials and Processes
In general, “green” and “environmentally friendly” refer to manufacturing that involves the replacement of toxic substances with less toxic materials, the elimination of materials or processing steps, less consumption of chemicals (i.e., more efficient or higher yield processing), reduction of water use, reduction of energy use, less space requirement (i.e., smaller equipment footprint), recycling, and on-site recovery of materials.
