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

This week’s Top 5 starts with steps you can take to cultivate a culture of thriving. We also have bullish news from the global semiconductor sector, advice on how to tease out hidden cost drivers during the PCB design cycle, how the Altium-Ansys collaboration will affect design, and Happy Holden’s version of Occam’s Razor—three simple tools to keep your wet processes in line.

Impact of the Altium-Ansys Partnership on PCB Design

There’s a saying in electronics hardware design: “There are two types of electronics designers: those who have signal integrity problems and those who will.” This adage emphasizes the inevitability of encountering and the need to address signal integrity (SI) and power integrity (PI) issues.

Hidden Cost Drivers in PCB Design

I recently taught a CID+ course, and if you’ve ever taken a CID or CID+ course, you know that we discuss cost adders quite a bit. When I asked the class of 15 design engineers their ideas on the biggest cost adders, the first and strongest response: the project manager. Are you surprised by their answer? After over 40 years in the industry, I wasn’t. If you step back and look at the process of product development, you’ll see that many decisions that affect costs down the line really do take root with the project manager.

Dan Beeker: Outstanding in his ‘Fields’

At PCB East, I met with Dan Beeker, technical director at NXP Semiconductor, and a speaker at the conference. Dan always gives a spirited interview, so I asked him to discuss his class and challenges in the industry today.

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

There’s a lot going on in our industry right now. As you’ll see in today’s must-reads, there’s even innovation taking place in drill bit development. We also have articles on cutting costs during the design process, as well as a handy guide to each country’s tech sweet spots, and what it takes to thrive in this segment.

In Honor of the U.S. Labor Day

Sept. 2, is Labor Day in the United States, always observed the first Monday in September. In its official declaration, we learn that “Labor Day is an annual celebration of the social and economic achievements of American workers. The holiday is rooted in the late 19th century when labor activists pushed for a federal holiday to recognize the many contributions workers have made to America’s strength, prosperity, and well-being.”

Asymmetric Hybrid Printed Circuit Board Design: Warpage Considerations

The printed circuit board (PCB) accounts for a significant portion of the PCBA’s (printed circuit board assembly) BOM (bill of material) cost. Designs with hybrid PCB stackup are adopted to reduce the cost of the PCB by using less expensive laminate materials in layers that do not have routings for high-speed signals (e.g., power and ground layers). The conventional hybrid PCB stackup design is symmetrical in the middle. This engineering technique has been employed in the data center industry for quite some time. To extend the idea and optimize the purpose of hybrid PCB stackup design, the feasibility of an asymmetric hybrid stackup is currently being studied.

Why You Need to Take This New ‘Semiconductor Essentials’ Course 

Recently, Andy Shaughnessy and Nolan Johnson met with Soo Lan Cheah, the developer of a new IPC course geared toward PCB manufacturing professionals who have little to no knowledge about semiconductor manufacturing. With her background in PCB and IC design, Soo Lan brings a circumspect vision of these disciplines and how they are inter-related. You don’t need to know a lot of math to take this course, and you’ll come out with a much better understanding of the whole silicon-to-systems approach.

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

It is the last weekend before the much-celebrated Labor Day holiday, also known as the official end of summer. Though I am not yet ready for pumpkin spice lattes and heinously early Christmas decorations, I do relish the end of the heat. But the heat in our industry is not set to die down anytime soon, nor should it. Just about one month shy of the end of Q3 2024, things are looking positive for many industry members, so let’s make sure to keep the metaphorical pedal to the metal for a strong quarter-end and a great upcoming trade show season.

Navigating Cost Drivers and Sustainability in PCB Production: A Comprehensive Guide

In May, I had the privilege of presenting "Cost Drivers in PCB Production" to attendees at the SMTA Wisconsin Expo. This presentation, one of our most popular, received tremendous feedback, inspiring us to share our insights more broadly through a comprehensive white paper on the subject. One of my favorite examples to share from this white paper which really illustrates the impact of both cost and sustainability is panel utilization.

A French Design Community

The French IPC Designers Council is a unique conglomerate of 250 members from all parts of the industry: EEs, designers, CAD engineers, PCB manufacturers, EMS suppliers, OEMs, and even some in component packaging, that encourages individuals to freely exchange their design issues without commercial considerations. Thomas Romont, a PCB manufacturer’s rep with more than 20 years of experience, especially in the design for manufacturing (DFM) process, leads this association with support from IPC.

Cost-optimize Your PCB Design and Specifications

Knowledge is the key to identifying the small details that makes the big cost difference for your printed circuit board. There are many types of printed circuit boards and multiple choices between the development of schematic and BOM to PCB technology selection, electronic PCB design, mechanical and physical properties, and PCB specification.

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

It’s a holiday weekend in the United States, but the news doesn’t stop just because a few of us have the day off! You’ll have to pardon me; my ears are still ringing from the fireworks. Without further ado, here are the five things you should not miss from this week.

Collaboration Station

As a PCB designer working for an EMS provider, Kelly Dack has seen his share of boards fail because they were designed in a vacuum; the designer simply threw the design “over the wall” and hoped for the best. In this interview, Kelly discusses the need for collaboration between all the stakeholders involved in designing and manufacturing the PCB. As Kelly points out, IPC’s CID curriculum provides a great framework for setting up a collaboration culture in your company, and standards help enable this kind of environment.

UHDI Fundamentals: UHDI Applications for Medical Devices

Ultra high-density interconnect (UHDI) technology typically refers to advanced printed circuit board (PCB) manufacturing techniques that allow for a higher density of electronic components and interconnections within a smaller area. While not directly related to medical applications on its own, UHDI technology can indirectly benefit various medical devices and equipment by enabling smaller, more compact designs with increased functionality and performance.

Don’t Overconstrain Your Board Materials

When we started planning May’s issue, which centers on the use of traditional laminates in certain high-frequency PCBs, we knew we had to interview Kris Moyer and Ed Kelley together. Kris teaches advanced PCB design classes for IPC, and Ed is the former CTO of Isola and founder of Four Peaks Innovation. What ensued was a wide-ranging discussion on the evolution of “standard” PCB laminates and the recent trend by some OEMs to use these materials in high-frequency and even RF boards.

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

Much of our recent coverage focuses on being ready for the future—technologically and otherwise. We have news about APCT relaunching as AdvancedPCB, and an interview with Freedom CAD’s Scott Miller about their new leadership—young managers who bring new vision to the company.  We also have coverage of “Bold Breakthroughs: Women Reshaping the Engineering Landscape,” a webinar that celebrates Women in Engineering Day.

Scott has been chief operating officer of the company for quite a while, but he recently assumed a new title as new, younger managers moved up into top leadership positions. I asked Scott to discuss his new role, as well as the company’s move to keep looking at the industry in novel, fresh ways.

Bridging the Gap: Re-engaging Design and Manufacturing with Downstream

At PCB East in Boxborough, Massachusetts, I caught up with Joe Clark, co-founder of DownStream Technologies. In this interview, Joe walks us through how we got into our current situation, with design, fab, and assembly functioning in separate silos, and how DownStream and the IPC-2581 data format can help bridge this gap. He also discusses what we lost by moving from the captive model, and what we stand to gain by knocking down the walls between design and manufacturing.

Career Opportunities Are Knocking

Are workforce topics on your mind? In this market, of course they are! Finding and keeping qualified employees is continually cited as one of today’s greatest business challenges. That's why I-Connect007 features Career Opportunities in every magazine issue. Whether you’re looking to hire or be hired, check out the Career Opportunities section in every issue of our magazines.

Mustaches and Automation in Flexible PCB Fabrication

In any manufactured product, whether a house or a flexible circuit, there is always a raw material component in the overall cost. In the flexible circuit, flexible heater, and rigid-flex industry, sheet materials can account for 20–60% of the overall price. Admittedly, this is a very broad range, but factors, such as how common the materials are in the region where they are made, can cause this to swing one way or the other. Your actions as an engineer or sourcing agent have an impact on overall cost, which I’ll illustrate through the example of building a house.

He’s back, and in splendid form. Pete’s Starkey’s coverage of the EIPC Summer Conference, which took place June 4-5 at the European Space Centre, The Netherlands, is top notch. Joan Tourné from NextGIn Technologies emphasized that our attention must be focused on the interconnection ability of our PCBs and highlights VeCS as an alternative to the traditional plated-through-hole approach. Finally, Martyn Cauwe of IMEC discusses environmental impact and specifically, the need for a better, parametric approach to quantifying it, something European businesses are being required to do on the regular.

The Collaboration Culture

As the founder of Trilogy Circuits, the provider of design and assembly services acquired by Zentech, Charlie Capers understands the value of collaboration. We spoke with Charlie about the need for designers to collaborate with all the downstream stakeholders, the hurdles to solid communication, and why real collaboration (or lack of it) can make or break your deadline.

Traditional Materials, High-Frequency Boards?

Not long ago, high-frequency and RF boards required specialized laminates, which tend to be costly and difficult to manufacture. But now, high-frequency designers use traditional PCB laminates for certain high-frequency boards. How is this possible? For some insight, we asked Ed Kelley, founder of Four Peaks Innovation and former CTO of Isola, to discuss how traditional materials have improved and what this means to PCB designers and design engineers today.

PCB East Keeps Getting Bigger

PCB East is definitely on the move. The U.S. Northeast’s annual PCB design and manufacturing show went on hiatus years ago as sister show PCB West continued to expand in Silicon Valley. But PCB East relaunched a few years ago, and it’s been growing each year. Show managers said that attendance at the 2023 show was double that of the 2022 event. 

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

It’s been a great week. I spent part of the week at PCB East, which was held at the Boxboro Regency in Boxboro, Massachusetts. I haven’t been to Boxboro in about 20 years. The last time I was at PCB East in Boxboro, design instructor Mary Sugden had a hot plate and a supply of bologna in her room, because she preferred fried bologna to anything she could get in a restaurant. Never a dull moment with PCB designers! 

Overconstrain? Underconstrain? Selecting Materials for High-speed Designs

When selecting materials for a high-speed design, you need to be very familiar with the materials’ electrical characteristics, as well as the requirements of the PCB you’re designing. There are myriad details that need to be considered during the material selection process, and missing one iota can lead to your job being put on hold. We asked Stephen Chavez, principal technical product marketing manager at Siemens, to share his thoughts on material selection for high-speed designs. Steph discusses material constraints, stackups, and the cut-off point when a “traditional” laminate will (and won’t) work for a high-speed board.

Ultra high density interconnect (UHDI) has several potential applications in wearable electronics, primarily in enhancing visual experiences, data analysis, and communication.

Underconstraining Your Materials? Leave It to the Experts

With traditional laminates now sporting improved resin systems, some OEMs are choosing various flavors of FR-4 instead of high-speed laminates for their high-speed designs—even RF applications. Avoiding overconstraining your materials in high-speed products can lead to considerable cost savings, not to mention a more streamlined trip through fabrication.

Catching Up With Tom Yang of CEE PCB

I was in the Bay Area recently and met with my new friend Tom Yang, CEO of CEE PCB, a $450 million Chinese PCB fabricator. For too long, we have enjoyed the luxury of complaining about Chinese companies without even knowing who they are and what they do. That’s just too easy. My mission was to talk to a real live shop owner in China. With this interview, you will have a better and more personal understanding of CEE and the rest of the Chinese PCB industry.
