I-Connect007 Editor's Choice: Five Must-Reads for the Week
When compiling my Top Five, I tend to let the reader views guide my choices. Oh, sure, sometimes a news item is significant well beyond the reads it receives; that’s why this is an editor’s picks, not a strict Top Five. Still, readership habits inform my choices. That makes it even more interesting when a week demonstrates a theme so convenient as to seem contrived. Take this week, for example. In this week’s top five, four of the top five are news reports on mil-aero topics. You, dear readers, gobbled up the military and aerospace news this week. The outlier is, as we all would expect, a conference report from our very own Pete Starkey.

This week, we have quite a potpourri for you. There's good news about the PCB market. And as this year continues to surprise us at every turn, companies are discovering the true nature of their leaders. Todd Kolmodin has a great column about bosses and leaders and why the two words are not synonymous. Not to be outdone, columnist Barry Olney found a way to explain the wavelength of electromagnetic energy by using a chocolate bar and a microwave oven. We also have great articles by Sagi Reuven and Pete Starkey.

Good troubleshooting techniques involve considering a system as individual parts rather than as a whole. The same techniques apply to your work with multi-board PCB designs. Each board consists of a single unit that has its own lifecycle. Some product designs may use a single PCB design for multiple functions or for multiple devices. Others may interconnect multiple PCB designs to produce a complete, fully functional system.

Advantages of Using ZIF Connectors as a Termination Method
There are many types of connectors and termination methods available when designing a flexible circuit. One of the most common is the zero insertion force (ZIF) connector. The reason why the ZIF connector is so popular is that they eliminate the requirement for an added connector. They create a direct connection from the circuit to the mating connector reducing overall weight and cost. Here are a few general facts about ZIF connectors.
Show & Tell Feature: New Developments and Opportunities
“Elevate the Excellence of Electronics” was the theme for this year’s IPC APEX EXPO. As expected, the show set the bar high with technical sessions, professional development sessions, committee meetings, numerous networking opportunities, and an exhibitor list that included all aspects of the electronics supply chain. Columnist Tara Dunn explains how she repeatedly found herself interested in multiple sessions being hosted at the same time, and having to pick and choose which session to attend.
I-Connect007 Researchers Survey Industry on COVID-19 Outbreak Effect
In the last 24 hours, we surveyed our readers regarding the coronavirus (COVID-19) outbreak and its effect on our industry. After reviewing the first 100 survey responses primarily from North America and Europe, one-third of the respondents reported that the outbreak was having at least a small effect on their orders. Two-thirds of our readers have yet to see any effect on their orders.
Flexible Circuit Design Guidelines
Flexible circuit designs share many of the same challenges of rigid PCB designs, but there are also many differences and additional challenges. The very nature of a flex circuit being able to bend and flex make it as much a mechanical device as an electrical one. This creates a special set of requirements unique to flexible circuitry. Understanding how these requirements interact will allow the PCB designer to create a flex circuit that balances the electrical and mechanical features into a reliable, cost-effective interconnect solution.
Catching up With Midstate Electronics
Dan Beaulieu recently sat down with Susan Matteo, Joan Allen, and Gerri Wooten from Midstate Electronics’ sales team to discuss their company, how long they have been in business, the key ingredients to their longevity and success, and how they see the market today in general.

Decreasing Bend Radius and Improving Reliability- Part III
Application: Design guidelines to improve the flexibility and reliability of flexible circuits. Most issues that arise with flex circuits can be eliminated in the early stages of the design phase, and special planning must occur when the circuit is required to bend. Many novices will design a circuit that calls for bending the flex in too tight of a bend radius, which can cause damage to the circuit and lower the reliability of the end product.
Decreasing Bend Radius and Improving Reliability- Part II
Many of the issues that arise when using a flex circuit come from a lack of knowledge about how to properly design one, especially when the circuit is required to bend. Many novices will design a circuit that calls for bending the flex in too tight of a bend radius, which can cause damage to the circuit and lower the reliability of the end product. This series of articles will focus on the seven key aspects to consider when designing for maximum durability and maximum “flexibility.”
Flex Standards Update With Nick Koop
This month, I interviewed Nick Koop—director of flex technology at TTM Technologies, a veteran “flex guy” and instructor, and a leader of several IPC flex standards committees. Nick provides an update for the committees he’s involved with and discusses some of the challenges that he sees as more designers enter the world of flex.
Kirigami Inspires New Method for Wearable Sensors
As wearable sensors become more prevalent, the need for a material resistant to damage from the stress and strains of the human body’s natural movement becomes ever more crucial. To that end, researchers at the University of Illinois at Urbana-Champaign have developed a method of adopting kirigami architectures to help materials become more strain tolerant and more adaptable to movement.

Decreasing Bend Radius and Improving Reliability—Part I
Many of the issues that arise when using a flex circuit come from a lack of knowledge about how to properly design one, especially when the circuit is required to bend.
Standards: Why We Have Them and Live by Them
Have you ever designed a board but received feedback that it couldn’t be manufactured unless changes were made? Or maybe you’ve designed a complex board and sent it to the factory only to find out that the manufacturer didn’t build the board to your expectations? PCBs are becoming more complex, factory options are growing, and expectations for product life cycles are becoming longer.
