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.

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.

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.”

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.

Weaving Advocacy into E-Textiles
Electronic textiles (e-textiles) – fabrics that have electronics embedded in them to achieve certain functions – are of growing interest in the electronics manufacturing industry, and thus they are of growing interest to the IPC Government Relations team as well.
Selecting the Proper Flex Coverlayer Material
Coverlayers are polymer materials used to cover and protect the copper traces of the flex circuit product. There are a number of different options available for protecting the circuits, and they serve different design requirements in terms of cost, performance, and flexural endurance optimization. When specifying the choice, it is critical to call out not just the type of coverlayer material but also the thickness requirement. This can be very important in certain types of constructions, especially when a flex circuit will experience dynamic flexing during use.
Development of Flexible Hybrid Electronics

Learning to Be More Flexible: Case Studies on Improving FPC Design
As miniaturization requirements force manufacturers to pack more functionality into ever-smaller packages, it becomes more difficult to conform to IPC construction recommendations. Achieving robust FPCs requires frequent, iterative interaction internally among the mechanical, electrical, and PCB design teams, as well as with the fabricators and assemblers. The sooner in the design cycle you can engage the supplier and assembler, the better.
Brittle Pals Bond for Flexible Electronics
Mixing two brittle materials to make something flexible defies common sense, but Rice University scientists have done just that to make a novel dielectric.
