If you're working with high-frequency rigid-flex PCBs that need to bend during operation, you've likely encountered this frustrating scenario: your carefully calculated 50Ω impedance shifts dramatical……
Thermal cycling tests reveal critical information about rigid-flex PCB reliability that simply can't be obtained through standard room-temperature evaluations. Having conducted these tests across auto……
Creating serviceable rigid-flex PCB designs requires a different approach than traditional layout methods. Through our experience maintaining industrial automation systems and medical equipment, we've……
Creating microholes smaller than 20μm in flexible PCBs presents unique challenges that demand careful process optimization. Through our work with high-density interconnects and RF applications, we've ……
Dealing with stress concentration in rigid-flex PCB designs requires careful attention to mechanical design principles. Through our experience with foldable devices and industrial applications, we've ……
Industrial environments present significant challenges for flexible PCB reliability. Through our work with chemical processing equipment and automotive manufacturing systems, we've developed effective……
Working with high-frequency signals in rigid-flex designs presents unique challenges, particularly when it comes to vias. I remember struggling with signal integrity issues in our first 5G module prot……
When we first started working on foldable display drivers, we quickly discovered that traditional PCB spacing rules simply don't hold up in flexible applications. The conventional 3W rule - where you ……
Managing heat in rigid-flex PCB designs presents unique challenges, particularly in the flexible sections. Traditional cooling solutions often fail because they can't withstand repeated bending cycles……
Putting chips and sensors together on flexible PCBs creates some unique engineering challenges. I've worked on several wearable medical projects where we learned these lessons through trial and error.……
Signal crosstalk in the multi-layer flexible zones of rigid-flex boards is a problem we've all faced. I remember a specific project involving a high-density wearable device where signal integrity issu……
Let me share what we've learned about managing undercut in flexible PCB manufacturing. If you've ever seen traces that should be 0.1mm come out at 0.08mm, you've experienced the undercut problem first……
