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……
Let me share what we've learned about adhesive selection through years of rigid-flex PCB manufacturing and failure analysis. Choosing between acrylic and epoxy adhesives isn't just about initial bond ……
Let me share what we've learned about flex PCB endurance testing through years of product validation. The 180-degree bend test is where we separate robust designs from potential field failures, and ge……
Let me share some hard-won wisdom about a problem that's ruined more than one of my flex PCB projects: solder pad cracking in flexible areas. I've spent countless hours debugging intermittent connecti……
Flex PCB Impedance Control: The Real Impact of 0.01mm Thickness Variations Let me share some hard-won insights about a problem that consistently troubles high-frequency flex PCB designs: how minor ……
Man, coverlay bubbles. I've spent more time fighting those little nightmares than I care to admit. You get everything looking perfect, run it through the press, and bam—a constellation of bubbles star……
Alright, let's talk about rigid-flex. We all love it for solving tough packaging problems. But I've seen too many projects get bit by the same two issues: a bad transition from rigid to flex, and pick……
When you're designing a flexible PCB that might face heat - whether from environmental conditions or internal components - the substrate material choice becomes critical. Having worked with both PI an……
When it comes to medical technology, the evolution of flexible printed circuits has quietly revolutionized how we approach patient care. As someone who's worked with medical device manufacturers for o……
Let's be honest - when a rigid-flex PCB fails in your foldable phone or medical device, your first thought probably isn't "how do I fix this?" It's more likely "is this even fixable?" Having worked on……
