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 ……
Let me clear up a common point of confusion I see in rigid-flex design. When we talk about reinforcing the flexible areas in rigid-flex boards, we're typically referring to adding localized stiffeners……
When it comes to flexible PCB surface finishes, I've seen too many projects derailed by poor choices. The decision between ENIG (Electroless Nickel Immersion Gold) and OSP (Organic Solderability Prese……
Here's a problem that keeps PCB manufacturers up at night: you're drilling metallized holes in rigid-flex boards, and suddenly the flexible areas start deforming. The holes end up misaligned, the wall……
Let's talk about something that seems simple but can make or break your flex PCB design: trace width selection. I've seen too many projects stumble because engineers treated 0.1mm and 0.2mm traces as ……
Here's something I've learned the hard way after twenty years in PCB fabrication: the order you laminate your rigid and flex sections isn't just a theoretical preference—it directly determines whether……
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……
If you work with electronics long enough, you'll eventually face the dusty reality of maintenance. Flexible PCBs in devices like smartwatches, laptop hinges, and industrial equipment seem to attract d……
