Are you gluing the parts to the board? We had a similar situation where the glue beneath the component would add a 'fulcrum' point to the center of the device and when the board flexed the part would fracture.

We are looking for a way to cure conductive adhesive. I heard about curing times from 2 hours and more. But I also received information that curing can be done in 10 minutes at 120 C. Of course it also depends from the type of glue. But the question

I've never done flex boards so I cant't say what tolerances you would need to maintain. Does you stencil manufacturer provide a QA data sheet with your stencils? If so I would specify to them the critical apt sizes in areas and push it back on them t

I have a used MyData My9 machine that I've picked up recently and it has a problem with initializing that I can't figure out. It just gives an error stating "no z indicator value at all". I've replaced the flex board with the force sensors but that d

MPM has a new board support system called GelFlex. It can be used on UltraPrint 2000 machines as well as AP series, UP1500 and AccuFlex models. For more info, go to http://www.speedlinetech.com/mpm/gel-flex.aspx also, contact Chris Wild at Speedline

Yes, it does look like a typical crack due to mechanical overloading (bending) of teh component. Usually because of the board flexing Vlad

We have never coated flexible circuits, although these guys apparently do as a part of their FC fabrication services: https://gcaflex.com/why-is-conformal-coating-important-for-flex-printed-circuit-boards/

Hi delnosa, Sorry about being 10 days late - don't get to the bottom of the page much. I'm working of layering flex circuits sandwiched between FR4 layers. The flex is primarily designed to take the place of interconnects like yours. I work in ap

Hi CW, Larger chip caps can be susceptable to cracking, but mainly this is due to handling - flexing of boards is the main culprit (the part being mechanically joined at both ends to the board). PCB's usually flex easiest along one axis, and larger
