Hello SMTA, We have some flex board assemblies that will require conformal coating. Coating rigid boards is nothing new, but this will be our first with flex. Are there any challenges associated with coating flex PCBs? on this particular assembly

Hi All! There were a few rigid flex assemblies brought to me this morning with some scratches in the coverlay of the flex. They are pretty minor, but they do go down into some traces a bit. I don't think the traces are really signal traces, but are

I think that the top secret part is mounted on a flex rigid board. And it only looks like it is a display with a ribbon connected to the yellow board. I think the yellow board and white board were made with the flex connection and the display mounted

Hi Brad, I don't know if this helps, but we had a policy of not accepting x-outs on rigids, and of max 10% per panel on Flexy boards (as long as the local fiducial was blacked out for the bad board) I'm always suspicious of x-outs as it points to pr

With a large number of you out there building rigid-flex boards. I am wondering first what kind of profile do you use and what are you peak temps. I ask these questions because we are finding that our boards have a high moisture level and we are also

Flexible circuits assembly is different from rigid board assembly. For some manfacturers, fpc assembly are some things more painful because the assembly quality is unstable. Recommend to check and hope these 2 blogs are helpful. Flexible Circuit Asse

What you do is reasonable. Some of these and other tests are covered in: * IPC-6011 - Generic Performance Specification For Printed Boards * IPC-6012A w A#1 - Qualification & Performance For Rigid Printed Boards

Thank you. IPC-2222 applies to rigid organic boards. It does not apply to ceramic boards. Since there is no 2222 analog for ceramic boards, I used 2222.

First place to look is IPC-6012A w A#1 "Qualification & Performance For Rigid Printed Boards". I'll look at it later to see what's there.
