Does anyone have a novel idea on how to protect the flex area during conformal spray coating? Currently using Humiseal T30 on the flex but it has to be removed very carefully to insure coating stays intact on the board.

I have a customer that is requesting their flex circuit be conformally coated. Is this something that is done? Which coating would stand up to the stresses of flexing? Wouldn't that put stress on the components? Thanks! Shannon

How many times does it have to flex. There are acrylic conformal coatings that can be bent once to 90 degrees or so

Commonly done with Parylene.

have done it in the past, used silicon as it will flex,, however its not the most robust material! tends to peel/flake off.

| | | We have experienced poor adhesion of acrylic conformal coating to plastic bodied IC�s. The observed symptoms of this are a blistering or lifting of the coating at the surface of the component, although peel testing has revealed that this is no

I agree with the two other replies. Left alone, it is a defect. If it's just excess adhesive or coating, you can use IPC-7711/7721 'Rework, Modification and Repair of Electronic Assemblies' for guidance on removing. Section 2.3.1 explains how to te

A friend in the contract coating business said: "... ask why the wire is [teflon] coated in the first place, as only the solder joints should be coated in this situation as the flexing/bending of the wires will cause the coating to crack and flake of

Looking for a clear conformal coating that can protect a PCB outdoors in Southern CA. Board is 24" x .25" x .03125. Require product to withstand some flexing during installation because of its very thin profile. Must hold up to environment for 10yrs+

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
