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

Commonly done with Parylene.

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

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

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.

how does polyurethane used for wood floor coating differ from urethane conformal coatings sold for circuit boards? where can i get uv tracer to put in oil based urethane?

First, what's wrong with some dewetting of conformal coating on component bodies? Second, there are chemistries that might be able to remove silicone mold release, but cleaning the chemistry is not easy without affecting the whole board, as you impl

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

Hi folks, I have a conformal coating application where I need the coating to be UV stable for a number of years without any crazing or cracking of the coating. I have looked for such a coating and have come up empty handed. Much of the circuit boar
