Is anyone conformal coating flex circuits?

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

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

Protecting flex during conformal coating

Electronics Forum | Mon Oct 14 15:13:52 EDT 2013 | esoderberg

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?

Cleaning assembled circuit boards?

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

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
