Encapsulation of PCB with Epoxy
Encapsulation of PCB with Epoxy
(OP)
Hello everyone,
I have to fully encapsulate a printed circuit board (PCB). I chose to use epoxy resin. Though, I would need suggestions about the molding: how can I mold a 3D fully covering shell around the PCB in order to achieve hermeticity? I don't know how to place the PCB inside the mold in order to put it in the center of the capsule. Thinking about using a support or something like this. Open to advises!! thank you in advance

I built a steel box where I set the PCB with connecting windows. Next, I select my epoxy resin based on requirements to encapsulate the PCB. Previously, PCB circuit is protected with other adhesives to consolidate and seal the PCB.

For lower volume boards, take a piece of glastic as a base and then use 90° angle glastic to make the frame (screw the angle to the base so make the frame. Caulk all the joints with a 100% silicone. Once everything has cured, apply a silicone grease across the entire inner surface of the mold. Add the board, epoxy and cure. Once cure remove the board from the frame. Wipe the frame to clean and apply a new coat of silicone grease.
In both cases you may need to use greased plugs, etc to temporally cover any areas that are not going to get epoxy.
Finally, I always preferred to use a soft epoxy as the potting compound.
Good Luck
