I made a small PCB with some RGB Leds (everybody loves those). The pcb is 19x19mm or so with a 2 row, 12 pin (0.1inch) connector on one end, on the opposite the SMD leds (with SMD passives).
I’d like to coat/surround this thing in clear resin/epoxy/silicone something so that 1. the LEDs are still visible 2. the pcb will be inserted/removed and otherwise exposed to an indoor, somewhat clean environment. So it’d be nice to protect the electronics mainly from normal indoor use and human interaction.
Conformally coating the PCBA would have been smart, but I missed that boat, and I already have them.
Options I considered:
- Heat shrink tubing the thing. Either clear or black with a cutout for the leds.
- I can dip the PCBA into something (held by the connector on the opposite end) but what that is, I’m not sure.
- 3D printing with translucent filament an enclosure. The normal trick here of course is just getting the top/bottom half to snap somehow. Although, I did leave myself two cutouts in the PCB for standoffs.
Clear heat shrink will probably be acceptable, but yeah, curious as to what y’all think.
Thanks for the help,
