Not a real bug but still bugs me: The silicone case dissolves the beautiful epoxy layer and gives it pimples

ig me destroying the case while putting the CU in was a happy accident afterall lol but thats wierd, never heard of silicone just through contact dissolving epoxy...

Can you share the cleat production documents between the silicone casing and the upper and lower pcb?

ekoyle commented 8 months ago

This could also be caused by improperly cured epoxy (wrong amount of catalyst, not mixed well enough, etc), so it may be an issue with the process rather than a reaction with the silicone cover.

Just today I removed my Ultra from the silicone case for a while and noticed some unevenness on the epoxy. Shrugged it off as "always been there" but this makes more sense.

That said... What the actual heck!
