OK, so it seems you have a packaged device and you want to obscure which exact part it is to make it more difficult to reverse engineer.We use programmable IC, MCu. Now I need to hide the IC. What's the best solution for it.
Is potting compound is fine?????
Two things:Note that most RTV silicon emits ascetic acid while curing, and the acid is corrosive. If you do decide to use RTV, you need to use a type that is specifically recommended for electronics.
