 In order to protect the fragile die, epoxy is mechanically strong and very chemical resistant. Strong chemicals, mechanical abrasion, or heat treatments can be used to remove epoxy. This is the most common packaging and possibly also the hardest. In order to protect the fragile die, epoxy is mechanically strong and very chemical resistant.
