Decapping Ic Without Acid : 5. Etching - Integrated Circuits Manufacturing (IC)
Decapping Ic Without Acid : 5. Etching - Integrated Circuits Manufacturing (IC) . The ic is carefully lowered into the hot acid and a vigorous reaction ensues with the epoxy almost instantly decapping by hand is not only extremely dangerous, but it is done successfully by very few people. The process starts by milling a precise pocket into the ic using my cnc machine. Keep in mind, that using nitric acid is generally pretty nasty. The usual method for removing the epoxy package from the silicon is to use hot, concentrated nitric acid. Without water to create an ionized electrolyte, corrosion of metals will not take place.
