Decapsulation of samples using a variety of acids, bases and solvents is performed at Priority Labs. Priority Labs uses multiple techniques to decapsulate devices either manually or by using a Nisene Technology JetEtch system. Manual decapsulation consists of dispensing acid on the surface of a package to remove the mold compound covering the die.

After the die has been exposed adequately, the unit is rinsed with a solvent before drying. Jet etching is the automated version of chemical decapsulation, using equipment known as a jet etcher. The jet etcher squirts heated acid on the area of the package that needs to be removed. During this process, the area to be etched is left exposed to the chemical etchant while the rest of the package topside is protected by a rubber gasket.
