  • Patent number: 6409878
    Abstract: An automatic decapsulation system for a device is disclosed. The system comprises an etch plate, an etch head, an acid resistant, high heat endurance and flexible sheet coupled to the etch plate, and a rubber gasket disposed between the sheet and the etch head. The sheet provides a precise etch window and a self-aligning gasket for the device. The rubber gasket creates a tight seal between the device, the sheet, and the etch head. A system in accordance with the present invention utilizes an acid resistant, high heat endurance and flexible sheet in combination with a rubber gasket to seal the device for decapsulation and to provide a well-defined etch window. In addition, the sheet being utilized as the gasket is also utilized as the fixture, thereby eliminating the need to align the gasket to the metal fixture utilized in the conventional system.
