Abstract
A fixture assembly of a unique construction is provided for use with a decapsulating machine so as to prevent damage to a FBGA package during decapsulation. The fixture assembly includes a retaining gasket for holding and aligning the FBGA package in the decapsulating machine, a spacer element for protecting the solder balls of the FBGA package, and a cover for receiving the pressure from a spring-loaded arm of the decapsulating machine. As a result, the FBGA package is prevented from being over etched by the sulfuric acid during decapsulation. In addition, damage to the solder balls are prevented due to excess pressure from the spring-loaded arm.
