Classification: G01R,H01L

Abstract:
A system associated with a wire bonding process, for detecting bonding status of at least a bonding wire of a package including at least a semiconductor unit and at least a package-connection-means, said system comprising:at least a carrier for supporting said semiconductor unit and said package connection means; at least an electrical conduction means contacting at least a selected one of said package-connection-means; at least a preset connection means for electrically connecting the selected one of said connection means and said semiconductor unit; a voltage source for providing an electrical potential difference between said electrical conduction means and said bonding wire; a detector for measuring, when said bonding wire is electrically connected to at least one of said semiconductor unit and said package-connection-means, a current passing said voltage source, and for providing, according to the measured current, at least a status indicating signal reflecting the bonding status of said bonding wire.
