Abstract
Abstract An integrated management system is provided for automatically executing a procedure of reviewing and editing an assembly reference and a bonding specification used for manufacturing IC packages. The system includes a drawing management system (DMS) that creates the assembly reference, and a bonding specification drawing system that creates, based on the assembly reference, the bonding specification. The integrated management system further includes a DMS database server that stores and manages the assembly reference and the bonding specification, a DMS file server that manages a blank diagram, a package outline, a bonding diagram, and a standard file, and a DMS web server that provides a web interface to a user for permitting a remote access. In particular, the drawing management system has a bonding rule check module that verifies whether the bonding specification meets a bonding rule suitable for an automated wire bonding process. The drawing management system produces the standard file to be transmitted to bonding equipments.
