Robust Control for Die Attach Machine Recipe Management System

One of the problems facing the Die Attach engineers at Front of Line is the lack of control of their Die Attach Recipes. Currently, all Recipes are stored on a computer that is accessed by all users and transferred to the Die Attach machine using a diskette via a simple file copy operation.

This kind of setup is vulnerable to the tampering of the Recipes, which may lead to problems in the production line, affecting the quality of the product. It is also difficult in the current setup to know which user copied the Recipe or changed its contents, making those activities untraceable. Finally, the manual management of Die Attach Recipes by file copy raises the risk of human error. To increase the quality of production as well as to protect Recipes from tampering, a computer-based program has been developed to fix the issues in the current setup.

The Die Attach Recipe Management System, or DRMS, is a computer program that can do the following: (1) protect the Die Attach Recipes to prevent unauthorized users from accessing and changing them; (2) monitor users who access the Recipes; and (3) simplify the recovery and storage process to eliminate human error problems.
