System for yield improvement of manufactured products

A system for improving manufacturing yields, comprising:

• at least one manufacturing facility into which unprocessed parts enter;
• identification plan for said unprocessed parts, by which each unprocessed part is given unique and traceable unprocessed part identification data by assigning numbers to batches of parts and further assigning data related to positions within said batch of parts;
• processing equipment included in said at least one manufacturing facility by which said unprocessed parts are turned into processed parts;
• identification plan for said processing equipment by which each piece of equipment is given unique and traceable processing equipment identification data;
• identification plan for said processed parts, by which each processed part is given unique and traceable processed part identification data and which is relatable to said unprocessed part identification data and said processing equipment identification data;
• at least one computer terminal connected to a database into which said unprocessed parts identification data, said processed parts identification data and said processing equipment identification data is stored, and related, and which said data is retrievable to allow processed parts with defects to be traced to the processing equipment by which it was processed for repair or modification of said processing equipment.
