Zero-Defect Method for Labeling Reels for Components that are Tested 100%

Disclosed is a method for a self-contained test for tape and reel labeling of electrical components. The method uses a Universal Barcode to eliminate mislabeling. Benefits include elimination of secondary and tertiary labeling operations and component-level traceability.

Background

Currently, manufacturers of electrical components generate customer-specific labels for every major customer. To avoid incidents of wrong-parts failures, some of these customers perform an incoming inspection by examining one part from every reel of components received. This incoming inspection is costly, and increases the chances for false-failures and handling-induced failures. The inspection requires that packages are opened; once opened, humidity can be introduced, causing parts to fail. In addition, packages may be altered in such a way as to make them unacceptable for return to suppliers post-inspection.

General Description

The disclosed method proposes the development of a Universal Barcode (UB). Similar to the UPC code applied to all consumer items, the UB would be consistent across all suppliers and would eliminate the need for custom labels to be applied for each customer. The UB would include all data currently required: supplier name, supplier part number, quantity, lot code/date code, serial number, and country of origin. Each customer would need an internal database to link the supplier part number to the customer part number.

During the component manufacturing process, the supplier would first generate a work order that includes the UB.  The final manufacturing process steps (test, tape and reel, and label) would be merged into a single process step with a single piece of equipment. The unified test, tape and reel, and label (TTRL)...
