Abstract

Current board tracking processes utilize a barcode printed on a label. The current barcode proc- ess, utilizing fixed laser scanners is operating at 3.690. Another problem associated with this proc- ess is the maintenance of the barcode label printer, and the waste it generates. Because the barcode applied to the printed circuit board is not the same barcode that is applied to the final product housing, a database must be maintained that correlates the two barcodes so production data will be available for field return units.

TOUCH MEMORY BOARD TRACKING SYSTEM

by Marc Marini

  Current board tracking processes utilize a barcode printed on a label. The current barcode proc- ess, utilizing fixed laser scanners is operating at
3.690. Another problem associated with this proc- ess is the maintenance of the barcode label printer, and the waste it generates. Because the barcode applied to the printed circuit board is not the same barcode that is applied to the final product housing, a database must be maintained that correlates the two barcodes so production data will be available for field return units.

  These problems can be resolved by placing the board tracking information into an electronic stor- age device that is permanently attached to the prod- uct. One possibility would be to incorporate traceability into a memory device already designed into the product. However, this device may be destroyed during a field failure. A better solution would be to utilize a touch memory tag.

  This discussion centers on a touch memory tag and its use on a polyimide circuit board. A polyim- ide circuit utilizes some type of rigidizer material, usually Aluminum. Figure 1 below shows how the touch memory would be attached to the rigidizer. The product case would act as the ground for the touch memory probe, while the probe contact itself would interface to the touch memory case.

  A probe would make contact with the touch memory as the board passed by during...
