Film frame strip test is a method of performing final electrical device testing while still in assembly matrix format. Individual units are uniquely identified with resulting test values in a software matrix map and then proceed to the next step in the manufacturing process while retaining traceability. Since the devices remain in matrix strip format, multiple devices can be tested simultaneously, thus reportedly improving throughput and reducing the overall cost-of-test. Carsem says it has demonstrated up to octal-site testing on packages down to 2x2mm. This size package allows 3200 units to be tested on a single 8-inch film frame.
