Abstract:
A manufacturing method comprising:providing a plurality of mounting substrates; providing a plurality of integrated circuit devices in multiple lots for assembling in a manufacturing process; mounting each integrated circuit device of the plurality of integrated circuit devices to a mounting substrate of the plurality of mounting substrates; placing a substantially unique identification code on each mounting substrate of said plurality of mounting substrates in a readable position thereon; placing an identification code on each integrated circuit device of the plurality of integrated circuit devices; correlating the identification code of said each integrated circuit device mounted on the mounting substrate with the substantially unique identification code of the mounting substrate; reading the substantially unique identification code of the mounting substrate of each integrated circuit device of the plurality of integrated circuit devices in each lot of the multiple lots; performing a series of assembly steps in the manufacturing process on the plurality of integrated circuit devices in the multiple lots through: generating data related to the series of assembly steps of each integrated circuit device of the plurality of integrated circuit devices through the series of assembly steps; and associating the data generated for each integrated circuit device of the plurality of integrated circuit devices with the substantially unique identification code of an associated mounting substrate of the plurality of mounting substrates for tracking the multiple lots of the plurality of integrated circuit devices.
