A method for manufacturing a solar concentrator cell module assembly within an integrated circuit process, which solar concentrator cell module assembly includes at least one solar device and which solar device includes one printed circuit board and one Fresnel lens. A printed circuit board is assembled according to a pre-defined circuit board base design layout that allows pick and place of a single solar concentrator cell chip onto a circuit board base. Connections are provided for the solar concentrator cell chip in a serialized or a parallelized arrangement on the circuit board base, and a plurality of openings are formed in the circuit board base below a backside of the solar concentrator chip to enable attachment of cooling fingers. A solar device based on a solar device layout is assembled using the assembled circuit board base and one Fresnel lens, the solar device having a solar concentration ratio by modifying the solar device surface versus the solar cell surface and covering a full extension of the circuit board base, which circuit board base provides means for interconnecting a plurality of the solar devices to one another to form the solar concentrator cell module assembly.

The present invention provides an improved method of handling product recall activities through traceability. One embodiment of the present invention involves gathering data in a multi-layered database architecture containing supply, process, test, and customer layers. The data is supplied to a traceability module which contains a search engine to link and access the data. The search engine enables a search by part number, lot number, serial number, time stamp, and date/time frame. A traceability analysis is generated from the search, allowing failure analysis of the data. This analysis is performed through an event list over the entire supply, manufacturing, and customer data, facilitating backward and forward traceability of parts and components of the parts. This failure analysis further facilitates automatic response such as automatic warning and automatic recall to manufacturers and customers.
