Latest Patents

Fujiwara's latest patents include a method for producing parts and substrate assemblies. This innovative system involves a substrate, such as a ceramic substrate, and a plurality of parts, including LSIs mounted on the substrate. The process begins with checking the LSIs for excess or deficiency using a collating device. After inspection, the LSIs are formed with solder bumps. They are then automatically arranged on empty work pallets as parts kits by a kit setting apparatus. These work pallets are moved into a stocker, where a host computer commands the mounting of the LSIs on the ceramic substrate based on information about the stocked pallet and the progress of the ceramic substrate. An LSI mounting apparatus reads the serial number of the introduced ceramic substrate and requests the stocker to deliver the corresponding work pallet.
