A system for producing parts/substrate assemblies each of which includes a substrate such as a ceramic substrate and a plurality of parts such as LSIs mounted on the substrate. After the LSIs for one lot of the production have been checked for excess or deficiency, etc. by a collating device, they are formed with solder bumps and then inspected. The LSIs are automatically arranged on empty work pallets as parts kits by a kit setting apparatus, and the work pallets on each of which the corresponding LSIs have been arranged as the parts kit are moved into a stocker. A host computer gives a command for mounting the LSIs on the ceramic substrate on which they can be mounted, on the basis of information indicating the stocked pallet and information indicating the progress of the ceramic substrate. An LSI mounting apparatus reads the serial No. of the introduced ceramic substrate, and requests the stocker to deliver the work pallet on which the associated LSIs have been arranged as the parts kit.

System for producing parts/substrate assemblies

A method of supplying parts in a system for assembling a printed circuit board by mounting the parts on a substrate at corresponding predetermined positions thereof. One or more kinds of substrates and at least one group of parts, to be mounted on the corresponding substrates, are introduced into the system lot by lot. The introduced parts on one or more previously prepared parts containers are placed so as to correspond to the substrates on which the individual parts are to be mounted, thereby providing one or more sets of the parts, each set corresponding to a respective one of the substrates. The sets of parts are supplied to a parts mounting station of the system.
