Abstract

A pallet (work holder) has been historically designed and built for each new product in order to build the product in our front end factories, i.e. the factory area where components are assembled onto a printed circuit board. These pallets have been cus- tom made for each new PCB and incorporate fea- tures of location, clamping and origin. The pallet is registered precisely for placement of components at each assembly station. This is accomplished using tooling holes located at the side of the pallet, or using the leading edge of the pallet. The registra- tion of the origin is normally specific for each assem- bly station and does not change. Each time the printed circuit board has been changed, the pallet was also changed and/or reworked to accommodate the new geometries or changed component place- ments During the prototyping process of a new pal- let, changes to the PCB occur quite frequently, incur- ring high costs and extended product development and manufacture.
