ABSTRACT:
A method of manufacturing a series of leadframe strip carriers, the individual members of the series having common external dimensions to facilitate production handling equipment setup and internal slot dimensions which vary to accommodate the various widths of available leadframe strips. This new method of manufacturing leadframe strip carriers results in a much lower unit cost, as compared to carriers manufactured from aluminum extrusions. This has been achieved using an injection molding process employing a single mold which produces constant length, width and height dimensions throughout the series, and which has an internal form die, the position of which can be varied with spacing inserts that can be either removed or transferred to the other side of the mold cavity as the mold is modified for progressively-narrower leadframe strips. To ensure durability, highly-abrasion resistant, fiber-reinforced plastic material is used to create the carriers. Although the carriers could be molded as an integral unit, mold construction is greatly simplified by molding two identical halves and bonding them together. In order to simplify manufacturing of the carriers, end cap grooves are molded at both ends.
