BGA funnel

U.S. Patent Number: 5381641

Abstract: A BGA funnel adapted for facilitating the loading of BGA packages into a BGA tube includes an rectangularly-shaped housing (16) and a roofing plate (18). The housing member has a loading end (28), an intermediate portion (19), and an unloading end (30). The intermediate portion of the housing member has a central bore (20) of a substantially U-shaped cross-section extending therethrough. The housing member includes a flat bottom portion (22) and a pair of short vertically extending side walls (24, 26) disposed integrally on each side of the bottom portion. An inwardly tapered channel (38) is formed between the side walls and extends between the loading end and the intermediate portion for receiving the BGA package to be inserted into the BGA tube. Narrow step portions (40, 42) are associated with the inwardly tapered channel for supporting only two side edges of the BGA package so that the bottom surface thereof is suspended freely above the top surface of the inwardly tapered channel. An outwardly tapered channel (50) is formed between the side walls and extends between the intermediate portion and the unloading end. The outwardly tapered channel is adapted for receiving a loading end of the BGA tube. The roofing plate is fixedly secured to the intermediate portion of the housing member so as to prevent the BGA package from being displaced out of the bore.
