Patent ID: 7032305

Claim:
A method of mounting electrical component assemblies on opposite sides of a printed circuit card, said printed circuit card being provided with a plurality of through holes and having connection pads on a both sides, comprising: inserting a chock on a first side of the printed circuit card, said chock having a thickness about equal to a thickness of one of two electrical component assemblies to be mounted on said printed circuit card and said chock having a plurality of through holes that correspond to the plurality of through holes in said printed circuit card; inserting a standoff through each through hole in said printed circuit card and said chock and placing a spring around each standoff to be used to press said chock against said printed circuit card; pressing the chock against the printed circuit card; mounting a first electrical component assembly on a second side of the printed circuit card; placing a package tool having a plurality of springs on a horizontal support; placing the first electrical component assembly inside the package tool so that the springs of the package tool come into contact with the first electrical component assembly; removing the chock from the first side of said printed circuit card such that springs of the package tool exert a force that compensates for the weight of the first electrical component assembly inside the package tool; and mounting a second electrical component assembly on the first side of the printed circuit card.
