Abstract
A magnetic bubble memory packaging tool comprising a stationary base having a bias magnet replaceable mounting arm which cooperates with a moveable bias magnet replaceable mounting arm on a moveable base, the latter being coupled to move relative to said stationary base by a spring biased screw arrangement. With the bias magnets positioned on opposite sides of the mounting arms and with the yoke positioned to a compass the arms, and the bias magnets, rotation of the screw increases the bias of the spring urging the arms and magnets in a direction away from each other and into engagement with the inside walls of the yoke. The spring bias is a measure of the pressure with which the bias magnets engage the yoke for bonding and the screw is calibrated so as to select the bias of the spring. The mounting arms are replaceable to accommodate bias magnets of different dimensions for different bubble memory packages and also disclosed are positioning tools for precisely locating the bias magnets and yoke on the mounting arms.
