Abstract
A multiple die is used to trim a plurality of electrical component leads, all at the same time, by using a die and a hydraulic press to develop a shearing action. Male and female die members each define a pattern of holes arrayed to mate with the configuration of leads extending from an electronic package. Near the upper face of the female die member, a plurality of tiny O-rings are mounted, one for each lead, encircling the paths for the leads as the package is positioned atop the die. The transverse relative motion between the male and female members of the die shears the leads while the O-rings serve to isolate and limit the amount of shock and vibration that can be transmitted along the leads.
