ABSTRACT:
A device that brings a vertically falling integrated circuit to a rapid, bounce-free stop at a test site includes a set of relatively lightweight blades arrayed next to the fall path with their faces in a mutually spaced relationship. At its upper end, each blade is pivotally and loosely mounted on an energy absorbing elastomeric sleeve. At its lower end, each blade carries a stop member that projects into the fall path when the blade is in a first ("test") position. The stop members are generally aligned with one another horizontally across the fall path to define a stop surface that precisely locates an integrated circuit at the test site. The device includes an arrangement for repeatedly drawing the lower ends of the blades in unison to a second ("release") position where the stop members are clear of the fall path.
