Abstract
An oriented array of small, fragile electrical devices such as beam lead transistors or integrated circuits, partially embedded in wax, are removed from the wax and transferred to a releasable mounting without disrupting the orientation of the devices. The releasable mounting comprises a plate with a layer of silicone rubber or resin which exerts a suction or vacuum holding force on the array of oriented devices.
Claims4
Apparatus for releasably holding an oriented array of articles and for transferring the articles, which comprises:
- a mounting constructed of material that releasably holds the articles in position;
- a carrier for receiving the articles from the mounting, the carrier being constructed of material selected from the group consisting of silicone rubber and silicone resin, each of which exhibits pressure sensitive, vacuum holding properties of sufficient magnitude to hold the articles in the original orientation upon release of the articles from the mounting;
- and
- means for abutting the carrier against the articles on the mounting and for separating the carrier and the mounting to effect a transfer of the articles to the carrier upon release of the articles by the mounting.
In an apparatus for transferring an oriented array of articles from a releasable support onto a carrier, wherein the carrier is constructed of a pressure sensitive, vacuum holding material selected from the group consisting of silicone resin and silicone rubber and, wherein the articles are held by the carrier after the article support is released:
- a carrier supporting pedestal having a nonplanar surface wherein an interior portion is elevated relative to the peripheral portions thereof;
- means for holding said releasable support over said pedestal;
- and
- means for forcing said releasable support into pressure engagement with said carrier positioned on said pedestal to deform said carrier about the elevated portion of said pedestal sufficiently to uniformly distribute compressional forces to press said article against the pressure sensitive, vacuum holding carrier whereupon said carrier hold said articles in said oriented array and for discontinuing said pressure engagement between said releasable support and said carrier to transfer the oriented array to said carrier upon release of the articles from the releasable support.
