METHOD AND APPARATUS FOR AFFIXING SPHERES TO A FOIL MATRIX

摘要

An improved method of affixing spheres (4) to a foil matrix (2) is described herein. First, a cell sandwich (32) is prepared. This cell sandwich (32) includes spheres (4) mounted on a foil matrix (2) which are disposed between upper and lower pressure pads (34 and 36. The cell sandwich (32) is then heated (e.g.. to about 530.degree.C). The spheres (4) are then affixed to the foil matrix (2) by directing the all sandwich (32) through a roll press (48) which compresses the heated cell sandwich (32).
