摘要： The transformation of An IC substrate with edge contacts into a ball grid array is accomplished using a flexible circuit that has terminals arranged planarly on the underside for receiving meltable solder humps and whose conductors leading outwardly from the terminals have exposed ends. The upper side of the flexible circuit is connected with the lower side of the substrate, whereupon the edge regions of the flexible circuit are bent up and around the substrate and the ends of the conductors are electrically contacted to the edge contacts of the substrate.

摘要： Two semiconductor memory chips are placed onto a flexible wiring and are shaped by simple folding of the flexible wiring about a central elastic line, into a space-efficient stack arrangement whose outer contacts are formed only at one marginal side. To form memory cards, a plurality of such stack arrangements can be placed onto a simply constructed printed board.

摘要： A process for the production of printed circuit boards having first zones of a wiring pattern for receiving solder and second sub-zones provided with solder rejecting properties so that they do not receive solder, characterized by galvanically applying a solderable etch-resistant metal layer on the first sub-zones of each conductive metal layer, by photo printing a mask of etch-resistant material on the second sub-zones, etching to remove the exposed portions of the conductive metal layer, removing the mask from the second sub-zones and providing the exposed second sub-zones with a solder rejecting property with the aid of passivation without impairing the solderability of the etch-resistant metal layers of the first sub-zones.
