PAD GRID ARRAY AND A METHOD FOR PRODUCING SUCH A PAD GRID ARRAY

摘要

According to the invention, an electrically insulating substrate (S1) is provided with a plurality of longitudinally extended, elevated waves (W1) on the underside thereof. The conductor pattern is applied on the underside of the substrate by means of laser structuring such that the terminal pads (P1) are arranged in a flat manner in the grid array, and each is situated in the crest area of a wave. The inventive pad grid array can be produced with a fine grid of, for example, 250 νm.
