1). Gold or aluminium wires are welded to the aluminium contacts
on the chip and to the glass feed-through, pins of the header.
2). TAB (Tape Automated Bonding). The contacts on the chip
have a gold dot.
A pretinned felxible printed circuit is directly soldered to these
gold dots and the other end to a PC-board, or the header.
TAB printed circuit, however, holds the sensor in place itself.
