The K&S 643 makes it possible to
bond chips to hybrid packages without
the risk of causing previously bonded
adjacent chips to float loose or cooking
film resistors until they change value. The
technique is to heat only a chip-size spot of
the substrate to eutectic temperature
instead of the whole substrate.
