Abstract
A leadless chip carrier is attached to a printed circuit board by soldering its input-output connections to the printed circuit board and also by providing an adhesive between a central portion of the leadless chip carrier and the printed circuit board. This adhesive provides increased mechanical strength to the connection, improving its tolerance to temperature cycling. The adhesive used may be the same solder used to make the input-output connections.
