Abstract

PURPOSE: To prevent short-circuitting and opening due to positional displacement by providing a lower surface with a plurality of positioning pads each being greater than a connection pad in its area.
CONSTITUTION: A pad 4 is provided on the lower surface of a chip carrier 1 and a positioning pad 2 is provided at four corners, and further the area of the positioning pad 2 is formed to be greater than the area of the pad 4. For this, a preliminary solder for the positioning pad 2 is made higher than a preliminary solder 5a of the pad 4. Then, the tip end of positioning pad 2 of the chip carrier 1 is superimposed so as to ride on a conductor circuit 6 of a substrate 7. Thereupon, it becomes unnecessary to position the preliminary solder 5a of the pad 4 of the chip carrier 1 with the conductor circuit 8.
