<p>PURPOSE:To facilitate the inspection of an integrated circuit chip and to enhance the mechanical strength of a connection part by electrically connecting connection wiring held to a state cut from the midway part thereof at the time of the mounting of the integrated circuit chip after the inspection of the integrated circuit chip. CONSTITUTION:A CPU 16 and an LED driver 17 are connected through seven connection wirings 43... and the connection wirings 43... are respectively cut from the midway parts thereof. The functions of the CPU 16 and the LED driver 17 are inspected in such a state that the connection wirings 43... are cut. After the completion of inspection, the cut parts 45... of the connection wirings 43... are electrically connected with solder 44 and a film carrier 41 is incorporated in a punching machine along a breaking line 42. Since the CPU 16 and the LED driver 17 are held by one continuous printed wiring board 12 and the wiring connection parts fixed by the solder 44 are positioned on the printed wiring board 12, mechanical strength is enhanced.</p> |
