When the flat pack-IC is removed from the CBA, handle it gently because it may be damaged if force is applied. 2. Installation 1.Using desoldering

20、braid, remove the solder from the foil of each pin of the flat pack-IC on the CBA so you can install a replacement flat pack-IC more easily. 2.The “” mark on the flat pack-IC indicates pin 1. (See Fig. S-1-7.) Be sure this mark matches the 1 on the PCB when positioning for installation. Then presold
