Be sure this mark matches the 1on the PCB when positioning for installation. Thenpresolder the four corners of the flat pack-IC. (SeeFig. S-1-8.)(3) Solder all pins of the flat pack-IC. Be sure that noneof the pins have solder bridges.Instructions for HandlingSemi-conductorsElectrostatic breakdown of the semi-conductors mayoccur due to a potential difference caused by electro-static charge during unpacking or repair work.1. Ground for Human BodyBe sure to wear a grounding band (1MΩ) that is prop-erly grounded to remove any static electricity that maybe charged on the body.2. Ground for Workbench(4) Be sure to place a conductive sheet or copper platewith proper grounding (1MΩ) on the workbench orother surface, where the semi-conductors are to beplaced. Because the static electricity charge onclothing will not escape through the body groundingband, be careful to avoid contacting semi-conduc-tors with your clothing.Example :Pin 1 of the Flat Pack-ICis indicated by a " " mark.Fig. S-1-7PresolderCBAFlat Pack-ICFig. S-1-8CBA< Incorrect >CBAGrounding BandConductive Sheet orCopper Plate1MΩ1MΩ< Correct >www. xiaoyu163. comQQ 376315150 992894298TEL 13942296513 992894298051513673QQTEL 13942296513 QQ 376315150 892498299TEL 13942296513 QQ 376315150 892498299http://www.xiaoyu163.comhttp://www.xiaoyu163.com
