Then remove (glue will be melted). (Fig. S-1-6

6、)4. Release the flat pack-IC from the CBA using tweezers. (Fig. S-1-6)CAUTION:1. The Flat Pack-IC shape may differ by models. Use an appropriate hot-air flat pack-IC desoldering machine, whose shape matches that of the Flat Pack-IC.2. Do not supply hot air to the chip parts around the flat pack-IC f

7、or over 6 seconds because damage to the chip parts may occur. Put masking tape around the flat pack-IC to protect other parts from damage. (Fig. S-1-2)3. The flat pack-IC on the CBA is affixed with glue, so be careful not to break or damage the foil of each pin or the solder lands under the IC when

9、k-IC, you can remove it easily. (Fig. S-1-3)2. Lift each lead of the flat pack-IC upward one by one, using a sharp pin or wire to which solder will not adhere (iron wire). When heating the pins, use a fine tip soldering iron or a hot air desoldering machine. (Fig. S-1-4)3. Bottom of the flat pack-IC

Affix the wire to a workbench or solid mounting point, as shown in Fig. S-1-5.3. While heating the pins using a fine tip soldering iron

12、 or hot air blower, pull up the wire as the solder melts so as to lift the IC leads from the CBA contact pads as shown in Fig. S-1-5.4.

(Fig. S-1-6)Note: When using a soldering iron, care must be taken to ensure that the flat pack-IC is not being held by glue. When the flat pack-IC is removed from the CBA, handle it gently because

Installation1

15、. Using desoldering 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 instal

16、lation. Then presolder the four corners of the flat pack-IC. (See Fig. S-1-8.)3. Solder all pins of the flat pack-IC. Be sure that none of the pins have solder bridges.Instructions for Handling Semi-conductorsElectrostatic breakdown of the semi-conductors may occur due to a potential difference caus

17、ed by electrostatic charge during unpacking or repair work.1. Ground for Human BodyBe sure to wear a grounding band (1 M) that is properly grounded to remove any static electricity that may be charged on the body.2. Ground for WorkbenchBe sure to place a conductive sheet or copper plate with proper

18、grounding (1 M) on the workbench or other surface, where the semi-conductors are to be placed. Because the static electricity charge on clothing will not escape through the body grounding band, be careful to avoid contacting semi-conductors with your clothing.Example :Pin 1 of the Flat Pack-ICis ind
