Then remove (glue will be melted). (Fig. S-1-6) (1) Release the flat pack-IC from the CBA using twee- zers. (Fig. S-

11、1-6) Caution: 1. Do not supply hot air to the chip parts around the flat pack-IC for 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) 2. The flat pack-IC on the CBA is affixed with glue, so be careful

12、 not to break or damage the foil of each pin or the solder lands under the IC when removing it.

13、Fig. S-1-2 1-5 With Soldering Iron: (1)Using desoldering braid, remove the solder from all pins of the flat pack-IC. When you use solder flux which is applied to all pins of the flat pack-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 shar

14、p 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 is fixed with glue to the CBA; when removing entire flat pack-IC, first apply soldering iron to center of the f

(Fig. S-1-6) With Iron Wire: (1)Using desoldering braid, remove the solder from all pins of the flat pack-IC. When you use solder flux which is applied to all pins of t

16、he flat pack-IC, you can remove it easily. (Fig. S-1-3) (2)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 or hot air blower, pull up the wire as the solder melts so as to lift the IC leads from the CBA contact

18、s. (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 it may be damaged if force is applied. Flat Pack-IC Desoldering Braid Soldering Iron Fig. S-1-3 Fin

Installation (1)Using desoldering braid, remove the solder from the foil of each pin of the flat pack-IC on the

20、CBA so you can install a replacement flat pack-IC more easily. (2)The “I” 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 presolder the four corners of the flat pack-IC. (See Fig. S-1-8.) (3)Solder all pin

21、s of the flat pack-IC. Be sure that none of the pins have solder bridges. 1-3-4 Instructions for Handling Semi-conductors Electrostatic breakdown of the semi-conductors may occur due to a potential difference caused by electro- static charge during unpacking or repair work. 1. Ground for Human Body

22、Be sure to wear a grounding band (1M) that is prop- erly grounded to remove any static electricity that may be charged on the body. 2. Ground for Workbench (4) Be sure to place a conductive sheet or copper plate with proper grounding (1M) on the workbench or other surface, where the semi-conductors

23、are to be placed. Because the static electricity charge on clothing will not escape through the body ground- ing band, be careful to avoid contacting semi-con- ductors with your clothing.
