In addition to safety, other parts and assemblies are specified for conformance with regulations applying to spurious radiation. These must also be replaced

17、only with specified replacements. Examples: RF converters, RF cables, noise blocking capacitors, and noise blocking filters, etc.C. Use specified internal wiring.

Clearance DistanceWhen replacing primary circuit components, confirm specified clearance distance (d) and (d) between soldered terminals, and between terminals and surrounding metallic parts. (See Fig. 1)Table 1: Ratings for selected areaNote:This table is unofficial

23、 and for reference only. Be sure to confirm the precise values.2. Leakage Current TestConfirm the specified (or lower) leakage current between B (earth ground, power cord plug prongs) and externally exposed accessible parts (RF terminals, antenna terminals, video and audio input and output terminals

24、, microphone jacks, earphone jacks, etc.) is lower than or equal to the specified value in the table below.Measuring Method (Power ON):Insert load Z between B (earth ground, power cord plug prongs) and exposed accessible parts. Use an AC voltmeter to measure across the terminals of load Z. See Fig.

29、lat Pack-IC1. RemovalWith Hot-Air Flat Pack-IC Desoldering Machine:1.Prepare the hot-air flat pack-IC desoldering machine, then apply hot air to the Flat Pack-IC (about 5 to 6 seconds). (Fig. S-1-1)2.Remove the flat pack-IC with tweezers while applying the hot air.3.Bottom of the flat pack-IC is fix

30、ed with glue to the CBA; when removing entire flat pack-IC, first apply soldering iron to center of the flat pack-IC and heat up. Then remove (glue will be melted). (Fig. S-1-6)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.

31、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 for over 6 seconds because damage to the chip parts may occur. Put masking tape around the flat pack-IC to protect other parts f

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 sharp pin or wire

34、 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 flat pack-IC and

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.Affix the wire to a workbench or solid mounting point, as shown in Fig. S-1-5.3

37、.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 pads as shown in Fig. S-1-5.4.Bottom of the flat pack-IC is fixed with glue to the CBA; when removing entire flat pack-IC, first apply solde

38、ring iron to center of the flat pack-IC and heat up. Then remove (glue will be melted). (Fig. S-1-6)5.Release the flat pack-IC from the CBA using tweezers. (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-

39、IC is removed from the CBA, handle it gently because it may be damaged if force is applied.2. Installation1.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 “ I ” mark on the flat pack-

40、IC indicates pin 1. (See Fig. S-1-7.) Be sure this mark matches the pin 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 pins of the flat pack-IC. Be sure that none of the pins have solder bridges.To Solid Mounting Poi
