With Soldering Iron: 1.Using desoldering braid, remove the solder from all pins of the flat pack-IC. When

5、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 to which solder will not adhere (iron wire). When heating the pins, use a fine tip soldering iron or a hot ai

(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

Installation 1.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-IC indicates pin 1. (See Fig. S-1-7.) Be sure this mark matches the pin 1 on th

12、e 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 Point Soldering Iron Iron Wire or Hot Air Blower Fig. S-1-5 Fine Tip Soldering I

Ground for Human Body Be 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 Workbench Be sure to place a conductive sheet or copper plate with proper

15、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.

P = Spring, L = Locking Tab, S = Screw, CN = Connector

18、* = Unhook, Unlock, Release, Unplug, or Desolder e.g. 2(S-2) = two Screws (S-2), 2(L-2) = two Locking Tabs (L-2) (5) Refer to “Reference Notes.” Reference Notes 1.CAUTION 1: Locking Tabs (L-1) and (L-2) are fragile. Be careful not to break them. 2.The BD Main CBA electrical components having such fe

19、atures are identified by the mark “#” in the schematic diagram and the parts list. Before replacing any of these components, read the parts list in this manual carefully. The use of substitute replacement parts that do not have the same safety characteristics as specified in the parts list may creat

20、e shock, fire, or other hazards. Notes: 1.Do not use the part number shown on these drawings for ordering. The correct part number is shown in the parts list, and may be slightly different or amended since these drawings were prepared. 2.All resistance values are indicated in ohms (K = 103, M = 106)

21、. 3.Resistor wattages are 1/4W or 1/6W unless otherwise specified. 4.All capacitance values are indicated in F (P = 10-6 F). 5.All voltages are DC voltages unless otherwise specified. 6.Electrical parts such as capacitors, connectors, diodes, ICs, transistors, resistors, switches, and fuses are iden

22、tified by four digits. The first two digits are not shown for each component. In each block of the diagram, there is a note such as shown below to indicate these abbreviated two digits. 1-11-2HTN_SC LIST OF CAUTION, NOTES, AND SYMBOLS USED IN THE SCHEMATIC DIAGRAMS ON THE FOLLOWING PAGES: 1. CAUTION

23、: FOR CONTINUED PROTECTION AGAINST FIRE HAZARD, REPLACE ONLY WITH THE SAME TYPE FUSE. ATTENTION: POUR UNE PROTECTION CONTINUE LES RISQES DINCELE NUTILISER QUE DES FUSIBLE DE MME TYPE. RISK OF FIRE-REPLACE FUSE AS MARKED. 2. CAUTION: Fixed Voltage (or Auto voltage selectable) power supply circuit is

24、used in this unit. If Main Fuse (F9000) is blown, first check to see that all components in the power supply circuit are not defective before you connect the AC plug to the AC power supply. Otherwise it may cause some components in the power supply circuit to fail. 3. Note: 1.Do not use the part num

25、ber shown on the drawings for ordering. The correct part number is shown in the parts list, and may be slightly different or amended since the drawings were prepared. 2.To maintain original function and reliability of repaired units, use only original replacement parts which are listed with their pa

26、rt numbers in the parts list section of the service manual. 4. Voltage indications for PLAY and STOP mode on the schematics are as shown below: A V F This symbol means fast operating fuse.
