YY Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 1C. Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 1C.
Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 1C in general, althoughTherefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 1C in general, although
the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of

[ Removing the DVD Deck ]
Before removing Pick Up PCB and DVD PCB connector, short circuit the position shown in Fig. 1 using
a soldering iron. If you remove the DVD Deck with no soldering, the Laser may be damaged.
[ Installing the DVD Deck ]
Remove all the soldering on the short circuit position after the connection of Pick Up PCB and DVD
PCB connector.
NOTE
DY Before your operation, please read OPREPARATION OF SERVICING� .
Y Use the Lead Free solder.
Y Manual soldering conditions
Y Soldering temperature: 320 ? 20uC
Y Soldering time: Within 3 seconds
Y Soldering combination: Sn-3.0Ag-0.5Cu
Y When Soldering/Removing of solder, use the draw in equipment over the Pick Up Unit to prevent the
Flux smoke from it.
