NOTES ON SOLDERING
� For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit. Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs accompanied by reworking of soldering. � Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 ºC. Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 ºC 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 soldering iron. Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting temperatures (hard to melt/easy to harden).
WHEN REPLACING DVD DECK
WHEN REPLACING DVD DECK
[ 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 � Use the Lead Free solder. � Manual soldering conditions � Soldering temperature: 320 ± 20�C � Soldering time: Within 3 seconds � Soldering combination: Sn-3.0Ag-0.5Cu � When Soldering/Removing of solder, use the draw in equipment over the Pick Up Unit to prevent the Flux smoke from it.
