[ When the removal of the DVD Deck ]
Before removing Pick Up PCB and DVD PCB connector, make the short circuit on the position as
shown Fig. 1 using a soldering. If you remove the DVD Deck with no soldering, the Laser may be
damaged.
[ When the installation of 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 Pb Free solder and the exclusive soldering iron.
• 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 drawing equipment over the Pick Up Unit to prevent the
Flux smoke from it.
The laser diode used for a pickup head may be destroyed with external static electricity.
Moreover, even if it is operating normally after repair, when static electricity discharge is
received at the time of repair, a life of product may become short.
Please perform the following measure against static electricity, be careful of destruction of a
laser diode enough at the time of repair, and work.
• It works on the desk which performed measures against static electricity, such as conductive
mat.
• Soldering iron with ground wire or ceramic type is used.
• A worker needs to use a ground conductive wrist strap for body.
