There are parts which use the insulation

material such as a tube or tape for safety, or

which are assembled in the condition that

these do not contact with the printed board.

The inside wiring is designed not to get closer

to the pyrogenic parts and high voltage parts.

Therefore, put these parts in the original

positions.

Please include the following informations when you order parts. (Particularly the VERSION LETTER.)

1. MODEL NUMBER and VERSION LETTER

The MODEL NUMBER can be found on the back of each product and the VERSION LETTER can be

found at the end of the SERIAL NUMBER.

2. PART NO. and DESCRIPTION

You can find it in your SERVICE MANUAL.

When you exchange IC and Transistor with a heat sink, apply silicon grease (YG6260M) on the contact

section of the heat sink. Before applying new silicon grease, remove all the old silicon grease.

(Old grease may cause damage to the IC and Transistor).

ABOUT LEAD FREE SOLDER (PbF)

Distinction of PbF PCB:

PCBs (manufactured) using lead free solder will have a PbF printing on the PCB.

(Please refer to figures.)

Caution:

• Pb free solder has a higher melting point than standard solder;

Typically the melting point is 86

F~104

F(30

C~40

C) higher.

Please use a soldering iron with temperature control and adjust it to 650

F ± 20

F (350

C ± 10

C).

In case of using high temperature soldering iron, please be careful not to heat too long.

•

Pb free solder will tend to splash when heated too high (about 1100

F/ 600

C).

•

Pb free solder will tend to splash when heated too high (about 1100

F/ 600

C).

• All products with the printed circuit board with PbF printing must be serviced with lead free solder.

When soldering or unsoldering, completely remove all of the solder from the pins or solder area,

and be sure to heat the soldering points with the lead free solder until it melts sufficiently.

Recommendations

Recommended lead free solder composition is Sn-3.0Ag-0.5Cu.
