1. SERVICE PRECAUTIONS

1.1 SERVICE PRECAUTIONS

A

1.You should conform to the regulations govering the product (safety, radio and noise, and other regulations), and should keep the safety during servicing by following the safety instructions described in this manual.

2.Be careful about an internal sharp edge.

3.Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by

electrostatic induction.

4. Be careful in handing made from metal parts. There might be burr at the edge of it.

Therefore, for lead-free soldering, the tip temperaturewinautoof soldering iron must be set to around 373 C in general, although

 

 

 

 

 

 

1.2 NOTES ON SOLDERING

 

 

For environmental protection, lead-free solder s used on the printed circuit boards mounted in this unit.

D

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 C.

 

 

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).

The following lead-free solders are available as service parts:

E Parts numbers of lead-free solder: GYP1006 1.0 in dia.

GYP1007 0.6 in dia. GYP1008 0.3 in dia.
