E. Electrostatic discharges from your hands or tools can cause permanent
damage to most of the semiconductor devices on the printed circuit card
assemblies. Obey the general precautions given below to prevent such
damages:
• Do the disassembly and assembly work on a grounded conductive surface.
• Put on a conductive wrist-strap that is grounded.
• Touch your tool to the ground (grounded metal structure, etc.) before
you use it.
• Use a tip-grounded soldering iron.

R7HRACFW06M or
R7HRACFW10M
(Panasonic)
(Refer to the right
for the vendor and
vendor part number)
· R7HRACFW06M: 0.6 mmÆ (0.024 in) wire and 500 g/roll
· R7HRACFW10M: 1.0 mmÆ (0.039 in) wire and 1 kg/roll.
You can also get the same lead-free solder from:
Senju Metal Industry Co., Ltd.
ECO-solder RMA98 SUPER P3 M705
0.6 or 1.0 mm (wire dia.).
Wire (C/A) Stranded copper wire (MIL-W-22759/34 or equivalent) with:
· Teflon insulation
· Temperature rating of 150°C or higher
· Voltage rating of 600 V or higher.
Use one of the sizes given below for repair of printed
conductors if such repair does not make the performance
unsatisfactory:
· No. 28 AWG or thicker for conductor width 0.02”
(0.5 mm) or less.
· No. 26 AWG or thicker for conductor width 0.02”
(0.5 mm) thru 0.08” (2 mm).
· No. 24 AWG or thicker for conductor width 0.08”
(2 mm) or more.
Ethyl Alcohol or
Isopropyl Alcohol
