device.
• Disassemble the instruments in a static-free work area only.
• Use a conductive work area to dissipate static charge.
• Use a conductive wrist strap to dissipate static charge
accumulation.
• Minimize handling.
• Keep the replacement parts in original static-free packaging.
• Remove all plastics, styrofoams, vinyls, papers, and other
static-generating materials from the immediate work area.
• Use only antistatic solder extractor.
