Disassembly and Repair

Electrostatic Discharge (ESD) Precautions

Almost all electrical components can be damaged by electrostatic discharge
(ESD) during handling. Component damage can occur at electrostatic discharge
voltages as low as 50 volts.
The following guidelines will help prevent ESD damage when servicing the
instrument or one of the plug-in modules.
– Disassembly the instrument only in a static-free work area.
– Use a conductive work area to dissipate any static charge.
– Use a conductive wrist strap to dissipate static charge accumulation.
– Minimize handling.
– Keep replacement parts in their original static-free packaging.
– Remove all plastic, foam, vinyl, paper, and other static-generating materials
– Use only anti-static solder suckers.

Surface Mount Repair

Surface mount components should only be removed using soldering irons or
desoldering stations expressly designed for surface mount components. Use of
conventional solder removal equipment will almost always results in permanent
damage to the printed circuit board.

Tools Required

The following tools are required for basic disassembly.
– T20 Torx driver
– 3/16" nut driver (for rear panel connectors)
– 9/32" nut driver (for GP-IB connector)
– #2 Pozidrive (for fan)
