Repairing Circuit Cards
4.6
To protect ESDs during repair, take the following precautions:
•
The workbench must be earth-grounded, and the work surface must be
covered with an antistatic or static dissipative material bonded to the
bench (bolt). A field service kit (PN 126-3442-010) or equivalent can be
used if an adequate workbench is not available.
•
Repair technicians must wear a wrist strap of 250 kilohms to
2 megohms that contacts the repair technician's skin and the bolt
bonding the covering to the bench or safety ground. The wrist strap
must be connected before parts are removed from packaging.
•
All electrical equipment must be grounded using a 3-wire power cord.
•
Clothing must not touch the device under repair.
•
ESDs are delivered with protective packing (containers or conductive
foam). The devices should remain in their original containers until
needed.
•
Containers with ESDs must contact the antistatic work surface, and
the wrist strap must be connected before parts are removed from
packaging. Devices must be handled by their bodies. Leads must be
contacted only when necessary.
•
Test setups must have correct voltage polarity.
•
Volt Ohm Milliamp (VOM)-type meters must not be used to measure
resistance; they can damage devices.
•
Only antistatic (metallized) desoldering tools should be used.
4.7
ESDs are protected when properly packaged in conductive or
antistatic packaging. Acceptable packaging is marked as either conductive or
antistatic.
