Hand tools

Non electrical hand tools:

Hand tools are high risk for two reasons firstly they often come in direct contact with ESDS and secondly they often contain isolated conductors. Where tools are static dissipative they are safer because a charge is dissipated through the handle to ground.

The best way of finding out what hand tools are used is to check the tool boxes in the production and rework areas. Among hand tools are tweezers, pliers, cutters, screwdrivers, nut drivers, rulers and brushes but operators often have tools that you will never think of.

Hand tools should be replaced with tools that use static dissipative handles. As hand tool wear out and get mislayed new ESD safe tools can be phased in over time.

A dissipative handle on a conductive tool does eliminate the risk of charged tool discharges into a device. It will not help where the ESD event comes from a charged device (CDM) or a charged board (CBM). The mass of most conductive small tools will be enough to dissipative a charge even if the tool is grounded through a dissipative handle.
