Static charges
Clothing of non-electrostatic material should be worn. Clothes made of material like
wool, silk or synthetic fibres can give very high static voltages and should therefore
NOT be worn.
After the MOS circuits have been mounted on the board proper handling precautions
should still be observed. Until the sub-assemblies are inserted into a complete
system in which the proper voltages are supplied, the board is no more than an
extension of the leads of the devices mounted on the board. To prevent static
charges from being transmitted through the board wiring to the device it is
recommended that conductive clip or conductive tape is put on the circuit board
terminals.
Transient voltages
To prevent permanent damage due to transient voltages, do not insert or remove
MOS devices, or printed-circuit boards with MOS devices, from test sockets or
systems with power on.
Voltage surges
Beware of voltage surges due to switching electrical equipment on or off, relays and
D.C. lines.
