Anti-static handling guidelines
Make sure that electro-static handling precautions are taken immediately before handling
PCBs and other static sensitive components
Before handling any static-sensitive items, operators should get rid of any electrostatic charge
by touching a sound safety earth, such as a radiator. Always handle PCBs by their sides and
avoid touching any components. PCBs should be stored in a clean, dry place that is free from
vibration, dust and excessive heat.
Storing the PCBs in a suitable cardboard box will also guard them against mechanical
damage.
