Handling Printed Circuit Boards
Some printed circuit boards are equipped with CMOS-type parts. They are sensitive to overvoltage.
Uncontrolled touch of PCBs can destroy those parts. Consider following precautions, to avoid accidental
damage:
1. Touch PCBs or parts only for repair purpose.
2. Before you start working on PCBs or parts discharge yourself be touching an earth connected part of the
enclosure.
3. Dismount PCBs only after mains supply is switched off, better disconnected.
4. Before removing PCBs disconnect cables.
5. Touch PCBs only at the edge.
6. Use only antistatic packaging material for transport and store.
7. Prevent touch of PCBs and highly insulating material like plastic foils or clothing made from synthetic fibers.
8. Deposit PCBs only on conductive base.
9. Care for earth connection to welding iron.
