...
Antistatic tubes, bins, conductive foams
Plastics with conductive material
Place PCB in static-shielding bag before/after use
Avoid using torn or punctured static-shielding bags
2) Cover unused connectors with antistatic materials when not in use
3) Clothing/Area:
Antistatic footwear
Grounded table, floor mats
Antistatic wristbands
Antistatic footwear
4) Avoid tools with plastic handles:
- Handle
Portable Field Service Grounding Kit, like 3M Kit #8501 or #8507 consists of portable mat and wristband https://www.itm.com/product/scs-8501-static-dissipative-field-service-kit-standard-0-021
4) Things to avoid during handling:
Tools with plastic handles, since handle can get charged due to triboelectric effect
Letting boards/components come in contact with clothing, since static charges on fabrics can’t be dissipated with normal grounding
Moving PCBs unnecessarily
Coming into contact with the connectors and components
Letting chargeable plastics, like binders, within 0.6m of unshielded PCBs
Letting PCBs come within 0.3m of a computer monitor
5) Use a soldering iron with a tip that has proper ground connection:
...
Discharges atmospheric floating charges to ground
Provides protection against static electricity build up due to dry air
Maintain a relative humidity level between 20% and 80% non-condensing
PCB Design:
1) Clean and low impedance ground:
...
These are connected at critical points in the circuit, between input and output pins to ground
Kept close to terminals
Clamp voltage to a safe value based on the rating
To suppress ESD transients, place a ferrite bead on the input lead and connect a low value capacitor from the input lead to ground. LC at input filters the energy in the ESD transient to ground.
