How do you conduct an ESD test?
The testing conducted consists of applying one positive and one negative pulse to the component, allowing a 0.3 second interval between pulses. A set of devices is exposed to these pulses at a given voltage level and pin grounding combinations; the device is tested for full static and dynamic parameters.
How does an ESD mat work?
ESD or Static matting is designed to drain static discharge from items placed on its surface. The way it does this is by slowing down the flow of static charge, which neutralises the static electricity and moves the charge into the (grounded) mat, away from the electronic components being worked on.
Do ground bracelets work?
Operators should use an anti static wristband to ensure any static discharge has a way to go from themselves to the ground safely. Without wearing a wristband whilst working on a static sensitive device/component you could effectively transfer static discharge onto the item and cause significant damage.
How do you maintain an anti static wrist strap?
All wrist bands should be cleaned with a mild detergent on a periodic basis. Be sure that metallic expansion wrist bands are thoroughly dried to prevent corrosion. Woolite™ works well. Liquid detergents are better than dry in that there is less caking and frictional wear.
How do you ground an ESD workbench?

How do you know if grounding is working?
Insert one probe of the circuit tester into the small slot and the other probe into the large probe. If the circuit tester lights up, you have power to the outlet. Now place one probe in the small slot and the other probe into the “U” shaped ground hole. The indicator should light up if the outlet is grounded.
