Are you sure you're using an anti-static esd table?
People working in electronics factories often come into contact with anti-static tables, but how do you verify their anti-static function?
1. The surface resistance of the tabletop must meet anti-static esd requirements.
2. The surface resistance of the paint coating on the table must meet anti-static requirements.
3. The overall grounding resistance of the table must meet anti-static requirements (volume resistivity from the tabletop to the legs).
Test these in this order. Only if all tests meet the anti-static requirements can you say you're using an anti-static table. What exactly are the anti-static requirements? Learn more on the Ant Anti-static Mall website.
