Static electricity can not be seen or touched, the voltage of several thousand volts in an instant may cause fatal damage to delicate and small electronic parts! The electrostatic protection must be meticulous and meticulous, and the grounding of the anti-static workbench becomes a top priority.
The anti-static workbench is basically made of metal material, and the countertop is made of anti-static mat or anti-static fireproof board, which has good grounding measures and excellent anti-static performance.
1. The principle is actually very simple. The anti-static workbench is based on the ordinary workbench of the user, and the anti-static function is added, that is, how to discharge the static electricity.
2, anti-static workbench countertops are generally made of anti-static melamine high-pressure decorative laminate commonly known as anti-static fireproof board as a surface material, combined with wood materials. The wood material is generally a particle board, which is grounded through a conductor such as a steel column and grounded through a grounding wire, so that the static electricity of the desktop is smoothly discharged to the earth through the connecting wire.
3. There are also some worktables that are made of stainless steel. The desktop needs to be covered with an anti-static table mat. The table mats are connected to the ground through a grounding wire to achieve the effect of discharging static electricity.
The point-to-point resistance test of the surface of the anti-static workbench should comply with the national electronic industry standard SJ/T10694-2006. When testing the static leakage resistance of the workbench, one electrode is in good contact with the table mat, and the other electrode (clip) is connected to the workbench ground wire (or wristband jack).
