What is the difference in structure of anti-static grid curtain and anti-static rubber mat
The anti-static grid curtain is printed with black conductive ink on a transparent PVC film with good anti-static effect, so that the grid surface of the anti-static grid curtain has better conductivity.
Anti-static table mats are mainly made of static-conductive materials, static-dissipative materials, and synthetic rubber through various processes. The product is generally a two-layer structure, the surface layer is a static dissipative layer, and the bottom layer is a conductive layer. The table mat lasts for a long time, has good anti-acid, anti-alkali, anti-chemical flux characteristics, and is wear-resistant and easy to clean.
Anti-static table mats are mainly made of anti-static (conductive) static materials and static dissipative materials such as synthetic rubber. The surface layer is about 0.5 mm thick dissipative static layer, and the bottom layer is about 1.5 mm thick conductive layer. Commonly used is a 2mm double-layer composite structure, available in green, gray, blue, black, yellow, etc. *Surface resistivity: 106-109Ω *Bottom resistivity: 103-105Ω
To eliminate static electricity hazards, production workshops and advanced laboratories in the microelectronics industry such as electronic semiconductor devices, electronic computers, electronic communication equipment, and integrated circuits need to be laid with anti-static table mats or conductive floor mats. After laying and grounding, the working surface will discharge the static electricity of the human body, so that the ESD tweezers, tools, instruments, etc. that the human body contacts with the table surface reach a substantially uniform potential, so that the electrostatic sensitive device (SSD) is not subject to electrostatic discharge phenomena such as friction and electrification. The interference of the wide step surface band, so as to achieve the effect of electrostatic protection.
