In the industry standard of anti-static workbenches, surface resistance and grounding resistance are two crucial parameters, which play key roles in preventing electrostatic accumulation and protecting sensitive electronic components and equipment. The following is an in-depth analysis of the key roles of these two parameters:

First, the key role of surface resistance

Prevent electrostatic accumulation:

The surface resistance of the anti-static workbench is one of the important indicators to measure its anti-static performance. The size of the surface resistance directly affects the accumulation and dissipation speed of static charges on the workbench surface.

According to the industry standard, the surface resistance of the desktop of the anti-static workbench should be controlled within a certain range, usually between 10^6 Ω and 10^9 Ω. This range can not only prevent the rapid accumulation of static charges but also ensure that the static charges dissipate within an appropriate time, thereby avoiding damage to sensitive electronic components and equipment.

Protect sensitive electronic components:

In high-precision and high-requirement industries such as electronic manufacturing, medicine, and chemical engineering, static electricity may cause product quality degradation, equipment damage, and even safety accidents. The proper control of the surface resistance of the anti-static workbench can effectively reduce the impact of static electricity on sensitive electronic components and protect the quality of the product and the normal operation of the equipment.

Improve production efficiency:

Static electricity interference may cause problems such as equipment malfunction and production interruption, affecting production efficiency. By controlling the surface resistance of the anti-static workbench, static electricity interference can be reduced, and the stability and production efficiency of the production line can be improved.

Second, the key role of grounding resistance

Ensure the timely export of static electricity:

The grounding resistance refers to the resistance value between the anti-static workbench and the earth. Its size directly affects whether the static charges can be imported into the earth in a timely and effective manner.

According to the industry standard, the grounding resistance of the anti-static workbench should be less than a certain value (such as 100 Ω or lower) to ensure that the static charges can be exported quickly and prevent electrostatic accumulation from causing damage to products and equipment.

Protect the safety of equipment and personnel:

Electrostatic discharge is one of the main forms of electrostatic hazards, which may cause equipment damage, fires, and even personnel injuries. By maintaining a low grounding resistance, it can ensure that the charges can be discharged to the earth quickly during electrostatic discharge, thereby protecting the safety of equipment and personnel.

Improve the anti-static effect:

The reduction of grounding resistance helps to enhance the overall anti-static effect of the anti-static workbench. When the grounding resistance is too large, the static charges may not be exported in time, resulting in the anti-static workbench losing its due effect. Therefore, maintaining a low grounding resistance is the key to ensuring the effective operation of the anti-static workbench.

Conclusion

The surface resistance and grounding resistance of the anti-static workbench play indispensable roles in preventing electrostatic accumulation and protecting sensitive electronic components and equipment. By controlling these two parameters within a reasonable range, the anti-static effect of the workbench can be significantly improved, and the stability of the production line and product quality can be guaranteed. Therefore, when designing and manufacturing the anti-static workbench, industry standard requirements should be strictly followed to ensure that the surface resistance and grounding resistance are within the specified range. At the same time, these two parameters should also be inspected and maintained regularly during use to ensure their long-term effectiveness.
