What are the two parts of the esd suit test?
Dust-free clothing is also called anti-static clothing and clean clothing. Anti-static is an important feature of dust-free clothing, especially in microelectronics and other industries, which have stricter anti-static performance requirements for clothing. The general test has two parts: surface resistance test and friction voltage test.
1. Surface resistance test
Principle: This test can verify the conductive efficacy of the conductive thread and whether the previous stitching process between the fabric and the fabric meets the requirements, such as the connection between the conductive threads.
2. Friction voltage test
Principle: This test is mainly to verify whether the cloth itself can reach a specified stable value in a short period of time after accumulating some voltage through friction.
