Are there minimum requirements when testing anti-static wrist straps?
There are no pre-specified minimum requirements when testing an anti-static wrist strap, but a very good experience is: every time you wear an anti-static wrist strap or start another job, test it. The frequency of the test depends on The ESD-sensitive equipment you are trying to protect. If the equipment is expensive and controlled by an operator, frequent monitoring is necessary, but if the equipment is not particularly sensitive and relatively inexpensive, then regular testing is sufficient.
There are a few things you should check when testing an anti-static wristband: make sure that the wristband is in close contact with your wrist; conductive fibers or metal/conductive substances are close to the skin; the snap on the metal buckle is suitable, and the snap on the coil end The connector should be tightly fastened, the spring of the banana plug has good elasticity, and it is in close contact with the plug hole of the banana plug. Other things that should be checked are: intermittent interruptions in the coil (usually at the end), dirt, oil and welding in the belt The outer shell (this will reduce the conductivity of the strap), it is safe to apply 1-5 pounds of tension to the snap button on the metal buckle in the coil.
