ESD risk in the use of tweezers
ESD Tweezers are often used tools in the electronics industry. However, do you know the ESD risks caused by different tweezers during use?
There are many types of commonly used tweezers, and the common ones are shown in Figure 2:
We choose one of them for the test. As shown in Figure 3, the holding part and the tip are made of stainless steel and the resistance is less than 1000 ohms, and then the chip is applied with a static voltage of about 1000V through the CPM device.
When the tweezers touched the chip, the 5 lights on the ESD detector were all on (as shown in Figure 4). At this time, an ESD event greater than 200V occurred, and the voltage on the tweezers was released instantaneously, so the tweezers have an ESD risk.
