We know that the contact and friction between the human body and various objects can easily generate static electricity. During the SMT process, if you do not wear an electrostatic bracelet to contact the components, in addition to the human body may be slightly uncomfortable, the components The device is also easily damaged by static electricity. So the question is, how to detect whether there is static electricity? Let's take a look at the following Sanjing belts.

In general, we use SMT static detection equipment to detect whether there is static electricity, such as electrostatic potentiometers, megohmmeters, wristband detectors, etc., to detect static electricity at regular intervals. In addition to detecting static electricity, we must also do static protection. Let’s take a brief look at electrostatic protection.

To put the electrostatic protection work in place, the first thing we have to do is to establish a strict and complete SMT electrostatic control process, implement it from design, procurement, production technology, packaging, storage and transportation, and post eye-catching electrostatic protection signs. Good regular training on electrostatic protection.

In addition to the above requirements, 1. Do not touch sensitive components or components without good grounding;

2. Circuit boards with ICs must be handled on an anti-static workbench. If the ICs are not on an anti-static workbench, they must be stored in a grounded shielded container;

3. All instruments and equipment must be grounded, and wrist straps and shoe covers should also be tested daily to ensure that they meet the requirements of anti-static;

4. Do not place static insulating materials arbitrarily in the SMT anti-static safety zone, and use fixed-point ion wind eliminators in the process that may generate SMT static electricity.

The above is about SMT static detection and protection, I hope it can be helpful to everyone!
