Black Technology of Electronics Factory - Anti-static Wrist Strap Bracelet

If you just entered the electronics factory, you should have had contact with the training and explained the role of the anti-static wrist strap to prevent static electricity from breaking down parts and causing product malfunctions.

Of course, there are also some old employees who joke that most of the electronics factories are assembly line operations. Each person is in charge of a station and repeats the work for a long time. Run, the line leader in charge of the assembly line will switch on the 220-volt circuit to electrify him until he gives up and dare not have the idea of running anymore, so he can work with peace of mind.

But in fact, as the first training said, the purpose of wearing an anti-static wrist strap is to prevent the static electricity of the human body from breaking down parts, resulting in poor product function, resulting in various rework, etc., so it is necessary to wear an anti-static wrist strap.

The principle of anti-static wrist strap bracelet

The anti-static bracelet is made of a stainless steel shell that is close to the wrist, and is grounded by a wire and an iron clip through a 1MΩ resistance in the line. The purpose is not only to discharge the static electricity on the human body at any time, but also to prevent the sparks generated by the rapid discharge from causing damage to the electrostatic sensitive devices, and to play an isolation role.

Wired anti-static bracelet, which consists of a stainless steel case that fits tightly on the wrist, a 1MΩ resistor, and an alligator clip with wires. When in use, it is worn on the wrist like a watch, and the crocodile clip is clamped on the grounded metal on the production line, so that the static electricity generated by the human body leaks to the ground through the stainless steel shell of the bracelet, the 1MΩ resistance inside the bracelet and the crocodile clip wire, thereby avoiding the static electricity on the human hand from damaging those fragile components. When using the wired anti-static wristband, it is required that the wristband should be in close contact with the wrist, and the wire of the wristband should be well grounded, otherwise the anti-static effect may not be achieved.
