What to do about static electricity in electronic products?
Modern digital products are becoming increasingly powerful, while circuit boards are getting smaller and more integrated. They all have interfaces for human-computer interaction, creating an ESD (electrostatic discharge) problem. Common ESD protection points in digital products include: USB ports, HDMI ports, IEEE 1394 ports, antenna ports, VGA ports, DVI ports, button circuits, SIM cards, headphone jacks, and other data transmission interfaces.
ESD can cause product malfunctions, crashes, and even damage, leading to other safety issues. Therefore, before products are released to the market, domestic and international testing agencies require electrostatic discharge and surge impact tests. Contact discharge needs to reach ±8kV, and air discharge needs to reach ±15kV, which places high demands on anti-static design.
