How can the circuit board effectively prevent static interference?
Inspection Notes? do not use a multimeter to detect electrostatic discharge sensitive devices, lead terminals, or corresponding wires. If you need to guard such detection; in the detection, should be in direct contact with the ground test pen on the electrostatic.From the requirements of ESD protection, when the circuit boards such as MOS devices are pulled out or inserted, the following operations shall not be allowed in the case of power on.The device for detecting circuit boards must be reliably grounded.
Transportation noteWhen storing and transmitting circuit boards, electrostatic packaging materials such as metallized plastic bags and metal boxes must be used.? if the container itself does not conduct electricity, the circuit board must be wrapped in conductive material such as conductive foam, electrostatic discharge, plastic bags, aluminum foil or paper, and no ordinary plastic bag or film can be used under any circumstances.
Notice of useA basic rule is that these boards can be touched by hand only when necessary. Pay attention to the employee's gestures when touching, and do not touch the pin or conductor of the circuit board.When handling circuit boards, all work stations and packing cases must be reliably grounded. Before contacting the circuit board, the personnel concerned must ensure that he does not carry excessive static electricity. The simplest way to release static electricity is to contact the grounding parts of some equipment (such as the metal frame of the electric cabinet, water pipes, etc.) before touching the circuit board.? most plastic materials are extremely easy to generate static electricity, so they must be as far away from the circuit board as possible.The circuit board should not be placed in the environment of insulating material or material which is easy to produce static electricity (plastic film, insulating mesa and synthetic material, etc.). Must be placed on the conductive surface of the object (electrostatic discharge table, conductive foam materials, static discharge plastic bag, static discharge box).
