PCBA processing electrostatic protection measures and precautions
In the process of PCBA processing, electrostatic protection is crucial. In the PCBA processing and production, electrostatic protection can effectively protect electronic components and ensure the quality of the patch. Then, how to do electrostatic protection measures in the PCBA processing and production? The following PCBA processing manufacturer kinhford Electronics to explain to you. First, why should PCBA processing do electrostatic protection?
There are precision electronic components on the PCBA board, and many components are more sensitive to voltage. A shock above the rated voltage will damage these components.https://www.kingfordpcb.com/yuan.php?time=1685694568
The PCBA board damaged by static electricity is difficult to gradually investigate during functional testing. What is more fatal is that some PCBA boards function normally during testing, but when the finished products are used in the hands of customers, there are occasional defects, which brings great hidden dangers to the after-sales service and affects the company's brand and reputation. Therefore, in the PCBA processing process, we must attach great importance to ESD electrostatic protection.
Second, PCBA processing how to do electrostatic protection measures
(1) The operator must wear electrostatic work clothes, it is forbidden to attach or wear any metal products on the work clothes, and it is not allowed to take off the work clothes on the site of the operation of electrostatic sensitive products. The buttons of the work clothes must be all buttoned up, and it should not be in a state of undressing as far as possible. 2) Wear an ESD wrist strap that is in good contact with your skin and grounded reliably. Do not store electrostatic objects such as plastic boxes, erasers, cardboard, and glass on the ESD safety workbench.(3) The operation of all components must be carried out on the electrostatic safety workbench. Components entering the ESD work area must be treated according to the ESD requirements.
(4) The electrostatic sensitive components that fall on the floor during the operation must be tested and reconfirmed before they can be used. Items that cannot be directly tested must be confirmed before they can be released.(5) When holding the sensitive element, avoid touching its lead and connector. Avoid the area of electrostatic sensitive components when holding the mainboard. When some components are to be cleaned, anti-static brushes should be used, and plastic brushes should not be used.
