When PCB circuit board maintenance need to pay attention to what? Dongguan Rocket PCB circuit board manufacturers and share PCB circuit boards need to pay attention to the points for attention during the maintenance. PCB circuit boards with the continuous development of electronic products, all kinds of equipment failure frequency is greatly increased, the demand for maintenance personnel are also rising, especially for just getting into the circuit board maintenance personnel, a lot of people to start all don't know how to start, also don't know how to study, really want to learn good circuit board maintenance, you must have a certain number of electricity, electricity. PCB circuit boards principle of the graph is a blueprint, can realize the function of circuit users need. PCB circuit board design is mainly refers to the design of the landscape, need internal electronic components, metal wire, the layout of the hole is connected with external crosstalk, electromagnetic protection, heat dissipation, and other factors. Circuit board PCB circuit board maintenance need for fast, medium speed and low logic circuit, placed close to the connector, and logic and memory, the principle should be placed on the connector. In this way, to reduce total impedance coupling, radiation and the decrease of the cross. What are the precautions for PCB circuit board repair? 1。 Maintenance, first is to do a good job of anti-static, such as wear anti-static work clothes and shoes, wear good anti-static wrist strap. Maintenance of workbench also want good anti-static processing, such as adding antistatic mesa. 2. Pay attention to safety, including PCB and electrical maintenance to take into account the PCB maximum capacity. 3. When need to contact with high voltage must pay attention to safety, do a good job in heavy current prevention measures.
