PCB circuit board maintenance need to pay attention to the three matters

PCB circuit board With the continuous development of electronic products, a variety of equipment failure greatly increased the frequency of maintenance personnel requirements are also rising, especially for just contact with the circuit board maintenance personnel, many people do not start at the beginning Know how to start, do not know how to learn, in fact, want to learn PCB circuit board maintenance must have a certain number of electricity, mold basis.

PCB circuit board schematic diagram for the blueprint, to achieve the circuit users need to function.PCB circuit board design is mainly the layout of the design, the need for internal electronic components, metal wiring, through-hole and external connection layout, electromagnetic protection, heat Dissipation, crosstalk and other factors.

Circuit board manufacturers need not know fast, medium speed, vulgar logic circuit, placed in close proximity to the connector range, while the vulgar logic and memory should be placed in the principle of the connector range. In this way, is it beneficial to reduce common impedance coupling, radiation and crosstalk? Of the PCB circuit board maintenance considerations which the following simple to explain the circuit board maintenance Note:

1, before the first maintenance to do anti-static work, such as wearing anti-static overalls and shoes, wearing a good anti-static wrist strap. Maintenance of the workstations have to do anti-static treatment, such as anti-static countertops.

2, pay attention to electricity safety, including the circuit board power maintenance to take into account the maximum capacity of the circuit board.

3, when the need to contact the strong power must pay attention to personal safety, good anti-power measures.
