PCB Chinese name for printed circuit board, also known as printed wiring Board, is an important electronic components, is the support of electronic components, electronic components are the carrier of electrical connection. Because it is produced by electronic printing, it is called "printed" circuit board. The PCB develops from single layer to double sided, multi-layer and flexible, and still maintains the development trend of each. Due to the continuous development of high-precision, high-density and high reliability direction, and continuously reduce the volume, reduce costs, improve performance, making the PCB in the future of electronic equipment development projects, still maintain a strong vitality.Medical PCB Assembly
PCB assembly is a relatively fine work, in the whole process, there will be a lot of special requirements, we not only to check whether the correct wiring, operation is in line with the norms, there are some minor precautions, and the inspection schematic diagram is also a key link. So how do we check the connection?
1, according to the circuit diagram to check the installation of the line, according to the wiring, in accordance with a certain order to check the installed line.Medical PCB Assembly
2, according to the actual line control schematic diagram, take the component as the center to check the line. The connection of each component pin is checked once, check each to be in the circuit diagram existence. In order to prevent errors, the lines that have been checked usually should be marked on the circuit diagram, it is best to carry out the relevant test, direct measurement of the component pins, so as to be able to detect the bad wiring.Medical PCB Assembly
3, when a circuit board assembly welding, and then check whether it can work normally, usually not directly to the circuit board power supply, but to follow the steps to ensure that every step is no problem after the electricity is not too late.Medical PCB Assembly
