PCB Assembly How To Check The Connection?

- Aug 11, 2017-

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.

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 detect the poor wiring.

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.
