PCB proofing popularizes PCB short circuit inspection methods for you

1. The PCB manufacturer opens the PCB diagram on the computer, lights up the short-circuited network, and sees which place is closest to it, which is the easiest to connect to. Pay special attention to the short circuit inside the IC.

2. If PCB manufacturers use manual soldering, they must develop a good habit. First, check the PCB board visually before soldering, and use a multimeter to check whether the key circuits (especially the power supply and ground) are short-circuited; secondly, solder one at a time For the chip, use a multimeter to check whether the power supply and the ground are short-circuited; in addition, do not throw the soldering iron randomly when soldering.

1. Open the PCB diagram on the computer, light up the short-circuited network, and see which place is closest to it. It is most likely to be connected. Pay special attention to the short circuit inside the IC.

2. If it is manual soldering, develop a good habit. First, check the PCB board visually before soldering, and use a multimeter to check whether the key circuits (especially the power supply and ground) are short-circuited; secondly, each time a chip is soldered Use a multimeter to check whether the power supply and ground are short-circuited; in addition, do not throw the soldering iron randomly when soldering. If you throw the solder onto the solder feet of the chip (especially surface mount components), it will not be easy to find.
