Method to solve PCBA virtual soldering
Methods to solve PCBA virtual soldering:
The question should be: Is there any good way to easily find the PCBA solder joints?
⑴ Judge the approximate fault range according to the fault phenomenon.
⑵ Observe the appearance, focusing on the larger components and the components with large heat.
⑶ Observe with magnifying glass.
⑷ Pull the circuit board
⑸ Shake the suspicious component by hand, and observe whether the solder joints of its pins are loose.
