How To Solve PCBA Short Circuit Problem Quickly

How To Solve PCBA Short Circuit Problem Quickly

In PCBA manual welding processing, short circuit is a more common poor processing, in order to achieve the same effect of manual welding and machine stickers, short circuit is a problem that must be solved. PCBA short circuit is a very common problem in PCBA processing. When there is a short circuit problem, only a timely and rapid solution to the problem can ensure that the quality of the product meets the requirements.


Quick Solution To PCBA Short Circuit Problem

Use the short-circuit positioning analyzer.

Light the short-circuit network on the , find the place where the circuit board is most tolerant of short-circuiting, and pay attention to the IC internal short circuit. 

If there is a batch of the same short circuit in SMT small batch processing, you can take a board to cut line operation, and then each part is energized to check the short circuit part. 

Small size PCB processing surface capacitor welding must be careful, especially the power filter capacitor (103 or 104), the number is large, it is easy to cause short circuit between the power supply and the ground. 

Manual welding operation to develop a good habit, use a multimeter to check whether the key circuit is short circuit, each time after manual processing of an IC need to use a multimeter to measure whether the power supply and ground short circuit. 

If there is a BGA chip, because all the solder joints are invisible and covered by the chip, and it is a multi-layer board (more than 4 layers), it is best to split the power supply of each chip at the time of design, and connect it with a magnetic bead or 0 ohmresistance, so that when the power supply and the ground short circuit, disconnect the magnetic bead detection, and it is easy to locate a chip.

The above is about the quick solution to the PCBA short circuit problem, Shenzhen Kingford Technology Co., Ltd. specializes in providing overall PCBA electronic manufacturing services, including upstream electronic component procurement to PCB production and processing, SMT, DIP plug-in, PCBA testing, finished product assembly and other one-stop services.
