While there are many reasons why PCB circuit boards malfunction, the next Kingsheng PCBA processing manufacturers introduced a way for precisely identifying the issue and swiftly resolving it: PCB circuit board fault detection.

One of the most important components in the electronic industry is the printed circuit board (PCB). It is essential to electronic equipment because it connects different electronic components electrically and mechanically. As long as integrated circuits and other electronic components are available, PCBs are utilized in practically every type of electronic equipment, including computers, communication devices, smart phones, electronic watches, and military weapon systems. The advancement of semiconductor technology and integrated circuits has allowed parts of electronic devices to become minuscule in size. The PCBs that hold these components are getting smaller, more sensitive, and more sophisticated. To satisfy client standards, they must be produced at a high standard.

Printed circuit board (PCB) flaws include things like improper component placement, bad soldering, improper circuit design, or physical damage. These mistakes may cause electronic equipment to malfunction or fail, necessitating expensive repairs or replacements. Debugging PCB problems, which entails finding and fixing any mistakes or flaws in the PCB design or manufacturing process, is therefore crucial to guaranteeing the quality, dependability, and efficiency of electronic goods.

First, carefully observe the surface of the faulty circuit board for obvious signs of failure. Such as: whether the scorched burning integrated IC Or other components, the circuit board is broken traces of break.

Understand the process of fault occurrence, analyze the reason of the fault and infer the possible parts of faulty device.

To understand and analyze the nature of the application of fault circuit board, statistics used in the type of integrated IC.According to the location of various types of integrated IC, the size of the possibility of failure to sort.

Using a variety of detection methods, according to the probability of the order of detection in order to gradually narrow the scope of failure.

Determine the specific fault device, the replacement of a good integrated IC, it is best to first install a IC device socket to try.

If the installation test is still not normal, it should be tested again until all the faults on the faulty circuit board are overhauled.

Circuit board repair matters needing attention.

When you get the faulty circuit board to be repaired, you should first ask the user the entire equipment fault phenomenon and ask the user how to locate the circuit board, for example: whether the user replaces the same good circuit board, whether the equipment has been tested Check the program has a clear error code of the circuit board and so on. This is the beginning of an analytical study in maintenance.
