Causes and Countermeasures of Broken Circuits
With the development of technology, the circuit plays an important role in various electronic devices, but the broken circuit is easy to cause serious consequences, and it has become a problem that needs to be faced by many electronic equipment manufacturers. This article mainly discusses the causes and countermeasures of the circuit fracture, so as to eliminate the impact of broken circuits to the maximum extent.
Firstly, let’s talk about the causes of broken circuits. In general, when the current passes through the circuit, due to the resistance of the material to the current, the temperature of the circuit increases, and the temperature is too high, the circuit will break. In addition, due to the aging of the material and the oxidation, the poor contact between the circuit board and the connection lines may cause poor current conduction, resulting in burning of the circuit board. Moreover, improper circuit design, poor PCB design and poor wiring will cause circuit failure and cause broken circuits.
Secondly, let’s discuss the countermeasures of broken circuit. The most effective way to prevent broken circuits is to strengthen circuit design. On the one hand, pay attention to the choice of materials, choose materials with low temperature resistance, good conductor, and oxidation resistance. On the other hand, pay attention to the design of the circuit, not only consider the heat transfer performance of the circuit, but also consider the heat dissipation, so as to avoid the temperature of the circuit too high and cause fracture. In addition, attention should be paid to the quality of welding lines, so as to avoid poor contact between the circuit board and connection lines, and strengthen the design of PCB board, so as to reduce the increase of resistance caused by poor design and avoid circuit breakage.
To sum up, broken circuits are very common in various electronic devices, and the causes and prevention measures should be paid attention to. In order to eliminate the impact of broken circuits to the greatest extent, manufacturers need to pay attention to circuit design, material selection, welding process and PCB design, etc., in order to ensure the high quality of electronic equipment. With the efforts of all parties, the problem of broken circuits can be alleviated and the service life of electronic equipment can be improved.
