Open circuit/short circuit electrical testing-深圳市海博精密电路有限公司

We all know that PCB (printed circuit board) is an important component of many electronic devices, and the performance and reliability of PCB largely depend on its electrical integrity. Therefore, in the PCB production process, open/short circuit electrical testing is essential to ensure that all PCBs meet the required specifications before delivery to customers.

Open/short circuit electrical testing can detect any defects or inconsistencies in PCB wiring, which may lead to subsequent performance issues or safety hazards. Therefore, electrical testing is crucial for PCB production and must be executed accurately to ensure the production of high-quality PCBs that meet all requirements.

Electrical testing requires the use of specialized testing machines or fixtures. Firstly, the PCB must be connected to the testing machine, and then voltage must be applied and the current monitored for any abnormalities. Then the test results should be recorded, as this information is very useful for future PCB inspections.

At Haibo, we use two electrical tests to detect open/short circuits. The first type is suitable for prototype flying needle testing, and the second type is nail bed testing. These two testing methods each have their own advantages and disadvantages, as shown below:
