FAST TURN PCB is a circuit maker specializing in PCB manufacturing and assembly, with excellent and quick turn PCB fabrication and circuit card assembly capabilities.

The five main testing projects of PCBA

Under normal circumstances, PCBA testing is placed at the end of the processing process to check the integrity of PCBA products. Testing must be strictly carried out in accordance with regulations to improve the accuracy of testing and thus improve the quality of PCBA factory shipments. Testing mainly involves testing the functionality, power calibration, lifespan, performance, and other data of PCB products.

1. ICT testing
This test is mainly aimed at PCB circuit boards and components, with a relatively small application range. Moreover, the equipment is relatively expensive and often only used in high-end products. Its main functions include circuit on/off, voltage and current values and fluctuation curves, amplitude, noise, etc.

2. FCT testing
After the completion of PCBA production, it is necessary to burn the program of the product into the IC, and then conduct functional simulation testing on the finished product. This step is FCT testing, which can timely detect problems in hardware and software. And provide feedback to customers for software optimization and hardware issue improvement. This test is a must-have for PCBA factories.

3. Fatigue testing
As the name suggests, fatigue testing is a test of the durability of PCBA, to see how long the circuit board can withstand use without failure. This test is usually conducted by sampling from the same batch. After high-frequency and long-term operation, the probability and proportion of faults are detected, and this parameter is used to determine the quantity ratio of fatigue.

4. Aging test
The main purpose of this test is to keep the product powered on and working continuously for a fixed period of time, and observe for any failures or malfunctions. Strict product control requires passing aging tests before mass production can proceed.

5. Extreme operating condition testing
This type of test is not commonly used and is mainly applied to products that may encounter harsh working conditions, such as military, off-road vehicles, and special equipment. The test content includes the limit values of temperature, humidity, drop, splashing, and vibration.
