The inspection criteria for PCBA circuit boards can be adjusted according to specific requirements and demands. Here are some common inspection criteria:
- Visual inspection: This includes checking the soldering quality, correct component installation and placement, presence of cracks, deformation, or damage on the circuit board.
- Functional testing: Conducting functional tests on the PCBA circuit board to ensure it operates normally according to design requirements. This involves checking if various functional modules on the circuit board work properly and verifying the accuracy of input and output signals.
- Electrical characteristic testing: Using appropriate testing equipment such as multimeters, oscilloscopes, etc., to measure electrical parameters on the PCBA circuit board. This includes checking if power supply voltage, current, resistance, capacitance, and other parameters are within specified ranges.
- Environmental testing: Conducting environmental adaptability tests on the PCBA circuit board to determine its performance stability under different environmental conditions. Examples include high temperature, low temperature, humidity, vibration, anti-interference tests, etc.
- Reliability testing: Subjecting the PCBA circuit board to reliability tests that simulate various operating conditions in real-world environments to assess its lifespan and reliability. This includes long-term operation tests, temperature cycling tests, vibration and shock tests, etc.
In summary, the inspection criteria for PCBA circuit boards should be determined based on specific product requirements and industry standards to ensure the quality and performance of the product meet the specified requirements.
