1、 The difference between PCBA testing and PCBA testing

In the PCBA manufacturing process, inspection and testing are two key steps, but their goals and methods are different:

1. PCBA inspection

Definition: Testing mainly focuses on the physical appearance, structural integrity, welding quality, etc. of PCBA to ensure compliance with manufacturing standards.

● Method:

AOI (Automatic Optical Inspection): Identify solder joints and component positions correctly through cameras.

X-Ray inspection: used for internal structural inspection of hidden solder joints such as BGA and QFN.

SPI (Solder Paste Inspection): Check the printing quality of solder paste to avoid poor soldering.

Visual Inspection: Manual inspection of appearance defects.   

2. PCBA Testing

Definition: Testing focuses on functional verification to ensure that the PCBA can function properly and meet design requirements after being powered on.

● Method:

FCT (Functional Testing): Simulate a real working environment to test circuit functionality.

ICT (Online Testing): Testing circuit continuity and component parameters through needle beds.

○ Aging test: Run the PCBA for a long time to verify stability.

Environmental testing (such as temperature, humidity, vibration testing) ensures reliability.

2、 Technical differences in PCBA inspection and testing

1. Inspection focuses more on "manufacturing defects", such as poor solder joints, component offset, insufficient solder paste, etc.

2. Testing focuses more on "functional issues" such as circuit short circuits, signal abnormalities, and excessive power consumption.

3. Testing is usually carried out during the SMT/DIP stage, while testing is conducted after assembly is completed.
