For China pcb manufacturer, what are the PCBA inspection equipment?

After completing the front-end soldering process, China pcb manufacturer cannot ensure that the PCBA board is intact. To ensure that the products shipped to the customer are intact and to improve customer satisfaction,it’s necessary to proceed inspection.

China pcb manufacturers’ testing equipment mainly includes: solder paste thickness gauge, AOI optical detector, X-ray detector, ICT, FCT, aging test rack, etc.

1.Solder paste thickness gauge

The solder paste thickness gauge uses laser to perform three-dimensional scanning, and the thickness distribution, area and volume distribution of the solder paste on the circuit board are measured in sections, which can effectively control the quality of solder paste printing.

2.AOI optical detector AOI automatically scans the PCB through the camera, collects images, and compares the tested solder joints with the qualified parameters in the database. After image processing, it can detect defects such as multi-tin, less tin, continuous tin, erection, less parts, direction, etc.

3.X-ray detector

The X-ray detector uses low-energy X-rays to quickly detect the object without damaging the item being inspected. A board with a BGA chip is usually used.

4. ICT

ICT is an automatic online tester with a wide range of applications and simple operation. ICT automatic online detector is mainly for production craft control, which can measure resistance, capacitance, inductance and integrated circuit. It is particularly effective for detecting open circuit, short circuit, component damage, etc., fault location is accurate, and maintenance is convenient.

5. FCT

The FCT functional test is to provide simulated operating environment such as excitation and load to the PCBA board. The state parameters of the board can be obtained to check whether the performance parameters of the board are consistent with the designer's requirements.

6. Aging test rack

The aging test refers to the process of simulating the product under the conditions of the actual usage conditions to carry out the corresponding conditions to strengthen the experiment. The long-term power-on test can be carried out according to the PCBA board of the electronic product to simulate the customer's usage and test the input/output to ensure that its performance meets the market demand.

The above is an important testing device for China pcb manufacturer the PCBA processing process and is a necessary device to improve the quality of the PCBA board.
