Wave soldering is suitable for mass production and multi-layer PCB board welding. It realizes welding by immersing the PCB board into the solder wave, which has the advantages of high automation and fast welding speed.

3. Hot Air Soldering

1. Temperature control

2. Time control

3. Soldering speed

1. Updating equipment

2. Do a good job of equipment maintenance

Automatic Optical Inspection (AOI) technology is adopted to carry out comprehensive inspection of PCB boards after welding. Through the high-resolution image recognition technology, detect the welding quality, timely detection and repair of welding defects, improve product quality.

2. X-ray inspection

For some precision components and difficult to directly detect the welding point, you can use X-ray inspection technology. Through X-ray fluoroscopy, the connection and quality of the welding points are detected to ensure that the welding quality meets the standard requirements.

1) Stencil printing: Solder unavailability, insufficient or excessive solder, solder misalignment, bridging, stain, scratch etc.

2) Component defect: missing or excessive component, misalignment, uneven, edging, opposite mounting, wrong or bad component etc.

3) DIP: Missing parts, damage parts, offset, skew, inversion, etc

4) Soldering defect: Excessive or missing solder, empty soldering, bridging, solder ball, IC NG ,copper stain etc.
