Selective Wave Soldering Machine Technology

I. The characteristics of selective wave soldering machine technology

1. Precise control

Selective wave soldering technology avoids over-soldering or bridging problems unavoidable in traditional wave soldering by precisely controlling the soldering area.

2. High reliability

Selective wave soldering adopts computer control, which can precisely adjust the soldering parameters, such as solder temperature, wave height and transfer speed, to ensure the consistency and reliability of solder joint quality.

3. Energy saving and environmental protection

Selective wave soldering technology only heats and welds the area to be soldered, reducing solder waste and energy consumption. At the same time, the precise welding process reduces the rate of welding defects, reduces rework and scrap rate, with significant energy saving and environmental protection advantages.

II. The process flow of selective wave soldering machine

1. Pre-board processing

Before selective wave soldering, the PCBA needs to be cleaned and pre-coated flux. Cleaning can remove dust and oxides on the PCB to ensure good soldering wetting. The choice of flux and coating method will directly affect the soldering quality.

2. Preheating

Through preheating, the PCB and components can be heated to the appropriate temperature to reduce thermal shock during the soldering process to avoid component damage. Preheating temperature and time need to be adjusted according to the specific PCB and component type.

3. Wave soldering

Wave soldering is the core process of selective wave soldering. By controlling the temperature of the solder and the height of the wave, the solder is precisely applied to the area to be soldered. The soldering process ensures that the solder completely covers the pads and pins to form a reliable solder joint. The soldering parameters are optimized for the specific solder and PCB design.

4. Post-soldering cleaning and testing

After the completion of soldering, the PCBA needs to be cleaned to remove residual flux and slag. Subsequently, the quality of the solder joint inspection, including visual inspection, automatic optical inspection (AOI) and X-ray inspection. Through testing, to ensure that each solder joint meets the quality requirements to avoid welding defects.

III. The advantages of selective wave soldering technology

1. Improve production efficiency

Selective wave soldering technology can realize automated production, reducing the time and labor intensity of manual operation. Through the optimization of welding parameters, can significantly improve production efficiency, to meet the needs of mass production.

2. Reduce production costs

Selective wave soldering technology can reduce solder waste and rework costs. The precise welding process reduces the rate of welding defects, reducing rework and scrap. Overall reduced production costs and improved economic efficiency.

3. Adaptation to complex designs

Selective wave soldering technology can be adapted to complex PCB designs, especially the coexistence of through-hole components and surface mount components in mixed assembly boards. By precisely controlling the soldering area, high quality soldering can be realized to meet the needs of complex designs.

4. Improved Product Quality

Selective wave soldering technology can significantly improve product quality and reliability through precise soldering control and strict quality inspection.
