PCB Technical - What is wave soldering?

Wave soldering refers to the process of spraying molten soft solder (lead-tin alloy) through an electric or electromagnetic pump into the designed solder wave, allowing pre-installed printed boards with components to pass through the solder wave and achieve mechanical and electrical connection between component solder end or pins and printed board solder pads. The solder used in wave soldering mainly consists of tin bars, which allow the molten liquid tin to be soldered onto the solder pad of the circuit board where the components are inserted. This involves soldering the component pins to the circuit board.

Wave soldering is a common surface mount technology used to solder electronic components onto printed circuit boards. It is achieved by placing components in appropriate positions on a pre-coated PCB with solder paste and then transporting them to the heating area through a conveyor belt. In the heating area, the PCB uses a solder wave to make the solder come into contact with the component pins and form solder joints.

The advantages of wave soldering

1. High degree of automation: Wave soldering is a highly automated welding process that can quickly and effectively complete welding tasks and improve production efficiency.

2. Suitable for large-scale production: Due to its high automation and fast welding speed, wave soldering is very suitable for large-scale electronic product production.

3. Suitable for various components: Wave soldering can be applied to different types of electronic components, including plugins and surface mount components.

4. Lower welding costs: The automation and efficiency of wave soldering make its costs relatively low, making it more cost-effective in mass production.
