Wave soldering refers to the melting of molten solder (lead-tin alloy), electrical pump or electromagnetic pump into the design requirements of the solder peak, can also be formed by injecting nitrogen into the solder pool, so that pre-installed components The printed board achieves the soldering of the mechanical and electrical connections between the component's soldered ends or the leads and the printed circuit board's solder bumps.

Wave soldering process: insert components into corresponding component holes → pre-coating flux → preheat (temperature 90-100°C, length 1-1.2m) → wave soldering (220-240°C) cooling → remove excess card foot → check .

The reflow process relies on remelting the paste solder pre-dispensed on the PCB pad to achieve soldering of the surface-mounted component solder tails or the mechanical and electrical connections between the leads and the PCB lands. .

Wave soldering has a new welding process with people's awareness of environmental protection. In the past, tin-lead alloys were used, but lead was a heavy metal that caused great harm to the human body. This led to a lead-free process that used * tin-silver-copper alloy* and a special flux, and required a higher preheating temperature for the soldering temperature.

The use of perforated (TH) or hybrid technology boards, such as televisions, home audio equipment, and digital set-top boxes, is still used in most products that do not require miniaturization and high power. weld. From a process point of view, wave soldering machines can provide only a few of the most basic equipment operating parameters.
