Components are not naturally grown on PCBs but are connected to the circuit board through soldering technology, which uses high temperature and solder to firmly connect the component pins together to achieve electrical and mechanical connections.
The comparison between THT and SMT technologies highlights their distinct advantages and applications in PCB assembly. While THT offers reliability and accessibility, particularly for larger components, SMT excels in space utilization and automation, making it ideal for modern, high-volume manufacturing.
Wave soldering, introduced in 1956, automated PCB assembly for through-hole components, reducing defects and costs. The process includes flux application, preheating, double wave soldering, and rapid cooling for reliability. Its efficiency and precision make it crucial in modern electronics.

In the PCBA processing industry, we use wave soldering and reflow soldering to solder components. However, when encountering PCBA boards that require double-sided assembly of through-hole components, it is more beneficial to use double-sided wave soldering.
Single Phase Wave Soldering Machine is an advanced equipment used in through-hole assembly that allows for stable and continuous output of molten solder, resulting in higher quality soldering. This machine is widely praised by PCBA manufacturers for its ability to reduce costs, improve efficiency, and avoid common soldering issues.
