Types of PCB Soldering Methods There are several methods used for PCB soldering, each with its advantages and suitable applications. The most common methods include: Through-Hole Soldering Through-hole soldering is the traditional method of attaching components to a PCB. In this method, the component leads are inserted through drilled holes in the board and soldered onto the opposite side. This method provides strong mechanical connections and is suitable for larger components or those subjected to Read more…

What is Wave Soldering? Wave soldering is a traditional soldering method that has been widely used in the electronics industry for decades. It involves passing the PCB over a molten solder wave, allowing the solder to come into contact with the exposed leads and pads on the board. The solder then solidifies, creating a strong electrical and mechanical connection between the components and the PCB. The Wave Soldering Process The wave soldering process typically consists Read more…
