Selective wave soldering is a localised soldering technique

Selective wave soldering is a localised soldering technique that forms a wave peak in specific areas to solder only the pins of components that require soldering. This soldering method offers high flexibility and precision, enabling efficient soldering of individual or small quantities of components. It is particularly suitable for circuit boards with high mix and low volume production. Selective wave soldering applies solder only to the areas that need to be connected without damaging the original electronic components, effectively avoiding thermal effects on surrounding components and improving soldering quality and reliability.

Applications of selective wave soldering:

High-precision soldering requirements: Selective wave soldering can precisely adjust parameters such as soldering temperature, time, and flow rate for each soldering point according to the requirements of the soldering object, achieving high-precision soldering.

Welding of specific areas: Selective wave soldering is suitable for welding specific areas, such as complex components or parts requiring high-precision welding.

Small-batch production and welding of specific components: Selective wave soldering is more suitable for small-batch production and welding of specific components, such as circuit board repair and assembly.

Material savings: Selective wave soldering reduces the use of flux and solder, as only the soldering area comes into contact with the solder.

It minimises solder residue and ionic contamination, enhancing the cleanliness of the circuit board.

Avoids thermal shock: Selective wave soldering does not subject the entire circuit board to thermal shock, thereby preventing defects that may arise from thermal shock.
