Soldering heatsink is designed to welding the fins on aluminum or copper base by environmental protection lead-free medium temperature soldering process. 

The fins can be folded fin, L-FIN, zipper fin, or fins with heat pipe, and the material is generally AL6063, AL6061, C1100, etc. 

According to the material, the soldering heat sink can be divided into aluminum solder heat sink, copper solder heatsink or welding heat sink copper, copper&aluminum composite soldering heat sink, zipper fin soldering heat sinks, heat pipe soldering heat sink.

According to the process, soldering heatsink can be divided into high temperature soldering and low temperature soldering. For high temperature soldering heat sink need 700-800 degrees to weld. Commonly used soldering process is low-temperature soldering, low-temperature welding heat sink temperature between 200-300 degrees, basically no deformation, can be process with high precision processing, can be used with any equipment.
