Solder Flux

　　The flux is one of the important factors of successful welding. Flux of this company is composed of high-purity chemical materials and is produced under strict quality control. It can remove the oxide and maintain the metal solder face clean with good lubrication to conduct good welding. Aiming at different operation methods and different requirements, multiple types of flux are equipped for alternative.

　　Product advantages:
　　• Excellent heat resistance can withstand multiple thermal cycles
　　• Good moisture resistance can protect the copper surface from producing oxidation for several months
　　• There is a very small number of ion contaminants, without residues or areas outside the copper surface
　　• It is chemically mild with low-temperature process, without anti-welding layer peeling, corrosion coating and other undesirable phenomena

Characteristics	The lead-free soldering flux is with no corrosion residue, evenly distributed in light-colored and is suitable for high-density, larger circuit boards. It needs to be cleaned after welding.	Lead-free solder with no-clean flux is a kind of RMA-type flux with high-solder joints, without joint welding and false welding, and is suitable for high-density hybrid circuit boards.	It is mainly used for the wire, transformer, coil, enameled wire or other original parts of the tin-plated pins. This product has no residue, but with bright feet, fast tin-coating and remains easy to climb after welding.	It is mainly used for the wire, transformer, coil, enameled wire or other original parts of the tin-plated pins. This product has no residue, no corrosion, but with bright feet, fast tin-coating and remains easy to climb and non-volatile after welding.	It is the cleaning-free leadless flux, belonging to the R-type and halogen-free flux. It has good infiltration ability and is suitable for high-density hybrid circuit boards, especially for the soldering of PCB boards of various small household appliances.	It is the cleaning-free leadless flux, belonging to the R-type and halogen-free flux, and is suitable for microelectronics, wireless assembly line welding and high-density hybrid circuit boards, especially for wave soldering of the motherboard, computer peripheral products.	It is mainly used for welding high-density hybrid circuit boards and components of severe oxidation. It has to be cleaned after welding.	It is a special flux and is suitable for soldering of stainless steel, aluminum and other materials.
