What brand of soldering flux is of better quality?
The United States ITW Chemtronics this brand is not bad, there are two agents at home level
Good east Xintai suggest you see your solder welding what products, wire / transformer / inductor with DXT-126A flux, PCB plate with 398A solder flux, tinned copper with DXT-128A for oxidation and solder.
Qualified flux is not good or bad, qualified flux is only suitable or not. Welding process, equipment, PCB (circuit board) quality, component quality, solder quality (tin content), operation staff proficiency are not the same, the choice of flux and requirements are also different.1, wave soldering should be selected for wave soldering flux, hand dip is another.2, using special flux spray coating process should be selected; using the process of hand dip coating is used spray type; foaming is another kind of.3, PCB, and the degree of oxidation of components is different, should be equipped with different activities of the strength of the flux.4, the purity of solder is different (tin content), should be equipped with different active strength of soldering flux.5, operation staff proficiency also determines the choice of soldering flux.Without proper selection of suitable flux, that is, the soldering flux can not achieve the best welding effect, and then the flux can only play the role of general flux.
