7、IGHT PERCENTAGE OF FLUX For most applications, a solder designated as 2.2% flux by weight is generally used. In other applications, where excessive amounts of resin may be undesirable, 1.1% flux by weight solder may be used. A 3.3% flux by weight solder may be specified when a larger amount of flux is required.
