Flux-Cored Solder Wire
Low Carbonizing Lead-Free Flux-Cored Solder Wire
The flux-cored solder wire enables fast soldering with less carbonizing of soldering tips and less flux spatter providing greater productivity than existing products.
Tip Carbonizing Test
Left : SN100C 030 (13sec. later)
Right : Conventional product (3sec. later)
Reduced flux spattering
SN100C (031) is a general purpose flux-cored lead-free solder wire that offers improved productivity. The alloy and cored flux combination provides excellent wetting for components with poor solderability.solder wire provides fast wetting, resulting in faster soldering.
Flux Spattering Test
Solder each wire with a tip temperature of 280℃ to 380℃.
Count the number of spattered flux droplets around each soldered wire.
Flux Spattering Test Result
Dramatic reduction in Flux spattering
Improved flux activity and durability
With sustained activity and good separation of the solder from the tip with a consequent reduced incidence of icicles, high reliability SN100C (551CT) is Ideal for sequential soldering and rework.
Incidence of Icicles
Left : Previous product (Icicles occur in 1 second heating)
Right : 551CT (Icicles do not occur)
*551CT occurs Icicles in 4 seconds heating
