Kester part number 24-9574-7618 K100LD is a lead free solder wire featuring Tin 99.3 percent Copper 0.7 percent alloy composition with 275 Rosin Activated flux in a 0.031 inch diameter size. This professional grade solder excels in PCB assembly, electronics rework, through hole soldering, and precision repair applications where reliable joints and consistent performance are non negotiable. The no clean flux residue minimizes post solder cleanup, making it ideal for high volume production environments and meticulous hand soldering work alike. RoHS compliant and manufactured in the USA, this solder delivers the repeatability and quality that serious electronics professionals depend on for mission critical work.
Ultra fine sized diameter useful for precision soldering and micro electronics.
.015" (0.4 mm)
Very fine sized diameter useful for precision soldering and jobs requiring small amounts of solder.
.020" (0.5 mm)
Fine sized diameter used for through hole and and surface mount work. Delivers a Controlled amount of solder.
.025" (0.6 mm)
Ideal for standard circuit board components where precision is needed but not ultra-fine work.
