YF-H-4258 Lead-free low-temperature no-clean solder paste, which is made by mixing low-oxidation tin powder with imported rosin and high-efficiency active agent in a vacuum environment. When the solder paste is reflowed, the activity can be slowly released, and the solder melts and has good fluidity and strong wettability. This solder paste can be used for heat-resistant modules, LEDs and other products that are not resistant to high temperatures.
YF-H-4258 does not contain any halogens. Although the halogen is excluded from the formulation, the breakthrough formulation design still has excellent soldering performance. After reflow, the solder joints are bright and full, no blackening, the residue is colorless, transparent, non-corrosive, and has the highest safety performance in the industry. .
YF-H-4258 has a wide reflow window, can adapt to a variety of reflow curves, stable viscosity, and good coating performance.
