导言
Adding silver to leaded solder paste can significantly improve its fluidity, enhance soldering reliability, and greatly optimize the low-impedance performance of solder joints after welding. Today, KEWEI factory introduces a moderately priced lead solder paste with good soldering performance: metal composition – Sn62.8/Pb36.8/Ag0.4.
Developed for the evolving SMT rapid chip soldering process, this no-clean solder paste exhibits minimal residue after welding, with the residues offering high insulation impedance performance. It fully meets the no-clean requirements of SMT chip mounting processes in electronics factories.
