There is a lead solder paste Welding Sn63Pb37 Tin paste Smt solder paste LED solder paste

No-clean solder paste uses polymer film former, modified resin, organic active agent and high molecular alcohol ether solvent

  Highly reliable flux with high quality, high sphericity, uniform distribution of powder particles, low oxygen content of Sn63/Pb37

  It is refined from alloy powder and has excellent rheology. It has good printing moldability and is not easy to collapse. The flux activity is moderate and the weldability is good.

  It can effectively match various lead-containing solders and is an ideal no-clean solder paste for soldering with lead soldering.

The flux system is scientifically selected and developed according to the welding mechanism, which can effectively reduce the free energy of the solder and reduce the surface tension.

  Improve the fluidity and solderability of the molten solder.

  It has excellent continuous printing property, especially suitable for fine pitch printing, good off-molding moldability, strong adhesion and easy to collapse.

  The reflow process window is wide, and excellent soldering results can be achieved in a wide reflow soldering temperature zone.

  Excellent solderability, full solder on the solder joints, bright, strong tin-transparent, low soldering failure rate.

  Residual residue after welding, uniform spreading, not easy to absorb moisture, no cleaning, excellent ICT test performance, surface insulation

  High resistance and reliable electrical performance.

This product can be used with surface-treated PCBs such as bare copper, gold-plated, and tin-plated plates, and various other lead-based solder alloy components.

  In computer motherboards, mobile phones, MP3, MP4, communication equipment, audio and video equipment, refrigeration equipment, vehicle equipment, instrumentation, medical

  Widely used in equipment and other high reliability, high quality electronic appliances
