Lead-free Soldering Paste(tin solder paste)Alloy Composition(welding paste alloy)Sn-3.5Ag \ Sn-0.7Cu \ Sn-Ag-Cu \ Sn-58BiLead-Contained Solder PasteAlloy CompositionSn63/Pb37 \ Sn62/Pb36/Ag2 \ Sn43/Pb43/Bi14 Sn10/Pb88/Ag2Basic concept and characteristic of Solder PasteSolder paste is a cream-like mixture of solder alloy powder and flux/vehicle system;Solder paste should be rheological, i.e., its viscosity will decrease under the action of shear stress to favor the printing process but recover afterward to help to fix the electronic components before reflow;During the reflow process, the flux system will remove the surface oxidation layer and then the molten solder alloy will wet and react with the component terminal and metal pad on PCB and finally form the mechanical and electrical joining.

Sorts of Solder PasteBy solder alloy composition, Pb-contained or Pb-free solder paste;By cleaning method, Rosin based, water soluble or no-clean solder paste;By flux type, Rosin, Rosin Medium Activated, Rosin Activated or Organic based solder paste;By applying method, solder paste for stencil printing, screen printing or syringe dispensing.
