less dross,no clean Solder paste(Sn63Pb37) for metal weling

Solder paste(Sn63Pb37) is 1.containing halogen good weldability 2.a cream-like mixtrue of solder alloy powder and flux/vehicle

Solder paste(Sn63Pb37)

 

Basic concept and characteristic of Solder paste(Sn63Pb37)

1:Solder paste is a cream-like mixture of solder alloy powder and flux/vehicle system;

 

2:Solder paste should be rheologicle,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 from the mechanical and electical joining;

3:Sorts of Solder paste

 

By solder alloy compsition,Pb-contained or Pb-free solder paste;

By cleaning method,Rosin based,Water soluble,no-clean solder paste;

By flxu type,Rosin,Rosin Medium Activated,Rosin Activated or Organic based solder paste;

By applying method ,solder paste for stencil printing,screen printing ro sysinge dispensing;
