|Paste:||Lead Free Solder Paste For Screen Stencil Printing||Place Of Origin::||Guangdong, China (Mainland)|
|Application::||Most Of The Case Of Soldering Opration||Ingredient::||Tin Silver Copperand Flux|
|Name:||Silver Solder Paste|
silver solder paste,
no clean solder paste
Sn99Ag0.3Cu0.7: 500g per box;100g/pc,10kg per carton; melting point:227deg
Paste designed for soldering SMD components in production processes that do not include washing phase.
It is based on a ‘no clean’ flux type, that does not require cleaning and its residues do not cause corrosion centres .
The product cooperates with all the lead free alloys, it exhibits good tackiness and wettability of soldered surface.
It does not lose its physical and chemical properties even after being left for 20 hours on the PCB. This time depends on conditions in room: humidity and temperature.
