Feature Advantage
1. High Electronic Conductivity
The low temperature curing silver paste is with high electrical conductivity, and the volume resistance could be controlled under 2.4×10-4Ω·cm.
2. Good adhesion
The tantalum capacitor using silver paste DT1203 is with good adhesion. Stick the printing surface with 3M tape and then quickly vertically pulled off, no Ag transfer.
3. Excellent Solder Resistance
The silver paste DT1203 exhibits excellent solder resistance, and the dip soldering area is up to 90%.
4. Good printing properties
The paste is with proper viscosity, good thixotropy and levelling properties which enables excellent printing properties. After screen printing, the film is well-distributed, fine and smooth.
5. Environmental friendly, up to RoHS regulation
The low temperature silver paste contains no toxic materials and heavy metal ions such as lead, Cadmium, nickel, and it is environmental friendly and meet environmental standard of RoHS regulation
