Low Volume Resistivity Good Adhesion Low Temperature Silver Paste
for Tantalum Capacitors
LEED-INK silver conductive paste DT1203 is a general purpose
coating suitable for direct application to most substrates
including plastics and it is special suitable for tantalum
capacitors applications. It is non-toxic element up to European
RoHS environmental regulation (2002/95/EC).
It has features of low volume resistivity, good adhesion, excellent
solder resistance, high electrically conductivity, etc.
The low temperature curing conductive silver paste refers to the
silver paste with curing temperature of 100-200℃. The silver paste
DT1203 is mainly developed for capacitors including tantalum
electrolytic capacitors and aluminum electrolytic capacitors.
It is designed to exhibit good adhesion and excellent solder

from Date of Shipment
1. High Electronic Conductivity
The low temperature curing silver paste is with high electrical
conductivity, and the volume resistance could be controlled under
2. Excellent Solder Resistance
The silver paste DT1203 exhibits excellent solder resistance, and
the dip soldering area is up to 90%.
3. 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.
4. Good Hardness
Test the hardness of a standard line with a pencil hardness tester,
the hardness of silver paste DT1203 is equal to or greater than 2H.
It presents good hardness property of the silver paste.
5. 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.
6. 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
7. Low Consumption
the low temperature silver paste DT1203 is specially developed for
low temperature curing applications. By years of improvement, we
are keeping develop and reduced the noble metal content to reduce
the cost and provide most cost efficient materials to the market.
