Excellent weldability and Strong Adhesion Silver Conductor Thick Film Paste

for 430 Type Stainless Steel

 

Description

LEED-INK DT4306A is an environmentally conductor paste designed for thick film circuit on stainless steel substrate. It is recommended as terminations for resistive heating elements.

This product is non-toxic element and up to European RoHS environmental regulation and has features of excellent weldability, strong adhesion,  good aging resistance, small resistivity and good printing performance.

 

Application

LEED-INK silver based conductor is specially designed for thick film circuit on stainless steel substrate.

It is recommended as terminations for resistive heating elements and acts as welding line and connecting external circuit for the heating element.

Feature Advantage

 

1. Low sheet resistance

The conductor paste DT4306A is with almost pure silver content, and with very low sheet resistance equal to or lower than 2.2mohms/sq by fired thickness of 20μm. It is with stable performance after fired.

2. Excellent printing characteristics

The paste is with proper viscosity, good thixotropy and levelling properties which enables excellent printing properties. After screen printing, the film is well-distributed, compact, clear and smooth.

3. Smooth and fine surface

The fired silver layer appearance is with uniform color and good glossiness. The surface is flatness and smooth, no obvious defects.

4. Strong adhesion

The conductor silver paste DT4306A is with strong adhesion which is equal or greater than 18N on stainless steel substrate and 30N on ceramic substrate.

5. Excellent weldability

The conductor silver paste DT4306A is with excellent weldability. The tin-coat area is more than 95% by method of 235℃+/-5℃, 10s/time with Sn96.5Ag3.0Cu0.5.

6. Excellent solder resistance

The conductor silver paste DT4306A is with good solder resistance that it is equal to or greater than 1 time by method of 235℃+/-5℃, 10s/time with Sn96.5Ag3.0Cu0.5.

7. Environmental friendly, up to RoHS regulation

This insulating dielectric 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.

8. Good Compatibility

The conductor silver paste DT4306A is with good compatibility with resistor paste, dielectric paste and overglaze paste. After fired, there is no bubbles, no obvious yellowing, and with smooth and dense surface.
