Model Characteristics

1. HIgh efficiency

2. High adhesive

3. Low warpage

4. Perfect poach resistance

5. Lead - free

Formulation Characteristics

1. It is necessary to change the diameter and distribution of aluminium particles in order to increase the density of sintered aluminium film and the electrical properties of the aluminium paste.

2. It is necessary to adjust the ratio of the additives and the glass powder, improve the erosive efficiency in glasses, and increase the effectiveness of aluminium in silicone in doping concentrations.

3. To change the organic phase, improve the distribution of the solid phase in the organic phase and enhance the electrical properties.
