Silver paste is the workhorse conductive material of photovoltaics, LED packaging, and semiconductor assembly.
It is also one of the most difficult materials to mix well.

Silver flakes are dense and fine, so they settle; the organic vehicle is light, so it floats; fast stirring traps air; and prolonged air exposure oxidizes the powder.
A poorly mixed batch prints badly, sinters poorly, and measures poorly on resistivity.

Why a Planetary Centrifugal Mixer Fits Conductive Pastes

A planetary centrifugal mixer handles silver paste the way it should be handled — in a closed cup, with force instead of blades:

• Revolution generates centrifugal force that pushes the batch outward and downward, stopping silver flakes from settling;
• Rotation creates shear that breaks up agglomerates and wets the flakes;
• Vacuum (optional) degasses the paste in the same cycle, eliminating voids before printing;
• Sealed cups limit air exposure and protect the silver from oxidation.

The entire process is blade-free.
Nothing touches the paste except the cup, so there is no metal debris and no risk of contamination — important when you are handling high-value, high-purity materials.

From R&D to Production

SMIDA's TMV series covers mixing volumes from 1 g to 100 kg+ (equipment range 150 g to 100 kg+).
Start with the TMV-310TT or TMV-310TTC for R&D, lock in your revolution speed, rotation speed, vacuum level, and time — then reproduce the same recipe on a larger model without re-tuning.
Same platform, same physics, same results.

Quick Answers

Will mixing damage silver flakes?

No.
Blade-free centrifugal mixing is gentle and even, preserving flake morphology and particle size.

Can it mix solder paste?

Yes.
SMIDA mixers are widely used for solder paste homogenization and degassing before printing.
