20L High-Viscosity Dispersion Planetary Mixer for Solder Paste & Gel

The 20L High-Viscosity Planetary Mixer with Dispersion Function for Solder Paste & Gel is a precision device engineered for mixing and dispersing high-viscosity materials—specifically solder pastes and gels. Below is a detailed overview of its capabilities:

Key Features

20L Production-Scale Capacity:With a 20-liter working volume, the mixer balances compactness with productivity, making it ideal for small to medium-scale production batches in electronic manufacturing, as well as R&D trials.

Planetary Mixing Mechanism:Its planetary motion (agitators rotate on their axes while orbiting the mixing chamber) ensures thorough blending of high-viscosity solder pastes and gels, eliminating dead zones and guaranteeing uniform consistency—critical for electronic assembly applications.

Specialized Dispersion Performance:Equipped with precision dispersion tools (e.g., serrated blades or rotor-stator systems), it efficiently breaks down particle agglomerates in solder pastes (e.g., solder powder clusters) and homogenizes gel formulations, ensuring stable viscosity and particle distribution.

Adjustable Process Control:Offers variable speed settings (typically 100–3,000 RPM) and programmable timing functions, allowing operators to fine-tune mixing intensity and duration based on material properties (e.g., solder paste particle size, gel viscosity).

Electronics-Grade Construction:Built with contamination-resistant materials: 316 stainless steel mixing chambers (to prevent corrosion from flux components in solder paste) and food-grade lubricants (avoiding particle shedding that could compromise electronic components).

Simplified Cleaning & Maintenance:Features detachable agitators and smooth, crevice-free surfaces, enabling thorough cleaning to prevent cross-contamination between batches. Tool-free disassembly reduces downtime for maintenance.


Applications
Primarily used in electronic manufacturing for processing solder pastes (critical for PCB assembly, SMT soldering) and conductive/adhesive gels (e.g., thermal interface gels). It also supports R&D and quality control labs requiring precise, repeatable mixing for material testing.

Usage Notes

Follow manufacturer guidelines for load limits to avoid overworking the motor, especially with high-viscosity materials.

Clean dispersion tools thoroughly after use to remove dried solder paste residue, which can harden and affect performance.

Lubricate moving parts with electronics-compatible lubricants to prevent particle contamination.

Always disconnect power before cleaning or maintenance; use ESD-safe procedures when handling components for electronic applications.

Refer to the user manual for material-specific mixing protocols (e.g., solder paste temperature control).


In summary, this 20L high-viscosity planetary mixer is a specialized tool for electronic manufacturing, combining precise dispersion, contamination control, and process flexibility. Its design addresses the unique demands of solder pastes and gels, making it indispensable for ensuring consistent material quality in electronics production.
