Introduction
The solder paste mixer is an essential device in SMT production, designed to automatically mix solder paste to restore uniformity between the alloy powder and flux. The SR-500 model, produced by THINKY, is a professional-grade mixer widely used in production and research environments.
Product Overview
The SR-500 is an atmospheric pressure, single-cup, dispersion and mixing system with deaeration capability. It uses a rotation and revolution propeller-free mixing system that uniformly mixes solder paste without introducing air bubbles or causing overheating.
Key Features
1. Direct Container Compatibility
The SR-500 can directly accept commercially available 500g solder paste containers without transferring contents. This reduces contamination risk and saves preparation time.
2. Cold-Start Capability
Solder paste can be taken directly from the refrigerator and adjusted to optimal temperature and viscosity in a short time without waiting for it to return to room temperature. This significantly improves production efficiency in fast-paced environments.
3. Bubble and Deaeration Removal
The machine removes air bubbles from solder paste, which are a common cause of soldering defects such as voids and solder beads. The deaeration function ensures the paste is in optimal condition for printing.
4. Rotational Balance Adjustment
The SR-500 includes a mechanism that allows partially used solder paste containers to be set and balanced properly, enabling consistent mixing even when the container is not completely full.
5. Optimized Mixing Recipes
Step-by-step mixing formula settings allow easy adjustment of solder paste viscosity and temperature. Operators can customize mixing parameters based on paste type and ambient conditions.
6. Syringe Filling Integration
The conditioned solder paste can be loaded into syringes using the optional ARC-40H syringe filling machine, enabling precise manual dispensing applications.
7. Syringe Degassing
With an optional adapter, syringe-packaged solder paste can also be deaerated, making the SR-500 a versatile solution for both bulk and syringe packaging formats.

Operating Precautions
- Always unlock the transport locks before operating the machine
- Ensure the container is symmetrically placed and securely fastened
- Do not overfill containers to avoid splashing during mixing
- Allow the paste to rest briefly after mixing to let bubbles escape
- Clean the container adapter and O-rings regularly to prevent cured paste buildup
