How to choose a solder paste mixer?

Solder paste mixer equipment is designed for efficient, consistent, and high-performance preparation of solder paste used in SMT production. The mixing process is based on centrifugal force generated by rotational movement. A 45-degree rotational mechanism creates continuous motion inside the container, producing a vortex-like mixing effect that ensures homogeneous blending of the solder paste. Proper mixing is essential to soften the paste, remove air bubbles, and achieve optimal viscosity. Well-prepared solder paste ensures improved wetting properties, uniform distribution, and higher reliability during stencil printing and reflow soldering processes.

How does a solder paste mixer work?

The original solder paste container is placed inside the universal holder, and the operator simply presses the "Start" button. The solder paste mixer automatically blends the material and stops once the preset time has elapsed. After mixing, the solder paste is ready for stencil printing in SMT production lines. The timer is adjusted using speed control buttons, and an LED display indicates the selected mixing time.

SPM-900 solder paste mixer features a dual-rotation system: a rotating arm (~900 rpm) and a rotating container (~450 rpm), ensuring high mixing efficiency and consistent paste preparation. This configuration allows operators to achieve repeatable results and optimise the SMT printing process.

The SPM-900 solder paste mixer is equipped with an electronic timer and LED display for easy operation. The adjustable time range extends from 6 seconds up to approximately 10 minutes, with 6-second increments, providing flexibility for different paste types and production requirements.

The standard container compatibility range is 60–67 mm diameter, supporting 95 g to 500–1000 g containers, suitable for most standard solder paste packaging formats across leading brands. The housing is metal with powder coating for durability. Arm rotation speed: ~900 rpm. Container rotation speed: ~450 rpm.
