A solder paste mixer is a machine used in surface-mount technology (SMT) to prepare solder paste for printing on printed circuit boards (PCBs). It automatically mixes and tempers the paste inside its sealed container, ensuring a uniform consistency and proper viscosity before the paste is applied to the board. 

Solder paste mixer works

Solder paste is a thick mixture of powdered metal alloy and flux. To achieve a high-quality solder joint, the paste must have a uniform consistency and be at the correct temperature. Solder paste mixers typically use a centrifugal or pseudo-planetary motion to achieve this without incorporating air bubbles into the mixture. 

Key benefits 

Using a dedicated solder paste mixer provides several advantages for SMT manufacturing:

• High reproducibility: Manual mixing can be inconsistent. An automated mixer ensures that every batch is prepared to the same standard, improving quality control.
  
• Reduced defects: Proper mixing improves the paste's printability, wettability, and reflow performance. This significantly reduces soldering defects and increases overall assembly yield.
  
• Faster production: A mixer can ready refrigerated solder paste for use in minutes, which is much faster and more efficient than manual tempering and stirring.
  
• Prevents contamination: Keeping the solder paste sealed in its container during mixing eliminates the risk of introducing moisture or contaminants from the air.
  
• Increased safety: Automated machines include safety locks and emergency stop features that prevent the user from accessing the moving parts during operation.
