Solder Paste Mixers

What is a Solder Paste Mixer? 

A solder paste mixing machine is a device used to restore and maintain the essential properties of solder paste during the time of application. A solder paste is usually kept refrigerated to extend its shelf life, given that refrigeration serves to conserve its chemical characteristics with time. However, when the solder paste needs to be used, it cannot be used straight out of the tub. When stored, the viscosity of the solder paste can change as solder particles with a high specific gravity settle at the bottom of the jar. To ensure consistent viscosity, the solder paste needs to be mixed. 

The solder paste is put into the jar and loaded into the solder paste mixer when it is ready for use. The machine rotates the jar within clearly defined parameters in a way that results in deaeration and thorough mixing. These actions lead to a uniform redistribution of the solder particles and the paste returning to its original viscosity; the mixer also breaks up any little air bubbles that may have formed upon storage to minimize solder ball scattering during application. Ensuring a uniform mixture in the solder paste mixer enhances the reliability of solder joints. 

Key specification in Solder paste Mixer 

• Deaeration time: It is the time required for the deaeration of solder paste by the machine. Deaeration is the process of removing air bubbles in the solder paste.  
• Mixing Time: It is the maximum time required by the machine to complete the mixing of solder paste. 
• Mixing Angle: It is the angle of the solder paste jar placed into the machine with respect to the X-axis and is represented in degrees. Usually, the mixing angle is 45 degrees. 
• Revolution Speed: It is the speed of the jar rotating itself with respect to its own axis and is represented in RPM. 
• Rotating Speed: It is the rotating speed of the container in the machine and is represented in RPM. 
• Working Capacity: It represents how much weight the machine can handle.  
• Jar Diameter: It represents the maximum diameter of the jar in which the solder is held.
