How to Dispense Solder Paste

From Fishman Corporation
 

 

The Linear Drive System (LDS) dispenser differs from all other types of pumps, in both design and functionality. What this means is that instead of pneumatics, or an auger, the LDS employs a linear actuator that controls the rotation of a lead screw and hence, the linear movement of the piston in the syringe. It is a true positive displacement pump, in that each increment of mechanical actuation - even during ramp up and ramp down - results in a specific volume of solder paste being dispensed, despite the viscosity of the material.

The linear drive system is just that: a system. The dispensing gun, which can be either held in the hand or mounted to a frame, is the working tool, while the control unit is the "brains" that automatically ensures the precise amount of output from the gun each and every time it is triggered.
