Air-powered dispensing systems use controlled pulses of air pressure to dispense solder paste from syringe reservoirs in uniform amounts. Air-powered dispensing equipment comes in many shapes and sizes. Each and every unit has at least two characteristics in common with all the rest: air pressure regulation and dispense cycle control. Compared to the use of wire solder and solder preforms, dispensing solder paste with air pressure is a relatively simple and much more flexible option. One would think that with only two machine variables needed to control dispensing, air-powered application of solder paste would be foolproof, but this is not the case. Each section of this paper addresses a process variable and provides an explanation of successful and unsuccessful implementation for each.
