NoFlex Linear Drive Technology Ensures Accuracy in Dispensing of Adhesives and Solder Paste

From Fishman Corporation
 

 

In dispensing adhesives and solder paste for electronics assembly, all types of dispensers have traditionally relied on pneumatics to "push" the material out of the barrel reservoir. Unfortunately, problems inherent with this type of dispensing, such as inconsistent dots due to variations in air pressure, changes in viscosity due to build-up, and, in the case of solder paste, separation of the paste and flux due to pneumatic exertions. As a result, technicians have been required to live with the uncertainties and shortcomings of pneumatics and essentially conform the process to the capabilities of the equipment. Production delays due to the need to calculate and recalculate settings, material waste, inconsistent performance, and rejected parts have become expected and inherent factors in the process.
