Electronics Applications Understanding the technology behind popular non - contact dispensers for electronics assembly. There are four basic dispensing technologies being used today in Electronics Assembly. This article will try to match the basic dispensing technologies to the types of material they are best suited to dispense.
Most manufacturers have special models of dispensers available for use with abrasive materials.
Because these materials do not affect the basic dispensing technology but are more dependent on materials used to construct the pump or valve, the various types of abrasive materials are not included in this comparison. Applications Within the basic technologies, there are many versions of specific pumps and valves that are available. A dispenser must be compatible with the material and be efficient in delivering the deposition configuration required. By comparing the basic design and theory of operation of each technology to the specifications available on all manufacturers' product sheets, it becomes a simple task to see which design is appropriate for any specific use. This will help select the correct product for the application.
