Conclusion
The descriptions provided here are the technologies that form the foundation for all of the most popular dispensers currently used in electronics assembly. However, with a myriad of manufacturers building dispensing pumps and valves, many designs have had subtle additions and enhancements that have created virtual technology "hybrids" of dispensing pump technology. To add even more choices, there are many non-contact devices available such as jet dispensers, spray dispensers and pin-transfer technology. These too, have their place in various applications within the electronics industry.Dispenser manufacturers are always working on better versions of the popular dispenser designs outlined in this paper. And some older contact dispensing technologies are still being used, but, for the most part, they have been replaced because of the capabilities offered by newer dispensing methods. However, some manufacturers may still be looking at ways to resurrect the older technologies in more efficient forms to suit specific applications. That is what is best about any technology. There is always room for innovation whenever there is an application that can benefit from it.
