Why does this site exist?
Over 25 years ago I became interested in dispensing. I made Surface Mount Adhesive, solder paste, epoxies, fluxes, dam and fill materials and other materials for dispensing. I also sold dispensers and ran the groups that developed, made and serviced them.
Over this time I learned a lot of details and topics that made dispensing work. There is no book, no course on it. It is a topic people "pick up"
This web site has a lot of that type of information. It is not difficult to grasp, just difficult to find, until now
With this web site, you have a collection of information that spells it out, in plain English. Where I have a product with an advantage - I offer it. Where I don't, I try to point you to the place that does.
I hope this site makes dispensing easier and more productive for you. If you have a better way to explain something, tell me. If you want to know something - ask. I hope this will be a growing site and I hope you enjoy it
