I'd like to get more information about pick and place nozzles. How can I learn more? ... What do the nozzles look like? Are there different shapes? Are custom nozzles sometimes used for custom parts or are the nozzles mostly standardized? What kind

Let's be more specific. Why do you need to clean the boards? I assume it is for testing purposes, probe contact concerns and the like. This is the only economical reason I can think of to clean no-clean flux residue from your assemblies. Before y

Thanks dyoungquist and tech 1, Things have been crazy lately installing Mylabel and keeping up with customer demand. I have been looking into buying more reels for the high runners (caps, resistors, IC’s that we use a lot) and I think we have a shot
