We are an OEM manufacturer, and are beginning to look at how we will be affected by the ROHS and WEEE directives. As of now we have many questions, and few answers. Does anyone know of a good comprehensive source where one could get information on:

Hi, I am an Engineering student doing some research on the component/nozzle interface on SMT Pick and Place machines. Could anyone tell me the force at which the nozzle hits the component as it is picked from the feeder or the placement force on a

Has there been a definite date for the total move over to lead free? Will it be 2004 or 2008. Also is there a direct replacement for leaded solder, I have read various articles on numerous alloys suggested for the switch, such as bismuth, tin, copper

You're correct, for every dumpster full of paper written about solder, there's a sentance written about fluxes. There's dribs and drabs about fluxes in most of the soldering books [ie, Manko, Klein-Wassink, Judd, Strauss, etc] and most of that is ve

Thank you for helping finding a direction for my answer. I found interesting things on fluxes at this site: http://www.smtinfo.net/docs/Electronic%20Production/25.htm Due to the lack of precise and concise information on the subject, I think I will w

Yes, I can see your problem, the nozzle makes only good contact in the center and so the ends don't make good contact. The ends tend to curl up during reflow. There were two suggestions to solve this. 1) Let the operator push down the labels befor
