On understencil cleaning: * It's a good idea to do this to reduce printing defects, as you say. * We clean dry. * Our cleaning frequency varies acording to product, maybe ranging from 10 to 20 prints, averaging around 12 to 15. * As long as cleaning

Sorry fellas -disagree. We only clean our stencils in the ultrasonic machine at the end of the run. If the same pcb is up the next day we clean them by hand. We use Electrolube SSS and the used rolls from the in line under stencil cleaner. Wipe the

Your concern should be do you have a glue process that can keep up with the FCP6. We ran a GL541 in line with a CP643 which the glue machine was actually a bottle neck because if you run SOIC's which require more glue dots then it will slowdown the

My input are: i. To solve tape not pulling back if it is due to high per is better to use more feeders to minimize this issue. ii. To slow down printing speed. Hence, has proper line balancing which minimize board idling before pick and place process

See Fiske first line. I'd bet You are bending or catching the assembly in the ICT. How many probes at 8OZ each? do you use on that ICT? 800 probes = 400lbs. See "Flexure induced failure of BGA solder joints" by Compaq Houston TX

Hi Chris, Mini stencils are a pain to line up and then holding it still while trying to print is almost impossible. We used to use tacky flux but found the Stencil Quik gizzmo from Best works the best. Give it a try. http://www.solder.net/stencil
