Hi Dave, 1. As far as speed of removing componants, we use a board preheater to bring board temp to about 150 C. Then add a flux and then flood all 4 sides of the componant with the low temp solder. Using a suction tool the part comes right off. The

Russ has a hint by saying "too long of a soak at too high of a temp or being in reflow for too long/hot". I think the board should stay in the oven for 3-4 minutes, spending 60-90 seconds of which during reflow. in order to stay in the oven for 3 m

I have been reading the forum to try and figure out what brands to look at for Pick and Place machines. We need around 3,600 cph, and would like to be able to handle 0402, soic, tssop, and perhaps as little as 0.020" pitch. Max pcb is 9 x 13". Looks

CP6/7 feeders are mechanical indexing machines, and the springs, cams etc wear over time leading to misfeeds & increased attrition. You can just strip & repair but especially on the 8x2 feeders the pick up position is critical. John, I'd check with

The 22,000 cph is for the dual beam machine (C5d), which is in production now alongside our single beam machine. They are built on the same frame and share many assemblies. In fact we only show rendered images of both machines. This is to show the
