Haven't really thought about Philips. My engineers and operators are trained / experienced in Samsung, Universal and Mydata machines. We do not want to reinvest in training at this point. The operator preference seems to be for Samsung, that's why it

You are welcome and thank you for all the inputs. You are right in that these new machines have the camera vision. Like I said in my other post, my engg's like all the machines but prefer Universal and Mydata for a bit more available flexibility like

We do allot of multi layer boards with heavy ground planes or heat sinks attached. We have a Trieber, use RMA flux, solder pot temp at 500F, foam fluxer, spray the top if need be, and would warm up the PWB to around 240F over the preheaters. We have
