* Try 1.5C / sec from RT to 165C * Hot soak at 165-175C for up to 2 minutes (I'd start with 60 seconds flat soak.) * 60-90 seconds TAL (I's start with 60) * 230-240C Peak. Thanks, Mario

Not sure why you'd want to immerse an assembled board in 60-70*C IPA for an hour, but I doubt there is much published material on the topic * IPA is toxic * IPA is flammable at room temperature and heating IPA to 60-70*C only makes it more so * There

We have CP60 in the last 2 years, and CP63 1 year. You should check your local C/S about spare part stock, service support, and training for your employees. My conclusion about Samsung Techwin MC's is: cheap, and working well. But dont except too muc
