| Hello all, | | Our guys here still have some questions on the "optimized" profile which sees a more moderate ramp up straight to reflow temperatures versus the conventional profile which has a plateau at around 150 Celsius. If the optimized profi

Hi Jay, Concerning you PCB, what TG do you expect to use for your lead free process? On my side I have a problem. I order PCB from Canada and from China. My PCB vendor in china is producing a lot of OSP and ENIG PCB, no HASL lead free and in Cana

Good info, thanks for passing along. The company I work for (equipment supplier) ran some tests with lead free material in air and N2 environements for reflow. In the air reflow environement it was noticed that the material does not spread, much li

Hello, I want to ask on suitable temperature profile for PCBs with ENIG final surface finish. I know that it is complex question with many unknowns. When the PCB will be standard 1,5 mm 35/35 Cu and the amount of components will have any influence o

Jay - I read your report and was interested to see that you ran your evaluation on a Heller 1500 5 zone. We have been hearing for some time that a larger machine (7 zone min)with higher temp heaters and fan motors would be required. Is yours a "hi t
