The optimal profile to choose is determined by the following factors, (1) thermal mass and distribution across the board, (2) reflow temperature range needed for a particular alloy, (3) the nature of flux. When the thermal mass is small, such as cell

Use the thermal recipe suggested by YOUR paste supplier, as the starting point.

Hi Tom, Thanks for the compliment. I've been researching and planning for the time that my company would go lead free since late in 1999. I hear you there, how do we know that the component is lead free. Baring a leap of faith with your vendors, I

| 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

First and fore most is to find your paste manufacturer spec sheets. Read it over several times and let it all sink in. Then call them with questions as they want to keep your business so their engineers want to help you use their product. I assume y

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

How would you like to have this guy evaluate your reflow profile? It was in response to an auditor who require someone they had monitor temperature in both Fahrenheit and Celcius. What a geek Don't put him on the spot. That is not a good thing to
