Thank you.

You are right, I forgot to mention, that I'm refering to Lead components, not RHOS compliant.

It is right that reflow Temperature are between 200-235{ most of companies, including Altera recommend on max temp. of 220 C} but since I deal with quite large BGA's , and there is a difference in temperature between it's parts, specialy between case and balls temp. , I want to know what temperature the balls must feel for good melting.

Thank you!
