OEM Boy, Reflow depends on your paste type also. Are you using lead free or will you be going to lead free soon? If your are going to you might want to consider developing two different profiles for lead free and leaded pastes. Good Luck! J.D.

does anyone have concrete data on the reliability of lead free components-SN/Bi used with tin lead paste thanks

Hi, What would you consider significantly different about lead-free on flex circuits than tin-lead of flex circuits ? Have you published your experiances that you encountered while changing over to lead-free solder paste from a tin-lead paste ? T

Does alloy 42 lead frame on a QFP100 make lack of coplanarity (let's say 2 mils), a critical factor to have non-wetted leads? Lead coating is tin lead 90/10. afm

Lead melts at 340C and vaporizes at 1740C (at least someone told me that) 63/37 tin/lead melts at 183C, so does anyone know at what temp the lead will vaporize in this alloy or is it the same 1740C?

Hi Dave, Then you think it is ok to use leaded (Sn/Pb) BGA with Lead free solder paste (SAC)and reflow process, As someone told it is not reliable and it should not be allowed to go,

HI, I actually have ask the same question a while back. Yes, using lead free component in a leaded process should be no problem at all. May required just a little hotter peak temp. during reflow, to achive optimal solderability.

Hi all the cost of the nitrogen is lower than the cost of lead free dross, don't forget than the lead free alloy is very expensive. == maintenance be carefull with tools, with a lead bath a key can fall and float, with a lead free bath the key will s
