Hi AJ, The biggest mistake in the industry today is documentation for lead free assembly required product. We are still seeing prints coming in saying Lead Free / High TG FR4. When in reality standard FR4 170 Tg. material is considered High Tg. and L

Flux is used with both lead and lead free. Lead free usually or always uses a no-clean chemistry while lead uses both no-clean and water soluble dependent upon the application. As far as temp profiling a standard way to go is melting point + 30 C. f

Hi, As far as I know soldering a lead free BGA in a lead process is similar to soldering down some BGA's such as ceramic that had high temp solder balls. Remember back when a lot of BGA's had hi temp solder balls that also did not collapse during re

PB-free Hasl was not mentioned due to the following: 1)Equipment Convertion at the PCB Manufacturing side is expensive. 2)You are subjecting the PCB to Higher Temps than Std. solder. 3)Most PCB Houses are not going to invest in Two Hot Air level

Hi, AJ, In general, the peak PCB temperature is variable depending on the profile used. We try to keep our peak temperatures in line with the paste manufacturers recommended temperatures; ignoring the peak temps for the PCBs. For the peak temps yo

Hi, High temp solder balls don't collapse in current lead based soldering, so lead free balls are similar, and don't collapse, but should still solder ok. They just look different. However I would like to know other peoples experience about reliabil

Hi, What worries me is that a lot of people speak about what they have heard, but there is no firm facts on exactly what the situation is. I did a seminar on lead free a while ago, and was told that going lead free on the components while running l

Good morning gentlemen, I could use some advise as to the min / max windows for the wave process. We have had little problems with our leaded wave but when applying the same process to lead-free wave we are having problems. Obvisouly the temps are

This oven was not designed to support lead free temps. I am sure Manix will tell you the same.

does anyone have experience with reflow of Micro SD cards to PCB@ lead free temps?
