IPC-7351 is the most complete I have found but is still missing some. Look here http://www.ipc.org/contentpage.asp?Pageid=4.6 Jerry

Hi Ken What exactly the best reffered angle for Sn/Pb & Pb-free soldering? Is there a site where I can read the basic engineering concepts about this topic?

About the anlge typically is 5-7 depending on the machine. If solder smt components, the best is to use (swich on) double wave machine - (swich on both) chip and laminar wave. Regards.

Hi, I`m thinking what would be the best way to avoid icicles on lead free solder!

Hi, What would be the standard band width for Pb-free soldering? As per my knowledge this should be 3cm to 6cm. What is best?

thanks for info Most of the defect soldering joint do not take place. Observe that PCB not cleaned properly & also component wetting not good. testing staff expect that all card what ever they receiev shuld be 100% ok. they straight forward complain

What is "Black pad"in ENIG(Electroless nickel/immersion gold), how to solve if it happen in SMD BGA solder joint?

Thanks very much! In fact, "Black PAD" phenomenon have been found in our product, the total BGA came off PCB during drop test. if we apply the underfill to BGA after SMD process, Could the underfill add reliablility of product?

Are the leads actually pulling off the pads or are the pads coming up as well? Did you ever try this "experiment" before you used lead-free?
