Hi,

Make sure you use right solder paste for your choice, e.g. with Ag for greater weeting finish.

Dave,
I totally agree with your choice and the reason for it.  It certainly has worked for us for 12 years.  Although we don't have our products hung on a cell tower in space, we certainly have our products hung on cell towers and building around the world in all kinds of environmental conditions.

Regards,
George

Hi Steve - my vote would be the ImAg and lead-free assembly choice. All 
three of your options should work with each having both pluses and 
minuses. My preference is to solder to copper rather than nickel if given 
a choice.

[TN] Leaded or non






Hi All,
I have an 18 layer rigid flex (buried and blind)  that we are preparing to 
put the surface finish on and then assemble.
Lots of BGA's etc.
The BGA's are lead free.
Options:

1)      ENIG and lead free assembly

2)      Immersion silver and lead free assembly

3)      HASL and leaded assembly
Hi end military product.

Thoughts or comments would be appreciated.
Thanks. Steve Kelly
