You will also find an increase in the costs of the paste

Wettability also will increase, so it could generate briges on fine pitch leaded component. Gabe

I'm looking at an application that would require 62/36/2 solder paste. We currently run 63/37. I'd like to change across the board to prevent a mix up, but I don't know what concerns/issues that might create. The PCB's we currently run are HASL fi

I have only used this on Mov assy's, never on boards. If using no-clean does the joint appearance enhance AOI effectivnes? Anyone tried it? The cost would be worth it.

Russ, you are right, I've seen briging on 16 mils pitch on OSP (ref under N2),to avoid it needs more care in paste volume. Easier was by 63/37 (Clean) and N2 (on OSP double sided PBA). Regards Gabe

It is a direct switch over from what I have experienced. You don't need to change anything. You should expect to see a shinier/brighter joint. We actually consider them totally interchangeable with no worries about running either on any product.

Gabe, Interesting, I have never encountered that before. Why would you think we have never seen it? I would think that the increase in wetting would help "pull" the solder onto the leads reducing bridging. Am I wrong? Russ (not a rocket scientis

Can also reduce leaching of certain types of components. Also, dont expect to see a "shiny/bright" joint if running Nitrogen in the relfow unit, you'll see a dull/smokey like joint...if running Air then sure,let SHINE! my 2Cents DaveK
