So just to clarify.... If i bought a KIC 2000 I could run that one unit over both my waves and through both my ovens (leaded and lead-free)? Or would I need additional equipment to use it on the wave?

Just like to know what you guys thoughts regarding mixed alloys. Production run SAC305 and some components are SAC105. So, which profile should you follow. SAC105? or SAC305.

Why not follow SAC305? you would do so for any other component finish wouldn't you? A component finish of pure Sn would also not call for a pure Sn profile, would it?

Has anyone heard whether the elevation of a plant can effect solder joint formation? One plant at sea level, one at 7,000 feet elevation... same equipment and profiles, big voiding defects at higher elevation. I did a search and found no similar post

On an assembly reflowed in air saw the same thing: 0201's with a grainular solder joint, but 0402's and above with perfectly formed joints. Reflow profile all within acceptable tolerances. Reflowing in nitrogen solves this problem, but increases t

Hi, I wondering if someone know the anwser to that. I'm using a solder paste 63/37 and on the solder joint we have a tiny little layer or flux who is like crystalin. I try to play with my profile the get it off but I don't get much success. So D

I guess I took too much time editing my response. :P The bottom line is that unless you're measurements are at least as repeatable and accurate as your machine's closed loop systems, it's a waste of paper *BUT* makes nice wall art for tours. I like
