Studies showed that there are no issues mixing SN100C and SAC305, I believe that AIM has this info. Russ

Is there anybody out there doing this scenario: SAC 305 Reflow & SN100C Wave and Selective Can the 2 alloys be mixed on 1 board, say, SAC 305 for SMT, and SN100C for thru-hole? Are 2 different rework chemistries needed, or can one use SN100c wire

I had a vendor change thier lead finish from tin/lead to a SAC305. We built up several assemblies before we realized the change. The reflow process is a standard leaded profile peaking at 220 C. What are the reliablity concerns with mixing the tin/l

Sheldon, Try using SN100C wire solder. It seems to extend the life of the tips plus solder joints look much better. We use both, clean and No-clean. We had the same problem while using SAC305... Thanks, George

I tried some SN100C from AIM... On only one array. It flowed well on the chips but did not like the finish on the SOT23's on the board. I did not have enough arrays to mess around, so we switched it over to SAC305 and had no issues. I'm guessing w

Hi Steve, Although your opinion is valid, calling something from a respected Japanese manufacturer crap is a little harsh. I have seen many people solder very well with all sorts of leadfree alloys - not producing crap. I've already had a play wit

If you can change to SN100C do it. The nickel prevents the high tin content from eating away at the metals on the tips. Similar to what the Lead did in 63/37 alloys. This Koki crap is just that, crap. 99% tin??? Thats what is causing the problem peop

Dont't bother to answer real idiots! I can relate to a similar problem. We also use SN100C alloy and the solder pot get(got?) contaminated with the alloys from the SAC305! How can this be? Strange thing happens during the soldering process, and it o

Just wondering what the companies that are use SN100C are using for reflow (I guess SAC), and especially for handsoldering. Do SAC and SN100C mix? are there any studies proving this?

We have used the SN100C for over a year now with fanastic results. We use the SAC305 for SMT and SN100C wire exclusively. There are no problem mixing the alloys. I am also on the commitee for the NASA testing. The SN100C did out perform SAC and SnPb
