Hi everyone We plan to use on our smt line sac 305 and on our wave soldering sn100c. Will there be a compatibility problem if we do make touch up with sn100c on smt or touch up thru hole components with sac 305 ??? Thanks for taking time to reply

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

If you do SMT with an SAC alloy, and the Wave Solder with SN100C, what is the impact of accidentally reworking the through hole parts with an SAC alloy wire solder? Or reworking the SAC alloy with an SN100C wire solder? Brian

Yes, there have been many issues with the fast dissolution of copper by the SAC305 alloy. In fact, there are companies who have disqualified it for repair operations due to loss/thinning of the pads. SN100C dissolves copper much slower than SAC305 an

Does anyone know what are the available type for LF solder balls? I only know LF35. Is there any other types besides this? Does anyone have the data for the hardness of SAC type and LF type solder ball? Many thanks in advance

I will try with temperature 255 C degrees. The wetting force vs. solder temperature for SAC305 is more than 265 C degrees (the temperature of trials). Thanks for the advise. Regards

Hi Jason, Did the SAC paste wet other board finishes adequately? I have seen no issues to date with solderability of SN100CL HASL boards with our No Clean pastes. Regards, Bob

I've tested boards with SN100C HAL finish, and wetting to the PCB finish was poor at best, using a no clean SAC305 paste.

CEMCO Uk have done testing using SACX0307, SAC305 and Sn/Cu/Ni. The copper dissolution tests (report available) conducted at CEMCO showed that the lowest copper erosion rate was achieved by SACX0307. Regards Gerry

Any issues in your experience using SAC305 for reflow and SN100C for wave on ENIG pcbs? I've seen the CD, but there's not much specific data regarding ENIG pcbs Thanks
