Solder additive to aid in reducing the solder dross buildup in both static and wave soldering pots containing SN100c. AO1000 can reduce solder usage by as much as 50%. FCT Assembly has developed AO1000 Anti-Oxidant Solder Additive to aid in reducin

Loco: Your post seems to be pasted from a Alpha Metals SACX0807 application sheet. We don't understand the relationship between your SACX0807 and Hoss67 SN100C. They're different alloys.

Indeed Dave, But I can't image the extra .5% silver that alpha adds to sn100c will make a huge impact on the difference between the behaviour of the 2 alloys, especially considering SAC gets exactly the same recommendation.

From alpha metals lead free alloy impurities bulletin: "Levels greater than 0.025% may start to slow the wetting speed and could affect the hole fill performance. If process performance is OK then levels up to 0.05% are OK."

Good afternoon all! Theoretically, there should not be any issues soldering to the SN100C as the tin content of the molten paste alloy should wet to the finish with no problem. I would just ensure that the peak temperature of the joint is above the

We are running a selective solder machine using SN100C alloy. We have had J-STD-001 analysis performed every 2 months and our last analysis showed our nickel content at 0.104%. The max allowed is 0.100%. We changed out the pot (only 30 lbs) but I'

Hello, I produce two types of board. - 100% Thru Hole - 50% thru hole and 50% SMT For the second, I have a bad wetting after the reflow on the top. The pcb board have Au-Ni pad. I use a water soluble paste. I clean the board with a solution with

Hello Steve, Yes, there are differences in the various alloys and I have described briefly below these differences: SN100- a common name for 100% tin that is used to increase the tin content in 63/37. SN100C-Name for Tin/Copper/Nickel/Germanium all

Hello Arnold, Yes, by definition of joint formation, copper will dissolve in lead free solder in order to form the connecting intermetallic layer. There is a distinct difference in the copper dissolution rates of the major alloys being considered wi

Hello Arnold, Just to clarify the Sn100C discussion: Please note that SN100C is the Nihon Superior alloy composed of tin/.7copper/nickel. The key point in regard to SN100C is that Cu does not go directly into solution but first reacts to form an inte
