Gentlemen, This is an interesting topic. If one refers to the Nihon Superior patent, they make the following claims. "Germanium makes the crystal finer when the alloy solidifies. Germanium appears on a grain boundary, preventing the crystal from b

A google search on his subject brings several reports on the effect of germanium on LF solder, notably reduction in bridging and icicles, better wetting and reduction on dross production.

Has anyone heard of this? I was told that this would help SN100 in the wave solder by making it flow better at a lower temperature? Thanks James

What a coincidence! Our last solder analysis showed our Ge to be .001% and the lab recommended to bring it up to .005% to get a better wetting. They even supplied a formula to calculate the amount to add based on the % and the quantity of solder in t

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

OH MY GOD!! Finally it's becoming public knowledge here on the streets. YES germanium is in this material. As much as these guys and ALPHA METALS wanted to keep these things secret, anyone with a halfway competent lab would quicky find out why all of

Ha! We do our tin analyis at Alpha and they don't list Ge (that doesnt mean they don't check it). Next time a German Dope head takes a tour in our factory, I'll try to push him in our solderpot and let you know if ze board get ze better wetting.

I totally agree with you on that point, and can only suggest complaining to your supplier about it. I guess I'm fortunate enough to have a supplier that care enough to keep me informed about stuff like that and suggest the proper corrective method. S

Over here in Eurolandia the following Allois are running like a piece of cake. http://www.krepro.no/tinn_pasta_fluss/NiGe-Stangtinn.pdf It is FUJI patent Formula, sold in Eurolandia by FELDER Germany Really a good help in the Lead Free Wave Solder
