There a number of studies like this published by component fabricators. Many can be found on the net. For instance: http://www.amd.com/us-en/assets/content_type/DownloadableAssets/Pb-free_Board-level_reliability_study.pdf

Could you direct me to a Standard or Study that has used this termination with 67/37 tin/lead solder please? I am looking for the recommended reflow temperature requirements and reliability issues for the completed product. We are receiving this type

Kester offers Tin-Copper AND Tin-Copper-Nickel. The Kester K100 alloy is a Tin-Copper-Nickel material that is very similar to SN100C. Straight Tin-Copper isn't tremendously popular but can be used in low-cost, consumer-electronics applications wher

Look at: http://thor.inemi.org/webdownload/newsroom/Presentations/09.pdf Page 47 shows both alloys to be similar in reliability although its a little troublesome that the particular defects are not isolated as I feel there is a big difference betwee

Hello Greg, I agree with you that the article in SMT Magazine should be studied very carefully as it contains many errors in respect to SN100C. The testing performed was a DOE and was not an optimized run. There is also a statement on dross generatio

What you are most likely dealing with: Insufficient Pure Sn layer ( multiple causes ) Because elevated temperatures accelerate the diffusion process, the thickness of the Pure Sn layer will reduce during every thermal cycle... ( bakeing PCBs, S

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

Are the components 100% tin plated? Thats what we are buying and we have no problem at all soldering with the same profiles we always have used and we use the same alloy as you but different mfg. We have not had problems soldering tin plated parts wi

I spoke with a Tech at Superior Flux. He confirmed that Superior 515 will absoluteley turn yellow at room temp. Hydrobromic Acid in the flux, as it binds the hydrogen gases off and the bromine turns yellow. What is weird, is that Tin Bromide is y

But Vlad was talking tin and Davef gave intermetalic thicknesses which Vlad said needs to be avoided by having a few microns of tin. I'm not 100% sure but I suspect that DaveF is not convinced that Vlad knows what "intermetalic" means.
