See, I didn�t bite on you zinc diffusion trick that you tried to pull last week. Understand, in this response, I am NOT trying to bust you. I�m trying to determine what you are looking to understand. [Some times I get so locked into talking a cert

Hello Bachman. SAC305 is the most common lead-free solder alloy, not only for wave soldering but also selective. Most of our selective customers (especially automotive) are using SAC305. What is more important than the alloy to consider is the flux

I, too, have finished qualifying the Amtech paste for a dispensing application. We will be experimenting with the component soldering/stencil printing next. The stuff has proven to provide the best of both the no-clean/low solids and water washable

Several points are: * There�s quite a bit of background on IMC in the fine SMTnet Archives. I�ll try not to duplicate it. * If you have a smooth and well-formed solder connection using fairly common materials, you assuredly will have IMC. Any evide

Murad: Your customer is smart to be concerned about the affect of changing production processes on product reliability. Your Company is smart to inform customers and keep them in the loop about these changes. In developing your demonstration of th

As an addendum to Daves posting, please consider that: There is no such thing as no residue fluxing. A no-clean must herefore, have benign residues - in other words, they are not as efficient at removing surface oxides to enable good solder joints. S

Here are some answers to my questions after a good research. I also added more definitions that could help understand this esoteric language used in assembly, specially surrounding fluxes and their use. In blue italics are comments and extracts from
