Hi Jerry, Thanks for the info - it's very helpful. I'm assuming (as it carefully refrains from saying it anywhere!) that SAXC0307 is Sn99/Cu0.7/Ag0.3. Cheers, Rob.

With twenty five machines working with the LFB227/S on our little island it does seem to work well. Wetting is good compared to Tin/Copper and flow is comparable to 63/37. Biggest problem sticking 3 - 4 % Ag in a solder ignoring the patents and royal

a french subcontractor had tried this alloy for a show (in france). I was here , the PCB was not to hard to weld , but the results were not as good than Sn63pb37.(of course) the advantage is the price. see cookson for details.....

Hi does anyone have any experience of running Sn 99 Cu0.7 Ag 0.3 solder in their waves? Also is there any reliabilty data available? I think it may also be called C7A3. All I can find is a brief mention in a table in IEC 61190-1-3 2004, and on a pr

Here are some general rules for lead free wave solder: Noble aloys will cost more. Period. The cheapest metal on earth is lead. Costs can only go up in Lead Free. Consumer grade and class 2 electronics will most likely use Tin / Copper for wave.

Oh silver and its...improved solderability over tin / copper. BS if you ask me. Look to your flux and thermal profile for wetting spread. Ask yourself just how much "wetting spread" do you need to fill a barrel? I have the same 100% barrel fill

I have got information that MicroFlex (re-engineered version Ultraprint) screen printer from MPM can handle with 0.3mm fine pitch. Does any one make 0.3 mm print test?. What is the effectivnes MicroFlex for 0.3 fine pitch and is it reliability proces
