I just hope that lead-free alloys will only be used in tropical climates and above 13 C. Check here: http://materials.open.ac.uk/srg/srg_tp.htm Patrick

Interesting document. They are using a very high tin content alloy 99.5%SN, and suggest they can cange to a 90/10 PbSn alloy that will still mean they meet the RoHS Directive as alloys over 85% lead are exempt within RoHS. so if they used this they c

Kester is offering a tin/copper alloy for lead free. Any comments regarding using just tin/copper as opposed to tin/silver/copper or tin/nickel/copper? the price is low but why wouldn't everyone else offer just this alloy as opposed to the standard S

You can use straight forward Tin/Copper but it flows very poorly so solderability is an issue. Dosing with Phos improves this but need to stay on top of it. We have supplied some 3.8%Ag alloys for flow they work well but you get a small 'chill point'

It could be that the Sn96 has dissolved the Tin rapidly and gone for the Copper. What dwell times are they using with the irons? Probably better off using a Tin Copper alloy for reduced dissolution worth a try Cheers Greg

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

Hi all, I just wave soldered 40 boards (20 if Imm Sn and 20 of Imm Ag) using SAC 305 (in this case the wave machine manufacturer (electrovert) suggested the alloy too). plan to carry out x-sectioning to see the results. overall, just from the visual

We use SN100C for wave soldering and hand Lead free soldering and have had very good results. The wire cored solder for hand soldering flows good and makes very good solder joints. The SN100C in the wave solder machine also works very good. We use
