Not sure about Sn/Cu/Ni large market share here in Europe as we have a large part of the UK market with SACP0307 alloy 0.3%Ag introduced over Two years ago Also worked against Sn/Cu/Ni alloy with large TV Co and they went with 0.3%Ag due to reliabili

What aload of rubbish - prove it, we have over 320 users in the UK alone using the SACP0307 solder with great results, and the biggest advantage they have is they can multiple source the solder not stuck to one company who has purchased the patent an

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

Hello Greg, Glad to hear your success with the SACX0307 copy. By the way, does the P mean it contains phosphorus? Does yours also contain bismuth like the SACX0307 (according to their plumbing solder patent for X0307)? In response to your discussion

Many trials conducted so far from single sided to Mixed technology dual wave with our LFB227/S 0.3Ag silver Lead free. Results are excellent, some say better than 63/37. One continueing problem though is the age old area of undercured resist and runn

Dear Eric, in my opinion this is a very complex problem, that require to know many details for answer. For example : 1) what about the PCB finishing ? Have you verify the quality of they ? 2) what about the solder paste (the exactly composition)? 3)

Sorry Bob Could not respond been away busy. Just to correct you, we did not copy the SACX as we brought ours to market at least six months before so how could we copy, it is also a little different, but nicely reassuring when the 'big boys' do some

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'
