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

| Has anyone had any experience with using this alternative plating process? Some board houses are pushing toward this plating. Is there any long term data on this process? Any problems experienced with smt and thru-hole? I've heard tin whiskers to b

Great, just what we need - Psuedo science. To paraphrase: We tried 99.5Sn/0.5Cu & it didn't work so we couldn't be bothered to try any other lead free alloy. So give us an exemption else we'll bury you up to the neck in the stuff. I have no probl

Hi Patrick, Sorry, wrote it in a hurry on Friday afternoon, I meant show us evidence of a scientific trial on all or at least some other alloys. I accept Tin whiskers and other similar phenomina exist, I even accept that the whole ROHS directive

Slain, A melting point of 300C would be a little too high for the components and tinny boards. I just heard they will market the watches as Swiss "army" watches which makes them exempt.

Rob, it's not psuedo science, it's business. They have a problem, and have evidently tried a solution based on applying for an exemption. It's probably cheaper than trying every other possibility. I think it's the EU with the psuedo science to back

Hi Pat, It's all going to be OK - they're giving us something else to occupy our minds: http://www.electronicsweekly.com/Articles/Article.aspx?liArticleID=38641

Rob, Thanks for reminding me why I left Europe and moved to the US. I admit taxes were part of the reason too. Cheers

Strangely enough I'm in the process of getting measured up for my Crocodile Dundee hat.
