content: linky:http://www.radioshack.com/product/index.jsp?productId=2062711I can't seem to find out if Radio Shack brand solder is multicore. The only reason I'm considering Radio Shack brand is because I know for a fact that it's in-stock nearby and I need it today. Any ideas? Fry's and Radioshack are nearby but close in a few hours... Suggestions are greatly appreciated. Thanks.

content: Haha, I know that's why I'm asking here. The last time I asked someone a question at Radio Shack I had to explain to them what a potentiometer was. Anyone know of any multicore solder that a local store like Radio Shack, Fry's, Home Depot, Menards, etc. sells? I'm in the Chicago, IL area (USA). Thanks.

content: No, it's single-core.Why is it critical that you have multi-core solder?

content: Multicore is a proprietary brand name and is going to be legally protected. If it doesn't have the Multicore logo on the packaging it is not Multicore. That's especially true if it has some other brand on the label.(In case it helps, it is impossible to find Multicore solder in retail shops in the USA. It is very difficult to find it online either.)

content: OK, to be specific Multicore with the Savbit alloy. That only seems to be available in or from the UK.

content: Well, that looks like 50 Tin 49 Lead 1 Cu. Doesn't seem that special to me (I get that the 1% Cu helps).Farnell's US version of the site has it but you pay 20$ per order to get them for you:http://www.newark.com/webapp/wcs/stores/servlet/Search?catalogId=15003&langId=-1&storeId=10194&gs=true&st=savbit

content: Interesting. I didn't know it was approximately 50/50 tin/lead. But whenever I have used it it has worked very well. It has good wetting properties, it flows and fills the joint quickly, and it leaves a nice shiny surface.I think there may be a newer composition of 62 tin, 37 lead, 1 silver. But the information I can turn up is vague on that.

content: If you check the newark link and click on the pictures and zoom them (Ctrl+ scroll wheel in firefox) you can see it says 50/49/1 on the label.Also, you can check the safety data sheet on a product page, for example see this one:http://www.farnell.com/datasheets/369125.pdfDeclaration of ingredients according to EC/1907/2006:Hazardous components CAS-No. EINECS ELINCS content ClassificationTin 7440-31-5 231-141-840 - 50 %Lead 7439-92-1 231-100-440 - 50 %Rosin 8050-09-7 232-475-71 - 5 %Xi - Irritant; R43Copper Metal 7440-50-8 231-159-61 - 5 %

content: That one's for 62/36/2 I think ... if 362 isn't the name of the flux formula. Anyway, this one's with Silver (Ag), not copper. I guess this one is targeted for surface mount stuff, which has silver in the terminals sometimes.

content: I have some Radio Shack solder that is multi core. I just sharpened up a set of ultra flush cutters and was doing test cuts on some .031" solder and could clearly see the multiple flux cores under 10x magnification.
