I have a steckfuss pinpointer 18 you can buy in Toronto, loaded with lead free alloy. peter08 at broy dot com It is not mine, but belongs to a broker and is in my building, will be inexpensive.

Look at this article http://circuitsassembly.com/blog/?p=191 The EU commission totally lost contact with the real world.

Here's a good thread on lead free reflow recipes http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=47575

Quick production (no "pasty" phase) > High joint surface quality > Good flux action > No discolored, corrosive, or substantive residue of any kind > Lead-free is not a concern ;o) Any input/ideas are appreciated. Thanks!

Dave is correct. You are running out of flux due to such a small solder deposit. Try shortening your overall time in the oven. Less than 4 minutes to peak is where I'd start.

Anyone experience high voiding levels in SMT lead free solder joints when the CHIP has bright tin plated end caps ? In the same process, Matte tin plated CHIPs don't show any voiding issues.

Inds, This will happen with all lead-free alloys having a tin content above 70%. It takes about 30 sec. for a molten lead-free alloy to totally dissolve a copper pad. The higher the temperature the shorter the time and visa versa. The scary part of

Dear all, As far as I know hot tear or shrink hole defect only happen at plated though hole soldering, especially for those lead free wave process. Recently, a laboratory engineer had done cross section on some of the SMT BGA ball and IC lead solde

Hi "theSaint", We are using SN100C in our wave solder machine. As far as the solder itself, the wave process follows pretty much the same concept as leaded solder. You bring the assembly temp to 90 C or more before the actual wave. Sometimes for mul

Also, have you considered the possibility that if you solder on an existing joint on a board that was built with SnPb solder, even though you are using leadfree solder wire, you would now contaminate the tip of your soldering iron. If you then start
