Try: Tungsten, tungsten carbide, ceramics like boron-nitride or how about pyrex glass? Glass blowers could make "hooks" that connect to a cross bar. I would NOT use aluminum (even if anodized). Try stainless steel 316. 303, 304 do not have enough

Hi, What's the best process for going lead free? Ordering lead free parts and using them with current paste, and then once all the parts are lead free, moving to lead free paste as well? Then the wave will be fun to change over. What a nightmare th

You can purchase pad repair kits at some "radio shack" type stores or you can order them from some such as Circuit repair corp. If you know where the signal traces go from the individual connector pins I woul;d recommend just adding a wire frm the p

Good afternoon, You have to use lead paste since none-RoHS components won�t withstand elevated temperatures. Solder paste manufacturers offer a lot of transitional pastes designed specially for mixed process. Ask your paste supplier for transitional

Today is more complicate to find components with lead than with "lead free", and the, I think that you have very feww lead components. And, if don�t work on exceptionals companies, you MUST use LEAD FREE PASTE. In one case, or in the opposite, the re

We are using lead paste on both sides, the only reason we need to change the profile is because the BGA is lead free. I decided to run the BGA side first, then the connector side. This way I am not running both sides through on a hotter profile.

Are you using lead free paste also? Are all the other parts on side 1 ROHOS ? etc.. can they handle your leadfree profile. Those need answered 1st. But to answer your question. Yes you can run the BGA side 1st ( hopefully with leadfree paste and ho

everything else EXACTLY the same? meaning exact same product number from the same manufacturer same fluxes used in the paste? no additional no clean "touchup" or hand soldering operations? No expert by any means but it would seem odd to me that the

Most white papers, like this one http://members.ipc.org/ipclogin/ipcmembers/IPC/Route/0706/0706techpaper.pdf, have written that lead contamination in a lead-free solder joint leads to all sorts of reliability problems. Consensus is that, if the cont
