Jacki, Lead-free Cu based alloys with melting point below 210C don’t exist.

Question about leaded parts used in leadfree soldering process

Electronics Forum | Fri Apr 07 11:19:55 EDT 2006 | muse95

Technically speaking, most likely yes it will work, unless possibly it is a BGA. There are issues surrounding BGA's. Here are some of the general issues: On any type of component, if the Pbfree solder you are using contains bismuth, then the Pb in

Hi All, Anyone having problems with Peelable Mask during Leadfree Process? as in Melting Dave...

Why not use lead-free plumbing solders in electrical applications?

Electronics Forum | Tue Apr 27 15:43:41 EDT 1999 | Joseph Holmes

Another basic soldering question. I notice that lead-free solders have become required for plumbing applications due to legislation. In a local hardware store, I noticed the existence of lead-free solders (based upon tin-copper I think) with a melt

Solder Paste Flux corrosive?

Electronics Forum | Fri Sep 25 12:26:34 EDT 2009 | clampron

Some information on the web regarding RoHS and tip life... What problems are there for using Lead-free solder? ? Higher melting point of Lead-free solder may cause physical and thermal damage to components and PCB. ? Lead-free solder has poor

PB-Free HASL and Leaded Solder

Electronics Forum | Thu May 13 20:40:25 EDT 2021 | winston_one

Yes, we can't use pure Pb PROCESS. And as I say we will not use it anyway, as we have lead-free BGA's, LGAs, component with Solder Charged Terminations... It's became almost normal practice to solder it with leaded solder pastes. In this case peak re

paste Sn42/Bi58 and Lead Finish

Electronics Forum | Tue Nov 06 22:37:35 EST 2012 | davef

Ryan ... "As for bismuth-based lead-free alloys, a lower melting temperature than that of tin-lead is offered together with a cost similar to that of tin [in the area of $3/lb]. Unfortunately, bismuth in soldering alloys tends to create embrittlemen

Re: High temperature solder paste for gold plated MCMs

Tuan - One of the reasons I suggested pre-tinning (aside from the negative effects of Gold on appearance and reliability) is the known slower wetting of Sn/Ag and Sn/Cu alloys as compared to Sn/Pb. If you don't have to be Lead-free, the high Lead

Solder bath temperature

Electronics Forum | Thu Jan 26 13:13:14 EST 2017 | dyoungquist

What type of solder are you using, Lead or Lead-Free? What is the melting point of it? What temperature are you setting your solder bath to? Possible solutions: 1) Give your solder bath a little more time to even out the temperature across the en
