Silver Solder, Lead Free Solder . . . .

Discussion in 'Electronic Basics' started by Ramendra S Roy, Feb 11, 2006.

  1. Hi!
    I have read a few posts and the response to them on the safety of
    solders carcinogens etc on this group. Interesting.
    What I am asking is - silver solder is more readily available these days
    and so is lead free solder. Do all lead free solder have silver content?
    Does silver solder have a higher mp?
    I am about to buy a soldering iron with a finer tip than what I have. I
    cannot splash out too much for a temperature controlled one just want to
    get the best my money can buy. Now, I have noticed 'lead free' soldering
    irons. The given data along with them says tips tinned with lead free
    solder. Anybody has any more data?
    Thanks in advance for any enlightment.
    Ramendra

    I dont know much about your solder questions but in regards to you
    buying a new iron, I bought a Weller WESD51 from

    http://www.hmcelectronics.com/cgi-bin/scripts/sub/Weller/90/1/

    for just hobbyist stuff and am very pleased with it. It may cost more
    than you want to spend but is by no means a bank breaker. There is
    also a nice non-controlled iron there for about $40 US. I am by no
    means affiliated with Weller or the website, I just thought I would let
    ya know.

    No. There are many different alloys available.

    Than what? Silver has a higher melting point than either tin or lead,
    so alloys of tin lead and silver usually have a higher melting point
    than alloys of just tin and lead, but it depends a lot on how much
    silver is in the alloy.

    In what country are you making this purchase?

    They are available for well under $50.

    How much money are you willing to spend?

    They are trying to tell you that if you are working a lead free
    production line, it will not be momentarily contaminated with the
    tinning (solder coating) on the tip of the new iron.

  4. Thanks fot your replies.

    The lead free silver solder that I can get here in the UK from maplin
    has 4% silver.

    I am buying the soldering iron in the UK also and budget is around £20.
    I am not a professional - just DIY for fun and satisfaction.

    I was asking about the melting point only because I do not consider
    myself an expert solderer and even though my circuits seem to work - am
    concerned about destroying components because I take too long to solder
    connections. Therefore - higher melting point - greater chance of
    toasting the component etc..

    Thanks for your ideas.

    Unless you are repairing some alaready lead free joints, stick with the old
    tin/lead solder and save yourself a bunch of trouble. The lead free stuff
    does not work very well.

    If you are not soldering products for sale, why are you using lead
    free solder? The easiest to use alloys are 63% tin, 37% lead, and 62%
    tin, 36% lead, 2% silver.

    The higher temps involved in lead free soldering actually make a
    thermostatic iron more important.

    You might actually be well advised to continue using 'proper' solder. Lead
    free has many issues - not least its lack of wetting ability. Classic
    tin/lead solder will continue to be available since it's needed for
    mainteance reasons ( not to mention those who managed to get an exemption )
    ..

    You seriously don't *want* to use lead free. No one in their right mind
    would. Failure rates of equipment are already increasing as it's phased in.
