    I am planning to use lead-free solder. Are there any problems that people
    have encountered using lead-free solder? Will a 60W soldering iron provide
    enough heat to melt it?

    Any advice and suggestions would be greatly appreciated.

    Hi Charles,

    I do warranty repair work for Kenwood who now insist on lead free
    solder for their products.

    Requires more temp on the pcb pads which can be a bit risky sometimes,
    Existing 60W will be ok with temp wound up (you will go through more
    tips though), Careful attention to clean surface preparation for each
    joint will be required (Just like back in tech again).

    A good joint wont be clear and shiny like it is the lead - expect them
    to look dull but be physically well formed.

    I'll continue to use lead for all work other than warranty work which
    expressly requires Lead Free Solder.

    Cheers,
    Sam T

    Wattage don't enter into it. It's the temperature. There are a number of
    (largely incompatible) types of lead free solder. All of them (AFAIK)
    require a higher *temperature* than standard tin-lead solder. So you'll
    need to either turn the temp up to what's required for the particular lead
    free alloy you're using (or change to a hotter tip if you're using, say an
    old Weller TCPN iron). Also be sure that the components you're using are
    rated to the higher temperature. Could be a bit embarrassing if the
    internal wires on a component desolder themselves as you're soldering the
    thing onto to a board.

    Cheers,

    Is that like lead free bullets, DU?

    defeats the purpose if the components aren't lead free as well. (apologies
    to the OP whom i accidentally emailed this reply to)

    Yes, we must stop children eating solder and leaded components and
    drinking leaded petrol. Let's kill them all with DU instead. Been
    fairly effective in Iraq.

    Lead is only a problem if it is in your blood stream. So who'se been licking
    their solder joints and forcing the legislative change? C'mon own up.

    Don't forget we are a lot safer now that we don't have leaded fuel, we
    replaced it with higher Dioxin level petrol. At least when more people get
    solid body cancers the "do-gooders" can be happy they save the thousands of
    people from getting lead poisoning before, oh hang on, I can't remember of
    an epidemic of lead poisoning, oh well.........

    yeah, but have you seen the study relating childhood leukaemia to living
    beside petrol stations - 7x ~ 15x, pretty staggering numbers.

    I once went to a health & safety meeting, which the *entire* company was
    forced to attend. A roll was taken, and we each had to signb a document
    stating we had been warned of the hazard, and promised not to do it. The
    hazard? chewing eutectic solder.... the production manager suggested
    people should chew cable ties, they are a lot less toxic...

    "Dingo" - ratbag is closer to the mark

    ** The problem is when the gear is eventually dumped - the lead leaches
    out into the environment.


    ** The benefit to small children are well worth it.

    But a raving fuckwit like " Dingo" has no clue and no interest in that.

    Probably his brain was lead fucked as a toddler.

    I remember reading somewhere that the whole lead-free thing in Europe is
    an overreaction in the case of electronics. Apparently the lead
    contributed from electronics is only about 10% in landfill. The EU
    bureaucrats are having a whale of a time though. They are huge
    benefactors of any regulation, like Sir Humphrey.

    Benzene is a brain toxin and known carcinogen. Toluene is a brain
    toxin. Both are in all petrol so I reckon the leaded issue was blown
    out of proportion and as time passes less vehicles would require
    leaded so they could have left at least one pump where older cars
    could fill with high octane leaded.
    My brain was fucked from petrol sniffing as a mechanic. ark ark ark..

    but your above mentioned components of petrol are not heavy metals, and
    are not part of solder. - - off topic.

    lead is not just found your blood but stored in other body tissues
    including the brain, where the function is impaired.

    btw. LRP pumps can be found at most petrol stations.

    and if you want some free DU go to the visitors centre at lucas hieghts
    reactor -sydney, and chew on the sample they let you play with

    quantity in modern autos. In the US, even more stringent laws apply, where
    even a seal is made when filling the tank. This is long overdue in
    Australia.

    atmosphere. Lead is a very dangerous poison. It's effects on the human body
    are pernicious, persistent and widespread. It's removal from Australian fuel
    was many years overdue.

    So what? Do I give a ****, nOOOOO
    So what, it isn't leaded fuel.
    I guess you don't watch SBS. Contamination and birth defects DU has
    caused in Iraq.

    When it's part of your job and also you can't protect yourself from
    others misuse unless you leave the trade. Piss poor situation really.
    Did you know they don't have to put a warning on petrol unless the
    known carcinogen benzene is greater than 5%?
    Back in the 70's washed parts at a Gov dept with toluene/toluol a
    suspected carcinogen and now, known brain toxin.

    That's proof that kids were stupid before they ingested lead paint.

    Thankyou to all who responded to my post.

    I actually bought some lead-free solder and tried soldering on some copper
    stripboard with a Weller 240V 60W soldering iron. It didn't go too well I
    must say.

    All this *un* stuff is a bit sus.
    copper + silver + tin doesn't do the job as well as regular tin lead
    solder. Why am I not surprised?
