  2. Solder - Wikipedia

    en.wikipedia.org/wiki/Solder

    When lead-free solder is used in wave soldering, a slightly modified solder pot may be desirable (e.g. titanium liners or impellers) to reduce maintenance cost due to increased tin-scavenging of high-tin solder. Lead-free solder is prohibited in critical applications, such as aerospace, military and medical projects, because joints are likely ...

  3. Soldering - Wikipedia

    en.wikipedia.org/wiki/Soldering

    The solder used in the process can vary in composition, with different alloys used for different applications. Common solder alloys include tin-lead, tin-silver, and tin-copper, among others. Lead-free solder has also become more widely used in recent years due to health and environmental concerns associated with the use of lead.

  4. Solder alloys - Wikipedia

    en.wikipedia.org/wiki/Solder_alloys

    Soldering copper pipes using a propane torch and a lead-free solder. Solder is a metallic material that is used to connect metal workpieces. The choice of specific solder alloys depends on their melting point, chemical reactivity, mechanical properties, toxicity, and other properties.

  5. Wiped joint - Wikipedia

    en.wikipedia.org/wiki/Wiped_joint

    The solder grade used for leadworking is plumber's solder (80% lead / 20% tin). [ i ] Although this is thought of as a high melting point solder amongst lead-tin solders, the solidus is relatively constant for all of these solders and it is the liquidus which climbs from the eutectic point at Sn 63% / Pb 37%.

  6. Wave soldering - Wikipedia

    en.wikipedia.org/wiki/Wave_soldering

    The Restriction of Hazardous Substances Directive (RoHS) has led to an ongoing transition away from 'traditional' leaded solder in modern manufacturing in favor of lead-free alternatives. Both tin-silver-copper and tin-copper-nickel alloys are commonly used, with one common alloy (SN100C) being 99.25% tin, 0.7% copper, 0.05% nickel and <0.01% ...

    en.wikipedia.org/wiki/Dip_soldering

    The most common dip soldering operations use zinc-aluminum and tin-lead solders. Solder pot metal: cast iron or steel, electrically heated. Bath temperature: 220 to 260 °C (for binary tin-lead alloys) or 350 to 400 °C (for lead-free alloys) Solder composition: 60% Sn, 40% Pb or eutectic alloy.

    The phenomenon was discovered by telephone companies in the late 1940s and it was later found that the addition of lead to tin solder provided mitigation. [6] The European Restriction of Hazardous Substances Directive (RoHS), which took effect on July 1, 2006, restricted the use of lead in various types of electronic and electrical equipment.
