![]() Using silver alloy solder will leach out the joint, giving it a brittle and weak joint. ![]() Silver was added to the alloy to prevent silver migration when silver-plated components are soldered. The silver alloy solder could be a combination of lead or no lead at all. Either ingestion or inhalation brings about all these health risks. Possible health effects are reproductive problems, digestive problems, muscle pain, joint pain, and concentration problems. Wrongful handling of lead in a soldering environment may lead to exposure to lead fumes. The container needs around 380 degrees Celsius to melt and may take seconds longer to cool, leaving shiny and clean solder joints. It is thought to form stronger joints than the lead-based solder because naturally, tin is solid and hard. However, lead-free solder has a higher melting point and is difficult to work with but better if you consider the health issues related to lead poisoning. Several standardization bodies require that we use lead-free solder because of the dangers posed by information. Lead is poisonous when inhaled for a long time, and that is why the European Union is encouraging you to think about alternatives to lead-based soldiers. The tin in this alloy mixture lowers the melting temperature because the circuit boards are sensitive to high temperatures. The melting temperature for this compound is between 180-190 degrees Celsius. It contains a mixture of tin and lead in a percentage of 60/40. The lead alloy solder has been an industry standard for a long time. 2.1 Best Solder For Circuit Board- The Lead-based Solder The defining difference between the three is the melting temperature from this difference and the kind of work at hand, choose the one that appeals to you. The three significant categories of solder suitable for your circuit board: Next, we’ll take a closer look at the solder used for the board and the differences. The type of solder used in electrical bonding contains different materials, with the most common one composed of 60% tin and 40% lead, thus the name 60/40 solder.
