Soldering station - the difference between lead-free solder wire and silver-containing solder:
1. Different melting points: Due to the different metal alloys, the melting points are also different. The melting point of silver-containing lead-free solder wire is 217 degrees, while the melting point of lead-free solder wire is 227 degrees. The difference is about 10 degrees.
Second, the metal composition is different: silver-containing lead-free solder wire is composed of tin-silver-copper alloy, while lead-free solder wire is composed of tin and copper alloy, and does not contain silver metal components.
3. The cost is different: due to the high price of silver metal, the cost of silver-containing lead-free solder wire is more expensive than that of lead-free solder wire. This is the biggest advantage of lead-free solder wire. The higher the silver content in silver-containing lead-free solder wire, the more expensive it will be.
4. The overall performance is different: due to the action of silver metal, silver-containing lead-free solder wire is better and stronger than lead-free solder wire, and the solder joints are stronger. Secondly, electrical conductivity is also a very important indicator in solder joints. Silver is a metal with good electrical conductivity, so silver-containing lead-free solder wire has better electrical conductivity and thermal conductivity than lead-free solder wire. These properties are unsurpassed by lead-free solder wire.
5. The gloss color of the solder joints is different: the gloss of the lead-free solder wire presents a certain brightness, and the appearance is better. This is also one of the advantages of lead-free solder wire, but the glossy color of the solder joint does not represent the soldering performance of the solder joint itself. The gloss color of silver-containing lead-free solder wire solder joints affects the brightness and color of the appearance of solder joints. Since silver metal is a dull metal, not a bright metal, the solder joints of silver-containing lead-free solder wire are not bright, but dull.
