Low-temperature tin wireIt is a type of solder wire. However, solder wire is mainly composed of two components. One type of solder wire is calledEutectic solderingIt's tin.63And lead37What are the differences in the composition of solder wires? JJY is here to share with you.

  Solder wireIts melting point is183℃If the melting point composition of tin is higher than63%Then, as the melting temperature rises, its compressive strength will gradually decrease. On the contrary, when the tin content is lower than10%Then, during welding, this compressive strength is poor, and the joint will also become brittle very quickly.

  Eutectic solder is in a good state below the wetting range of the soldering material. However, at the eutectic temperature, the solder will change from solid to liquid, and during this process, it does not need to go through a semi-liquid state.

  When melting, the temperature of eutectic solder is slightly lower than that of non-eutectic solder. In this way, it is equivalent to reducing the damage to the components being soldered during electric soldering. In addition, because eutectic solder changes from liquid to solid very quickly, it also greatly reduces the situation of empty soldering.

  Most of the time, in227℃The solder raw materials that fluctuate up and down will not have a significant difference in the melting point of the solder wire. Therefore, when applying solder wire, it is necessary to first test the temperature that the soldered components can withstand, and then consider selecting solder wire with an appropriate melting point or low-temperature solder wire.

  At present, the commonly used solder wires can be roughly classifiedLeaded solder wireThere are two specifications of solder wire and solder wire, but there are differences in main parameters such as melting point, for example, low-temperature solder wire.
