Features of the use of soft solders
When choosing the optimal brand of soft solder, its following technological characteristics are taken into account:
Wettability. The essence of the phenomenon lies in the fact that the melt must completely spread over the surface of the soldering zone, filling all the gaps densely, and not forming cracks. This can be done only when the metal of the solder has the reliability of the bond between the molecules of a solid greater than in a liquid one;
Melting temperature. It should be higher than the temperature of the constant operation of the solder joint, but lower than the temperature of the blanks to be joined. An important characteristic of any solder is the actual range of temperatures of its crystallization — between the beginning of the melting of the alloy and its complete transformation into a liquid. Only after the complete solidification of the solder brazed joint can be subjected to the necessary load, otherwise fragility and increased electrical resistance can cause destruction of the soldered joint;
Toxicity. In the composition of solder, a minimum of toxic substances must be established, which include zinc (its vapors are poisonous), lead and tin powder.
Electrovek-steel Company offers to buy at reasonable prices from manufacturers soft solders tin-lead and tin-copper-zinc basis. The supplier guarantees the timely delivery of products to the address specified by the consumer.
