Technical specifications
Solders containing tin are referred to as so-called soft, for which the melting point does not exceed 300 ° C. to hard — above 300 ° C. Due to their mechanical strength, tin solders are considered to be soft: their strength is in the range of 50… 70 MPa, and the soldering process can be performed by the usual immersion of the materials to be connected to the molten metal.
Choice of solders
Pure solder solders are not soldered, but different tin-lead alloys are used, which contain 10 to 90% tin (the rest is lead). The marking of these alloys is PIC (tin-lead solder), followed by a figure that indicates the percentage of tin. For example, in the POC 90 alloy, 90% is tin, and 10% is lead. The main technological impurity in these low-temperature alloys is antimony. Since lead promotes intense corrosion, tin-lead solders for soldering light alloys are not used. Tin-lead solders have a lower melting point than tin or lead. When choosing a brand of solder, it is necessary to take into account that lead is toxic. Supplier Avlob offers to buy any solder at a bargain price. The price is the best in this segment of rental.
Application of tin solders
Melting of low-temperature soft solders containing tin occurs at a temperature of 183 ° C, and ends (depending on the chemical composition of the solder) at:
| Brand PIC | Melting point, ° C |
| 15 | 280 ° |
| 25 | 260 ° |
| 33 | 247 ° |
| 40 | 235 ° |
| 60 | 191 ° |
| 90 | 220 ° |
When using soldering solder brazing technology, it must be taken into account that the solder layer should not be excessively thick, otherwise the soldering rate will slow down. The thickness of the solder is also determined by the amount of flux intended to remove the oxides formed during the soldering process. Here, the solder acts not only as a connector of the parts, but also as a protective coating, providing a zone of soldered seam from accessing the oxygen of the air.
