Technical characteristics of tin solders

Tin-containing solders are called soft solders with a melting point not exceeding 300°C. Hard solders have a melting point above 300 °C. The mechanical properties of the soldering material are in the range 50...70 MPa, so that the soldering process can be carried out by normal immersion in the molten metal. Supplier Evek GmbH offers to buy any solder at an affordable price in a wide range. We provide delivery of products anywhere in the continent. The price is optimum.

Alloy PIC

Purely tin solder is not made soldering, and use a variety of tin-lead alloys, which contain from 10 to 90% of tin (the rest is lead). Marking of these alloys is PIC (tin-lead solder), followed by a number that indicates the percentage of tin. For example, in the alloy POS 90 90% is tin and 10% is lead. The main technological impurity in these low-temperature alloys is antimony. Because lead promotes severe corrosion, tin-lead solders are not used for soldering light alloys. Tin-lead solders have a lower melting point than tin or lead. When selecting a solder grade, it is important to note that lead is toxic.

Tin solder technology

The melting point of low-temperature brazing alloys containing tin is 183°C and (depending on the chemical composition of the solder) the melting point ends at 183°C:

PIC grade. Liquidus temperature (complete melting)
15 280 °C
25 260 °C
33 247 °C
40 235 °C
60 191 °C
90 220 °C

When using the soldering technology with tin solder, it must be taken into account that the solder layer must not be too thick, otherwise the soldering speed slows down. The thickness of the solder is also determined by the amount of flux used to remove the oxides formed during the soldering process. Here the solder acts not only as a connector of parts, but also as a protective coating, providing the soldered seam area from the access of air oxygen there.
