In Russia, wire solder and liquid flux are traditionally used for manual soldering. Despite the “tradition”, the reliability of the seams will significantly decrease if the flux is not washed (and, as a rule, not all residues of the liquid flux get into the heat treatment zone). With tubular solders that do not require cleaning, this problem will not arise. In all developed countries of the world, solders with a flux inside have long been produced. On the domestic market, the greatest demand was established for tin-lead solders.
When choosing products of this category, preference should be given to specimens with a large number of flux channels. This characteristic has a positive effect on the uniformity of the distribution of the flux along the length of the bar (without "blind" zones). When working with single-channel solders, you will be deprived of such an advantage: you will have to solder "dry", i.e. without flux. In addition to the increased productivity, the obvious ease of use speaks in favor of using multichannel solders.
Our website provides comprehensive information on this issue (comparative table of alloys and fluxes, advice on selection and use, etc.), so if you need tubular solder , feel free to contact us. To begin with, we note that the solder is selected based on the required strength of the joint, the physicochemical characteristics of the metals to be joined, the price and corrosion resistance of the alloy. It is worth knowing that the specific conductivity of the solder is of great importance when soldering the so-called. live parts.
Solders are used in various fields: from structural products to electronic devices. In our catalog you will find solders of different diameters, with different types of flux and different percentages. For the production of modern high-quality solders, alloys with a minimum of impurities (and compliance with the international conclusion ISO 9453) are used, which meet international rules from J-STD-006A to QQ-S-571E. The name of the alloy and the amount of impurities in a strict order must be indicated on the certificate of a specific batch of solders.
The optimum diameter of the solder for soldering surface mount parts ranges from 0.46 to 1 mm. When soldering very tiny chip parts, solders with a diameter of 0.46-0.56 mm are used.
Tubular solders with a high wetting rate, high efficiency, meeting the most stringent strength requirements, you can always find in the Ostec catalog: www.ostec-materials.ru/materials/dlya-sborki-elektron/new-pripoi-trubchatye.php .
