Nowadays, soldering technology operates well in various industries of electronic products, and at the same time, soldering technology has also created higher-density processes. The sub-components can be firmly fixed on the circuit board. High-quality solder wire can effectively enhance the performance of the solder wire. Therefore, when purchasing solder wire, we need to carefully select to choose high-performance and excellent solder wire. Now, how should JJY solder paste manufacturer choose a suitable oneTin wire:

weldingHow to choose tin wire?

1Look at the appearance:

Visual inspection: Good tin wire should be smooth, lustrous, free from oxidation and blackening! High-quality solder wires are all protected by a layer of film to prevent oxidation. Generally, the quality of solder wires is better when they are shiny in color. Dark solder wires have a higher lead content and are relatively less likely to melt. The color of good solder wire is shiny (leaded), or silvery white (lead-free), rather than white.

2Touch by hand:

Good solder wire is white and shiny, and it is not easy to apply it to your hands when wiped by hand. However, solder wire with a high lead content is black and it is easy to make your hands black when wiped by hand! Tin has good ductility. The higher the purity of the tin wire, the less likely it is to break. Of course, tin wire with a high tin content is very soft by itself and does not belong to hard metal products.

3Wettability:

Judging from the wetting performance. As for lead-free solder wire, it depends on whether it compliesROHSIt can be judged by the standard, flux residue, halogen-free and soldering speed. Smoke, spatter, residue and brightness are also criteria for judging the quality of solder wire.

4Packaging:

Pay attention to the packaging appearance of the solder wire. Although the packaging appearance does not represent the quality, all solder wires produced by regular manufacturers will have corresponding detailed labels. If there are quality problems, they can be better verified. The product label should indicate the basic information that the solder wire should have, such as the tin content or degree, lead content, flux content, melting point, and packaging weight.
Brand:

Choosing a solder manufacturer is the best way to ensure quality. Many friends, for the sake of convenience, often go to nearby electronics cities or hardware tool stores to buy solder wire. And these stores, as distributors, must make money. It can be imagined that their profits lie in the price difference. Therefore, when we make purchases, we should try to buy directly from the manufacturers.

5Solder wire price
How much is a roll of solder wire? The price of a roll of solder wire consists of several aspects. One is the weight. A roll of solder wire varies in size, with some being too small100Of the University of Cambridge800The gram, so the price is different in terms of weight. The other one is the degree (which is what people often call the tin content)/The higher the tin content, the higher the price. (The tin content of lead-free is.99%The above, the tin content is from10%-99%The prices are all different. The calculation of the price of eco-friendly solder wire is a bit different. The tin content of eco-friendly solder wire is all the same99%The above is basic.100%Well, the eco-friendly solder wire is approximately800G/Volume.

6Shelf life of solder wire
Solder wire, due to the addition of flux in the middle, can be stored for a long time if the soldering effect is not a concern. However, its surface will oxidize, and once oxidized, it will affect the soldering effect. It is better to order as much as needed and buy more when it is used up. The shelf life of solder paste is6For a month, it needs to be there6Use within one month.
