How should lead-free tin wire be purchased and selected? JJY Solder Paste Manufacturer

Lead-free tin wireHow should it be used? Nowadays, lead-free solder wire is also known as solder wire. In a rapidly developing era, it has made a significant impact on the industry and is available in many electronic manufacturing plants. However, some people are now asking how to use solder wire properly and how to choose when purchasing. JJY solder Paste Manufacturer can explain this to everyone:

I. Look Estimation and inspection: Good tin wire should be smooth and lustrous, without oxidation or blackening.
The quality of solder wire is generally good when it has a lustrous tone. Dark solder wire has a higher lead content and is relatively less prone to melting. 

Ii. Touch Good solder wire has a lustrous white color and is not easy to stick to your hand when wiped by hand. However, solder wire with a high lead content turns black and is very likely to cause black fire when wiped by hand! Tin has excellent plasticity. The higher the purity of the tin wire, the less likely it is to break.

Naturally, tin wire with a high tin content is very loose by itself and does not belong to hard metal products

 Iii. Wettability  It can be judged by the wetting performance characteristics. However, the absence of heavy metal solder wire depends on whether it meets the requirementsROHSIt can be judged by the standard, solder paste residue, phthalates and tinning rate. Thick smoke, splashes, residues and color are also criteria for judging the quality of solder wire.

Iv. Packaging  Pay attention to the packaging appearance of the solder wire. Although the packaging appearance does not necessarily indicate the quality, any solder wire produced by a reliable manufacturer will have relatively detailed marks. If there are any quality issues with the product, it can be better verified.

V. Well-known Brands  Choosing a solder wire manufacturer is the best way to ensure quality and quantity. Many friends only seek convenience and usually go to electronic cities or hardware tool stores based on the principle of proximity to purchase solder wire.
  As an agent, such stores must make money. It is obvious that their profits lie in the price difference. Therefore, when we purchase, we should try to choose the manufacturer and buy immediately.
