In today's economic development of the market, the electronic technology market is also gradually expanding, solder widely used in electronic products also enjoy the dividend of The Times. Solder wire products on the market are mushrooming, lead-free, different formulations of different materials, for beginners in the electronic industry to choose a suitable tin line is also a headache. This article will introduce the difference between lead and lead - free solder wire.

First, solder wire can be divided into lead and lead - free two categories. So is the higher the tin content, the better? Not absolutely, what you need to do is to understand the nature of your product and the target audience.

Why do you say that? Only the solder material with the highest degree of fit to the product can weld the best finished product. For example, some products have low heat resistance, so choose lead tin line Sn63Pb37 (melting point 183℃) and lead-free low temperature tin line (melting point 138℃) is very good; And then the user group, because the tin itself is valuable, the higher the tin content, the higher the cost, so generally only export or environmental requirements will use lead-free products. If you want to choose lead tin wire, it is recommended to find Sn63Pb37 lead solder wire, which is the best ratio of lead tin wire at present, and the melting point is low.

So there is no best solder wire, only the most suitable. If there are more questions welcome to consult us, we will answer for you.
