What are the differences between lead-free solder paste and leaded solder paste? Generally speaking, the ingredients of solder paste are different, and so are their melting points. Nowadays, many products in society must have a combination of solder paste/Welding materials. In many industries, lead-free solder paste is mostly chosen to replace the previous leaded solder paste. This is because people's awareness of environmental protection is getting stronger and stronger. What are the differences between the two and how to distinguish them? Let's talk about it with JJY Factory: Leaded solder paste and lead-free solder paste have different colors.......

The application of lead-free solder paste in electronic products and how to choose high-quality solder paste? Nowadays, the pace of society is constantly advancing. Electronic devices such as mobile phones, computers, laptops, and smartwatches have become indispensable products in people's lives and work. These products are basically composed of circuit boards. Electronic components such as resistors, capacitors, diodes, and integrated circuits are closely combined with the circuit board through solder joints formed on the circuit board by solder paste. Realize the electrical connection function between components......

What does "no-clean" mean? What is no-clean solder wire? At present, the no-clean soldering process is increasingly widely applied in related fields of the electronics industry. As a supporting process material product for lead-free tin wire, it has also been continuously developed and improved. To ensure that electronic equipment is not cleaned after soldering, soldering has high equivalence and reliability. Now, let's have a look at it with the help of the editor from JJY:What does "no cleaning" mean? After soldering with ordinary solder wire, there is a lot of rosin residue at the edge of the solder joint......

Is lead-free solder wire really lead-free? What are its standards,Generally, if we classify solder wires according to the metal alloy materials, they can be divided into tin-lead alloy solder wires, pure tin solder wires, tin-copper alloy solder wires, tin-silver-copper alloy solder wires, tin-bismuth alloy solder wires, tin-nickel alloy solder wires and solder wires made of special tin-containing alloy materials. Therefore, there are distinctions when making judgments. The surface of lead-containing solder appears bright white. Lead-free solder is light yellow. By hand......

How to choose low, medium and high lead-free solder paste? Nowadays, many solder paste manufacturers choose from. In the soldering industry, there are certain differences in solder paste formulas, production processes, and types. Among them, lead-free solder pastes are roughly divided into low-temperature solder pastes, medium-temperature solder pastes, and high-temperature solder pastes. So many people will screen these several types. Each one has different process conditions. So where are the specific characteristics and differences? The editor of JJY summarizes them for you as follows: Low-temperature solder paste:......
