How to choose a lead-free solder paste manufacturer

Nowadays, with rapid development and increasingly fierce competition among manufacturers, many people don't know how to choose. Personally, I think it depends on different needs. Domestic solder pastes each have their own advantages. There is no best one, only the most suitable one. There are only a few good lead-free solder paste manufacturers. You can consider JJY. They have over twelve years of experience in this industry, offer a wide variety of products, and have excellent performance. BelowSolder paste manufacturerExplain:

1, Environmental Protection

The environmental protection mentioned here refers toROSHThe standard, which is what we often refer to as the choice between leaded solder paste and lead-free solder paste, or even halogen-free solder paste; Many export products need to pass throughROSHTherefore, when choosing raw materials, all must meet this standard; otherwise, the products cannot be exported to the target country. If there is such a requirement, leaded solder paste will not be taken into consideration. If it does not need to pass this standard, the range of choices will be much larger.

2Melting point

The melting point of solder paste varies greatly depending on its alloy composition. Because some components that need to be soldered cannot withstand excessively high temperatures, some solder pastes with relatively low melting points are required. Here are several solder pastes with relatively low melting points, such as lead-free low-temperature solder paste (melting point)138℃Lead-free medium-temperature solder paste (melting point.172℃Leaded solder paste (melting point.183℃"

Some products need to operate in high-temperature environments, so their melting points are required to be higher. Here are several types of solder pastes with relatively high melting points, such as lead-free solder paste (melting point)217-227℃High-lead solder paste (melting point.280℃"

3Particle

Solder paste is a granular paste of metal powder. Its powder comes in many types. The smaller the particles, the more suitable it is for soldering precision components, which can prevent solder from coming together and causing adverse phenomena during the soldering process.

4"Clean"

The solder paste should be selected based on the cleanliness requirements of the product (printed circuit board) and different cleaning processes after soldering. When using the no-cleaning process, a no-cleaning solder paste with low halogen content and no strong corrosive compounds should be chosen. When the solvent cleaning process is adopted, solvent-cleaning solder paste should be selected. When using the water cleaning process, water-soluble solder paste should be selected.

5Price

Choosing the right product also requires an appropriate price. With the same performance, a lower price can make the produced product more advantageous. The quality of domestic solder paste products varies greatly. It is necessary to purchase from some manufacturers with strict quality control. The price of imported solder paste products from abroad may be a little higher than that of similar domestic products, but the quality can be well guaranteed. If you have higher requirements for solder paste, you may consider imported products from abroad.

When choosing a solder paste manufacturer, customers should consider multiple aspects. Production and delivery capabilities, R&D and design capabilities, technical support, quality and craftsmanship, after-sales service, etc. can all be criteria for evaluation. After all, we spend money to purchase products that satisfy us, making users feel at ease when buying and using them. This is our ultimate goal!
