How to stir lead-free solder paste correctly? Many people (or the industry generally believes) believe that solder paste stirring is to evenly mix the solder paste and solder powder in the solder paste. In fact, the stirring of solder paste is to obtain the appropriate printing viscosity,We know that due to its certain thixotropy, the actual viscosity of solder paste during the printing process is different from that in its static state,The best printing effect of solder paste is achieved within a certain range of viscosities,If the solder paste is printed directly without stirring......

Can lead-free solder paste still be used after its expiration date? What should I do if the solder paste has expired? Many people would ask such a question: The shelf life of solder paste is generally6Can solder paste still be used after its expiration date in a month? What impact will it have on the product if used? How long after the expiration date can solder paste be used at most? And in the case of most companies, how to put it? It depends on the company's requirements. Some companies strictly follow strict control methods, and those that have expired will be scrapped and disposed of. The male......

What are the advantages of silver-containing lead-free solder paste? Nowadays, society is increasingly inclined towards environmental protection, and it is also clear that the price of silver in society is relatively higher. Then some people ask, given the high price of silver, what is the purpose of adding it to lead-free solder paste? Now, let's have the editor of JJY Solder Paste Factory explain it to you:1Lead-free solder paste containing silver has better electrical conductivity. Silver has the best electrical conductivity among metals. Adding silver to lead-free solder paste can increase the solder paste......

What are the advantages and disadvantages of low-temperature solder paste? The main reason for the application of low-temperature solder paste is that the product design cannot withstand the conventional temperature requirements and uses low-temperature solder paste for the soldering process. It serves to protect the components that cannot withstand high-temperature reflow solderingPCBVery much.LEDIt is welcomed by the industry. Its alloy composition is tin-bismuth alloy. The peak temperature of reflow soldering for low-temperature solder paste is170-200℃. Low-temperature flux paste is a no-clean type of flux designed for the current rapid welding production process......

How can the impact of solder paste splashing be minimized? Generally, in the production process of solder paste, waste is inevitable, which means issues related to the quality and reliability of the product as well as the manufacturing process. Other types include water stain contamination and flux splashing. These effects are relatively minor, but due to solder spatter, the solder has actually wetted the surface of the "gold finger". Now, let's have JJY solder Paste Manufacturer explain to you: There are many reasons for solder spatter, and it's not necessarily reflow soldering......
