inmtIn the process, the setting of the furnace temperature curve for medium-temperature lead-free solder paste is a very important step, which directly affects the quality of the product. Therefore, it is very important to master the furnace temperature parameters of medium-temperature lead-free solder paste. Next, JJY solder Paste Manufacturer will talk about what exactly should be done? Under normal circumstances, the oven temperature for medium-temperature lead-free solder paste is180-230Between degrees Celsius, but the specific temperature setting should be based on the composition and viscosity of the material.PCBThe design of the plate and the welding process, etc......

Leaded solder paste is a type of solder paste that does not require cleaning. The proportion of tin is approximately63%The lead content is approximately37%. Solder paste is used for soldering electronic connectors, terminals, circuit boards and other components to achieve conductive connections and has excellent continuous printing performance. Less residue and good electrical conductivity; In addition, no-wash solder paste can offer various alloy compositions, different tin particle sizes and different metal contents to meet customers' requirements for different products and processes. Next, JJY solder Paste Manufacturer will tell you......

Nowadays, society is developing at an increasingly rapid pace, and the production of electronic products is becoming more and more widespread. The required product specifications and various requirements are relatively high, and there are also many types of products. Many people ask that there are many types of solder wires, and the common ones are leaded and lead-free. What are the differences between leaded and lead-free solder wires? Now, let's take a brief look at lead-free solder wire and leaded solder wire together with JJY Solder Wire Manufacturer: From the literal meaning, lead-free solder wire is a type of solder wire that does not contain metallic lead.P),One contains metallic lead......

Due to the differences in mechanical structure, function and application, the main purpose of an electric soldering iron is to solder components and wires. When we are doing solder wire soldering, we often encounter the phenomenon that the soldering iron tip does not stick to solder. How can we solve this problem? In fact, there are many reasons for the non-adhesion of tin. We can only look for these problems and solve them. Now, let JJY Tin Wire Factory tell you how to find the cause and the solution if this situation occurs: Generally, what will happen......
