The melting points of solder used in the soldering industry vary depending on the composition of raw materials. When operating generally, the solders that can be selected include low-melting-point solders and high-melting-point solders. Here, the melting point actually refers to the temperature. So, what are the specific differences between these two types of solders that are suitable for different temperatures? Now, JJY Tin Wire Manufacturer will explain it to you:1The difference in the melting point of solder mainly depends on the different raw materials added, that is, the different alloy composition during the solder synthesis production process......

The phenomenon of poor tin penetration isPCBAIt is worth our attention. Whether the tin penetration is good directly affects the reliability of the solder joint. If the tin penetration effect is poor after wave soldering, it is easy to cause problems such as false soldering. Now, JJY solder Paste Manufacturer will give you a brief introductionPCBACountermeasures for poor tin penetration in wave soldering during processing: Requirements for tin penetration rate in wave soldering: The tin penetration rate of wave soldering points generally needs to be achieved75%The above means that the tin penetration rate of the panel appearance inspection should be higher than that of the board thickness75%The tin penetration rate is75%-100%......
