inmtIn surface mount technology (SMT) processing, the flux in solder paste is indispensable. An appropriate flux can not only remove oxides and prevent the metal surface from re-oxidizing, but also improve solderability and promote energy transfer to the soldering area. Choosing high-quality fluxes is the secret to JJY building a reliable brand. Below, JJY solder Paste Manufacturer introduces three common fluxes to you:1Rosin type flux Rosin flux is the most common flux. Its soldering flux performance is relatively weak.......

SMTDuring the surface mount technology (SMT) process, everyone knows that one of the crucial steps is soldering with tin. If the solder on the solder joints is not full, it will have a very serious impact on the performance and aesthetic appearance of the circuit board. Therefore, it is necessary to avoid the situation where tin is not full as much as possible. Now, let's have a detailed introduction from JJY Solder Paste ManufacturerSMTWhat are the reasons for the incomplete solder coating in the surface mount? First, if the wetting performance of the flux used when soldering the solder paste does not meet the standard......

Solder paste ismtSolder auxiliary materials indispensable in the surface mount technology (SMT) process. According to environmental protection standards, it can be divided into lead-free solder paste and leaded solder paste. The melting point of solder paste is closely related to the composition of the soldering alloy. The following solder paste manufacturers have summarized the melting points of solder pastes made of different alloys as follows:The melting point of solder paste for tin-copper alloy is227℃; Tin, silver, copper3.0The melting point of silver alloy solder paste is217℃; Tin, silver, copper0.3The melting point of silver alloy solder paste is227℃; The melting point of tin-bismuth alloy solder paste is138℃......

Recently, some customers have inquired about what to do if they find the solder paste is too thin during the soldering process. Today, JJY Solder Paste Factory will give you a simple analysis. If the solder paste is too thin, it may lead to the inability to obtain good solder joint quality during the soldering process. The following are several possible temporary solutions to what to do if you find the solder paste is too thin:1Use a stirring rod or a dedicated solder paste mixer to thoroughly stir and mix the solder paste. This helps to evenly disperse the metal particles within it, making it......
