SometimesSMTIn surface mount technology (SMT) processing, there is an annoying poor processing phenomenon, which is false soldering. The manifestation of false soldering is generally on the surfaceSMTSurface mount components are soldered to the pads, but in reality, they are not perfectly integrated. After going through various complex processing techniques in electronic processing, a kind of poor soldering phenomenon is very likely to occur. There are generally two specific reasons for the formation of false soldering. One is thatSMTDuring the processing, due to improper processing and production techniques......

inSMTSolder paste printing is a crucial processing step in surface mount technology (SMT) processing, and it plays a significant role inSMTThe processing is a relatively early production process and also a place prone to poor processing. Many poor problems in surface mount technology (SMT) processing are caused by errors in solder paste printing. Now, JJY Solder Paste Manufacturer will introduce to you the problems in solder paste printing:1. Causes of sharpening: It might be due to gaps in the scraper or excessive viscosity of the solder paste. Avoid or solve......

inSMTSolder paste is an indispensable processing material in the turnkey surface mount technology (SMT) processing. Solder paste, also known as solder paste, is a new type of soldering material, mainly used forSMTPatch. It is generally a paste-like mixture composed of surfactants such as welding powder and flux, as well as thixotropic agents. DifferentSMTDifferent solder pastes will be used in processing requirements. So, what types of solder pastes are there? Here, the Shenzhen solder paste manufacturer will briefly share with you the types of solder paste: 1. Whether it contains lead in electricity......

When it comes to lead-free solder paste, it is relatively more popular among people. As people increasingly pursue environmental protection, the emergence of lead-free solder paste can be said to meet people's environmental protection requirements. However, lead-free solder paste is not completely without drawbacks. One of the disadvantages of lead-free solder paste that everyone may know is that it dries very easily. Now, let's explain it from JJY solder Paste Manufacturer: There are mainly two reasons for lead-free solder paste to dry out: First, for example, if the formula is not good or the temperature is too high,......

After soldering with lead-free solder paste, you may find that the circuit board after soldering is not as smooth as you imagined and is granular. What is the reason for this? Today, the solder paste manufacturer will introduce to you the reasons why lead-free solder paste is not smooth after soldering: The main reasons for lead-free solder paste not being smooth after soldering are as follows:1If the solder paste is preheated for too long, the flux will evaporate, causing the solder paste to be oxidized by the air before it is completely melted. As a result, there will be particles in the soldered product......
