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......

Most electronic circuit board manufacturers encounter some problems to a greater or lesser extent when using solder paste for soldering. For instance, problems such as false soldering, fake soldering, solder balls, sharp edges, yellowing, and blackening have been bothering many people. Today, JJY Solder Paste Manufacturer will focus on discussing with you the causes and countermeasures of yellowing and blackening of solder paste: 1. The causes and countermeasures of yellowing of solder paste after soldering:1When solder shows color, it is generally closely related to temperature, such as the temperature of the solder......

inmtIn the surface mount technology (SMT) processing of the factory, solder paste is a very important part, located inSMTThe top of the processing production line. Only when the solder paste is fine can it be ensured that there will be no major problems of various kinds in the subsequent surface mount processing and production. Below, the solder paste manufacturer will introduce to you the usage of solder paste in the production process. I. Manual Welding:1Before processing, the solder pads need to be wiped clean without any residue. Then apply solder paste and proceed with soldering using a soldering iron or hot air gun......
