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......

inSMTIt's a waste to throw away the unused solder paste in the surface mount technology. The next time you use another type of solder paste for the surface mount, can these two types of solder paste be mixed together for use? Here, the solder paste manufacturer will explain to you: Can leaded solder paste and lead-free solder paste be mixed and used? Here we will start with the basic components of solder paste. Generally, solder paste can be divided into two types: leaded and lead-free. In layman's terms, leaded solder paste means it is rich in lead.P)The solder paste. Lead-free solder paste is also called......

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......

inSMTDuring the processing and production of surface mount technology (SMT) patches, many undesirable phenomena may occur, one of which is the stele erection phenomenon. The term "erect monument" literally means that electronic components stand upright like tombstones, which is very vivid. That is, when electronic components are printed or surface mount, they will stand upright. Below, Shenzhen JJY Solder Paste Manufacturer will share with you the reasons for the occurrence of monument erection during surface mount technology (SMT) processing:1Insufficient mounting accuracy is generally inSMTIf component offset occurs during surface mount, surface tension will be generated during reflow soldering due to the melting of solder paste......
