inmtIn surface mount technology (SMT) processing, solder paste printing is a crucial process, which directly affects the quality of solder joints and the performance of electronic components. When solder paste printing, sometimes the problem of steel mesh blockage is encountered, which will affect the transfer and distribution of solder paste, thereby leading to soldering defects. So, what are the reasons for the steel mesh being blocked? Today, JJY Solder Paste Manufacturer will analyze with everyone the reasons why the steel mesh is blocked:1The steel mesh was not cleaned thoroughly. If there is dust or impurities on the steel mesh......

inSMTDuring the processing, the surface mount technology (SMT) processing factory sometimes encounters some poor processing issues, such as false soldering. This isSMTCommon processing defects in surface mount technology (SMT) processing. The following is a brief introduction by Shenzhen JJY Solder Paste Manufacturer on the common judgment methods and solutions for false soldering:I. Judgment of False Soldering1The online tester is tested by professional equipment.2Visual orAOIInspection. During the inspection process, the surface mount technology (SMT) processing factory found that there was too little soldering material at the solder joints or the solder wetting was poor, or......

SMTThe position of processing in electronic processing is becoming increasingly important with the development of miniaturization and precision of electronic products. There are also many points to pay attention to in the production process of surface mount technology (SMT) processing. If not careful, some processing defects that do not meet expectations may occur, and solder beads are one of them. The existence of tin beads is forSMTThe quality of surface mount technology (SMT) processing has a negative impact. At the very least, it affects the appearance; at worst, it may lead to poor bridging and other issues. Now, Shenzhen JJY Solder Paste Manufacturer will give you a brief introduction......

What is leaded solder paste? Superficially, it is not difficult to understand. Leaded solder paste, as the name suggests, is solder paste containing lead and is also known in the industry as leaded solder paste. It isSMTIndispensable welding materials in the surface mount technology (SMT) industry. Leaded solder paste is composed of a mixture of soldering flux components and alloy components. Tin and lead are the main components of alloys, and thus are called leaded solder pastes. Now, the solder paste manufacturer will explain to you: The composition of leaded solder paste depends on the type of solder paste. The alloy composition of leaded solder paste includes......

Flux paste is a paste-like flux made by mixing rosin and special chemical substances. It has certain activity and acidity, can remove oxides on the solder pad, prevent oxidation during the welding process, reduce the surface tension of materials and solder, improve wettability, and thereby enhance the reliability and quality of welding.BGAFlux paste is often used in chip soldering becauseBGAThe pins of the chip are hidden beneath the chip and solder paste is needed to help the solder flow to the pins. Flux paste is also fine......
