SMTChoosing the appropriate solder paste based on different products and processes can effectively improve production quality for surface mount technology (SMT) factories. Below, Shenzhen JJY Solder Paste Factory will briefly introduce some common methods for selecting solder paste to you1Solder paste is generally classified into high, medium and low temperature solder paste based on temperature, and these need to be combinedPBCThe actual reflow soldering times of the board andPCBTake into account the temperature requirements of the components comprehensively.2The cleaning degree of the plates and the cleaning process after welding are the sameSMTstick......

When we are doing solder paste printing, sometimes we encounter the situation where the printing steel screen is blocked. Why is that? Today, JJY solder Paste Manufacturer will analyze it together with everyone:1The steel mesh was not cleaned thoroughly, with dust or debris. Once it comes into contact with solder paste, they will "clump together", causing the steel mesh to get clogged.2The opening design of the steel mesh is unreasonable. If the mesh is too small and there are too many burrs, it will cause the solder paste to be unable to be downloaded, thus resulting in mesh blockage.0.4itchThe openings of the steel mesh are relatively small. If the steel......

inSMTThe quality of solder paste printing during processing is also one of the factors that can directly affect the overall quality of the product, and inSMTMost of the soldering defects in surface mount technology (SMT) processing result from the quality issues of solder paste printing. In high-density and high-precision applicationsSMTThis is particularly evident in surface mount technology. Common solder paste printing defects mainly include insufficient solder, collapse, deviation, sharp edges, and uneven thickness. Below, JJY Solder Paste Manufacturer will briefly introduce some common factors that affect the quality of solder paste printing. I. Steel......

After the solder paste soldering is completed, we may find that the edges of the solder paste are not smooth, and there are burrs or stains on the surface. What should we do when encountering such a problem? Now, let's have the solder paste manufacturer explain it to you: First, let's analyze the root cause of this phenomenon: 1.PCBThe reason for the blurry formation of the board after soldering: The edge of the solder paste is uneven and there are burrs on the surface1Solution for low viscosity of solder paste: Replace the solder paste and choose one with an appropriate viscosity2Solution for rough walls of steel mesh holes......

SMTMany kinds of production raw materials are used in surface mount technology (SMT) processing, and solder paste is one of the more important ones. The quality of solder paste will also have a direct impactSMTThe soldering quality of surface mount technology (SMT) processing, and different types of solder paste also need to be selected for different production processes and products. Below, JJY Solder Paste Manufacturer will briefly introduce the common classifications of solder pastes to you: 1. Classification by solder paste ingredients1Leaded solder paste: It contains lead and poses a significant threat to the environment and human health, but it is used for soldering......
