inSMTIn the processing and production of surface mount technology (SMT), the quality of solder paste is of great significance and can directly affect the entire processSMTThe quality of the patch, high-quality solder can lead to high-quality soldering. Below, JJY solder Paste Manufacturer will give you a brief introduction to the impactSMTThe main factors affecting the quality of solder paste in surface mount technology (SMT)1Viscosity is an important factor in the performance of solder paste. If the viscosity is too high, the solder paste is not easy to pass through the openings of the template. If the viscosity is too low, it is prone to flow and edge collapse.2Adhesive solder......

NowadaysLEDMost of the electronics industry uses solder paste for soldering and packaging.LEDA chip isLEDThe key to the electronics industry. What requirements does it have for the solder paste used? Are the operations different? Now, JJY solder Paste Manufacturer will explain it:LEDChips are generally of fine-pitch or high-power type, which requires the solder paste powder used to have small particles, relatively low viscosity, high activity, and good thixotropy, effectively providing the thermal conductivity required for relatively small devices. At the same time, it is also required to have......

inPCBADuring the processing, some undesirable phenomena may occur after the circuit board is soldered, such as voids (also often referred to as air holes or bubbles).VoidThe most common defective phenomena such as (), which will directly affect the product quality. Therefore, in the daily processing, the causes should be analyzed specifically and the problems solved. Below, JJY Solder Paste Manufacturer has sorted out the main reasons for the formation of voids in solder joints, hoping to help everyone solve the problem. The main cause of voids at solder joints......

inSMTThere are some preparatory works that must be done before printing; otherwise, it will affect the printing and soldering effect of lead-free solder paste. So, what are the matters that need attention?Now, JJY solder Paste Manufacturer will explain it:1After taking the solder paste out of the refrigerator, pay attention to the expiration date of the solder paste. If it has expired, it cannot be used and should be scrapped. When taking solder paste, the principle of "first in, first out" should be followed. If there is any solder paste that has been opened before but not used up, it should be used first.2Lead-free welding......
