In today's electronic product market, the development of various common electronic devices in life towards miniaturization and precision is an unstoppable trend. inSMTThe quality of solder joints in surface mount technology (SMT) processing can have a significant impact. Therefore, in order to ensure quality, many tests will definitely be carried out. Now, JJY solder Paste Manufacturer will tell you about it: 1. Solder pasteSMTQuality inspection of solder joints after surface mount processing:1The surface gloss of the weld points must meet the production requirements and there should be no defect phenomena.2Component......

With the emergence and development of microelectronic products, the requirements for circuit boards of electronic products are becoming increasingly precise. inSMTDuring the surface mount technology (SMT) process, the components stand sideways after reflow soldering(It is usually a resistance-capacitance component)It is called setting up a monument. JJY solder Paste Manufacturer will share with you the reasons for setting up a monument and the corresponding solutions:1.PCBDesign reasons1,PCBThe design of the pad size is irregular. For instance, the pad design area is usually too large on the side connected to the ground wire, resulting in uneven heat capacity at both ends of the pad......

SometimesSMTTin beads will be produced during processing, which is a sign of poor processing. Generally, such plates cannot pass the appearance quality inspection. It should be of high qualitySMTAll these quality issues need to be addressed. Before solving them, we must first know the reasons for their occurrence. Below, JJY Solder Paste Manufacturer will give you a brief analysis of the reasons for the appearance of solder beads:One: Solder paste1The metal content is generally atSMTThe metal content in solder paste during surface mount technology (SMT) processing and its quality......

SometimesSMTIn surface mount technology (SMT) processing, there is an annoying poor processing phenomenon, which is false soldering. The manifestation of false soldering is generally on the surfaceSMTSurface mount components are soldered to the pads, but in reality, they are not perfectly integrated. After going through various complex processing techniques in electronic processing, a kind of poor soldering phenomenon is very likely to occur. There are generally two specific reasons for the formation of false soldering. One is thatSMTDuring the processing, due to improper processing and production techniques......

inSMTSolder paste printing is a crucial processing step in surface mount technology (SMT) processing, and it plays a significant role inSMTThe processing is a relatively early production process and also a place prone to poor processing. Many poor problems in surface mount technology (SMT) processing are caused by errors in solder paste printing. Now, JJY Solder Paste Manufacturer will introduce to you the problems in solder paste printing:1. Causes of sharpening: It might be due to gaps in the scraper or excessive viscosity of the solder paste. Avoid or solve......
