          In  PCBA factory , in order to prevent components from falling off or shifting during the wave soldering process, it is often necessary to use SMD adhesive to fix the components on the PCB board.  So what should you pay attention to when using  SMD Adhesive  in PCBA processing?   1)  The purchased  SMD  adhesive should be placed in a refrigerator below 5°C and stored in a low-temperature seal.  And do a good job in registration, pay attention to the production date and service life. It is also necessary to note that large quantities of incoming goods must pass inspection before they can be put into storage.     2)  After taking it out of the refrigerator during use, it should be restored to room temperature for 2 to 3 hours to allow it to equilibrate with room temperature before opening the container to prevent the SMD adhesive frost from absorbing moisture. Please pay attention to the ty...

          When the scorching summer sun b akes the earth , water parks become drea mlike   kingdoms  where people escape the heat and   unleash their joy . Behind this  ocean of happiness , a force of technology quietly shines   -  the underwater light PCB. Like a magician of light and shadow, it  uses   precise  technology and   innovat ive   design to  weave ever-changing colors and  rhythm s   into brilliant, joyful scenes throughout the water   park.   In the uniquely humid environment of water parks, the waterproof performance of underwater light PCBs is critical. To achieve reliable waterproofing, these PCBs employ a multi-layered protection design. Firstly, a layer of conformal coating is applied to the PCB surface. This transparent protective film acts like a "raincoat" for the PCB, effectively isolating it from water, moisture, and corrosive substances. Secondly, sealed...

Welding is to reliably connect all kinds of components that make up the complete machine product, and its quality is closely related to the quality of the complete machine product. The quality of each solder joint affects the stability, reliability and electrical performance of the entire machine. Do you know how to check the welding quality of PCBA manual welding?   1. Quality Requirement for Manual Welding 1) Electrical contact should be good:  Good solder joints should have reliable electrical connection performance, and  phenomena such as false soldering and  bridgin g  are  not  allowed.   2) Mechanical strength must be reliable: It is necessary to ensure that the solder joints will not fall off due to normal vibration during use.     3) Should maintain a beautiful appearance: The surface of a good solder joint should be smooth, bright, and free from sharp edges, wrinkles, bubbles, slag inclusions, and pitting. The transition from t...

          In PCBA factory, flux is an indispensable auxiliary material in the welding process. The quality of the welding effect is not only related to the quality of the welding technology, components and printed circuit boards, but also the selection of flux is very important. Do you know how to choose flux?   1. Performance requirements for flux 1) The flux need to have the characteristics of removing surface oxides, preventing re-oxidation and reducing surface tension, which is the basic performance that the flux must have.     2)  The melting point should be lower than the solder.   Before the solder melts, the flux must melt first to fully exert its fluxing effect.     3) The wetting and diffusion speed of flux is faster than that of molten solder.     4 ) The viscosity and density of flux are smaller than that of solder. A high viscosity will make wetting and diffusion difficult, and a high density will no...

          As the wave of intelligent transformation sweeps across the global automotive industry, artificial intelligence technology is rapidly expanding its footprint in vehicles. At the core of intelligent automotive electronic systems, AI PCBs play a vital role. They integrate high-performance computing units, sensor interfaces, power management, and high-speed communication modules, forming a solid hardware foundation for autonomous driving, smart cockpits, vehicle-to-everything (V2X) connectivity, and intelligent maintenance.     1. Autonomous Driving Systems Autonomous driving is one of the most representative applications of AI in the automotive field. Artificial intelligence PCBs integrate AI processors (such as GPUs and NPUs) and high-speed data buses to rapidly process and fuse data from cameras, millimeter-wave radar, LiDAR, and other sensors. Leveraging deep learning algorithms, AI PCBs can recognize lanes, traffic signs, pedestrians, ...
