Introduction to SMT Stencils Surface-mount technology (SMT) stencils are essential tools in the printed circuit board (PCB) assembly process. They are used to apply solder paste onto the PCB pads, ensuring precise and consistent solder paste deposition. SMT stencils come in various types, including framed, frameless, and step-up stencils, each […]
What are PCB Stencils? PCB stencils, also known as solder paste stencils or SMT Stencils, are thin metal sheets with precise cutouts that match the solder pad pattern on a printed circuit board (PCB). They are used during the surface mount technology (SMT) assembly process to apply solder paste onto […]
Introduction to Heavy copper PCB Heavy Copper PCBs, also known as thick copper PCBs, are printed circuit boards that feature copper traces thicker than the standard 1 oz (35 μm) thickness. These PCBs are designed to handle high current applications, improve thermal management, and enhance the overall reliability of electronic […]
