Double-sided red lead-free soldered board, featuring a high-saturation bright red solder mask layer combined with matte lead-free soldering process. The vivid red appearance not only facilitates quick identification of the board type in the production line and avoids the risk of mixed assembly, but also gives the terminal product a prominent visual identifier, meeting the requirements of electronic devices that need to highlight the appearance recognition. The board body is made of bend-resistant FR-4 substrate, with a 1oz thick copper layer and reinforced edge design. It focuses on "efficient production error prevention + strong scene weather resistance", suitable for portable medical detection equipment, industrial control button panels, automotive electronic auxiliary modules, intelligent toy control boards, etc. It can not only improve the sorting and assembly efficiency of the production line, but also ensure the long-term stable operation of the equipment in mobile or vibrating environments. It is a high-quality PCB solution that combines production practicality and scene adaptability.
