These two PCBs with a PCB size of less than 1mm are high-precision and difficult electronic manufacturing products with unique challenges and advantages. First of all, the manufacture of such circuit boards involves extremely high technical requirements and precision processing technology. In addition, due to the lack of positioning holes, problems such as board edge bumps, PCB being sucked away due to dust suction, and uncontrollable shape tolerances are prone to occur when processing using external positioning methods. Despite these challenges, the application prospects of ultra-small size circuit boards are broad.
They are widely used in portable devices, medical devices, military equipment and other fields, and can provide higher integration and smaller device profiles, thereby meeting the needs of modern electronic products for light, short, and high performance, and bringing more possibilities for the development of electronic products.
