This 2-layer ultra-thin miniature PCB adopts a 0.45mm ultra-thin substrate, paired with precision fine circuitry and anti-oxidation surface finishing. Featuring compact overall dimensions and neat high-density wiring, it is suitable for the control of various small low-power stepper and DC micro motors. Perfectly fitting the narrow internal installation space of precision equipment, it serves as the core control board for small transmission, focusing and swing actuator mechanisms.
Minimalist 2-layer thin board structure: Designed with two layers of circuitry and a mere 0.45mm board thickness, it is ultra-thin and lightweight for internal assembly of compact mini electronic products.
Precision fine circuit fabrication: Minimum trace width and spacing of 5mil, minimum hole diameter of 0.4mm, and high-density wiring to accommodate multi-channel control signal traces for micro motors.
22μm thickened copper foil: Sufficient copper thickness delivers stable current carrying capacity, matching the continuous operating current of PCBs and reducing heat loss on circuits.
Anti-oxidation film surface treatment: Bare copper areas are protected against oxidation with excellent solder wettability. The board resists rust and oxidation during long-term service to extend product service life.
Blue solder mask process: Blue solder mask ink delivers highly legible silkscreen characters and a smooth board surface. Individual small boards maintain outstanding consistency after batch depaneling.
Panelized mass production design: Standard matrix panel layout integrates multiple independent miniature PCBs on a single substrate, boosting production efficiency and cutting unit manufacturing costs.
Office automation equipment: Micro stepper motor drives for paper feeding, photosensitive drums and lens focusing in printers, copiers and label printers.
Optical imaging equipment: Control boards for micro motors used in camera lens anti-shake and focusing, surveillance PTZ cameras, and projector auto-focus systems.
Smart home small appliances: Built-in driver boards for robot vacuum cleaners, oscillating fans, electric toothbrushes and compact food blenders.
Automotive miniature actuators: Driver boards for rearview mirror folding motors, vehicle camera focusing and air outlet wind deflection control.
3C digital products and miniature industrial equipment: Drone gimbals, handheld stabilizers, 3D printer transmission assemblies, and vibration motors for smart wearables.
