Brief: Join us for a close-up look at the manufacturing process of our FR4 OSP Surface Multilayer Printed Circuit Boards. In this video, you'll see how we laminate multiple conductive copper layers under high pressure and heat, explore the sophisticated assembly that enables high-density wiring, and learn about the key advantages that make these 4-layer PCBs ideal for complex, miniaturized devices. We'll also walk you through our factory showcase, quality testing procedures, and the simple steps to order your custom OEM/ODM boards.
Related Product Features:
  • Features a 4-layer FR4 construction with OSP surface finishing for reliable performance.
  • Enhances signal integrity by separating signal layers from power and ground layers.
  • Enables higher component density and space savings for compact, complex circuit designs.
  • Improves electromagnetic compatibility with dedicated power and ground layers.
  • Offers cost-effectiveness for designs where 2-layer boards are insufficient.
  • Reduces the need for external noise filters and additional components.
  • Supports custom OEM/ODM services with quick quoting and DFM analysis.
  • Accepts Gerber files, BOM, impedance requirements, and test specifications for ordering.
FAQs:
  • What are the main advantages of using a 4-layer FR4 PCB?
    The main advantages include enhanced signal integrity by separating signal and power layers, higher component density for space savings, improved electromagnetic compatibility for reduced noise, and cost-effectiveness for complex designs where 2-layer boards are insufficient.
  • What files and information do I need to provide to order a custom multilayer PCB?
    You should provide Gerber files (RS-274X), a Bill of Materials (BOM) if PCBA is needed, impedance requirements and stack-up details if available, and any specific test requirements such as TDR or network analyzer tests.
  • How does the multilayer PCB structure improve electromagnetic compatibility?
    The dedicated power and ground layers form a stable 'power-ground plane capacitor' that filters out high-frequency noise. It also isolates sensitive analog signals from noisy digital circuits on separate layers, reducing electromagnetic interference emissions and susceptibility.
