Black Multilayer Board HDI PCB BGA Package PCB Manufacturing Service

♦ What is HDI PCB?

HDI PCB uses micro blind/buried vias and build-up technology to create high-density circuits. It forms micron-level interlayer connections via laser drilling and electrochemical plating, eliminating reliance on traditional through-holes. Basic versions have single-layer structures, while advanced variants stack multiple layers with technologies like stacked vias and laser direct imaging to boost density and performance.

♦ Characteristics of HDI PCB

• • High line density: More components and connections can be accommodated on a smaller board area, providing greater flexibility for circuit design.

  • New packaging technology: Using smaller and denser component packaging such as micro BGA to achieve more compact design and optimize the size and performance of electronic equipment.

  • Excellent multi-layer structure: Through multi-layer superimposed blind and buried via structures, the size of the circuit board is reduced, the performance is improved, and a higher degree of integration is achieved.

  • Good signal integrity: Shorter signal transmission paths and smaller component connections provide better signal integrity and reduce signal loss and interference.

♦ Applications of HDI PCB

• • Medical field: used in pacemakers, CT scanners, medical imaging equipment, etc., to meet the requirements of equipment miniaturization, high performance and high reliability. For example, the utilization rate of HDI PCB in high-end medical equipment exceeds 70%.

  • Aerospace: used in aircraft avionics systems, satellite communications, navigation systems, etc., to meet the high performance and high reliability requirements of equipment in extreme environments. For example, the aircraft autopilot system uses HDI PCB to ensure flight safety.

  • Industrial control: used in programmable logic controllers (PLCs), industrial robot control systems, etc., to adapt to complex industrial environments and ensure precise control of industrial production.
