Traditional PCBs consist of multiple layers of copper traces and vias interconnected by drilled holes. However, the limitations of traditional PCBs, such as increasing miniaturization demands and restricted routing space, led to the development of HDI PCBs. To discover additional and complementary information on the subject covered, we’re committed to providing a rich educational experience. high density interconnect!

The Basics of HDI PCBs

HDI PCBs are characterized by their high-density component mounting and intricate interconnections. Unlike traditional PCBs, which rely on through-hole technology, HDI PCBs utilize microvias to connect the layers of the board. Microvias are smaller in diameter and can be placed much closer together, allowing for a higher density of components and traces.

HDI PCBs can be classified into several types, including 1+N+1, 2+N+2, and sequential buildup. The number before the “+” symbol represents the number of layers with microvias and the number after the “+” symbol indicates the number of layers without microvias. Each type of HDI PCB offers different design possibilities and capabilities for various applications.

Benefits of HDI PCBs

There are several advantages to using HDI PCBs in electronic devices:

  • Increased Component Density: HDI PCBs allow for more components to be packed into a smaller space, making them ideal for compact electronic devices and wearables.
  • Better Signal Integrity: The shorter microvias used in HDI PCBs result in shorter signal paths, reducing the risk of signal interference and improving overall signal integrity.
  • Improved Thermal Performance: By reducing the size and number of vias, HDI PCBs enhance the thermal conductivity of the board, leading to better heat dissipation and increased reliability.
  • Enhanced Electrical Performance: HDI PCBs offer lower inductance and capacitance, improving the electrical performance of high-speed circuits and reducing signal loss.
