Micro Circuits – HDI PCB

What Are HDI PCB Micro Circuits?

A high density interconnector printed circuit board (HDI PCB) is a circuit board that has a higher wiring density per unit area as opposed to conventional circuit boards. This allows for more components to fit in the total available space. HDI PCBs are useful for increasing electrical performance while reducing the weight and size of equipment.

HDI PCBs have minor vias, capture pads, finer spaces and lines, and higher connection pad density making them a better option for boards where space is a concern. HDI technology is regularly used in products like mobile phones, personal computers, MP3 players, game consoles, and more.

Benefits of HDI PCB Technology with Micro Circuits:

  • Shorter PCB manufacturing lead times and improved device performance for Flip Chip, BGA, MCM, SIP technologies and medical devices.
  • Allows utilization of technologies that require ultra thin cores, fine line geometries and alternative via technologies for enhanced thermal transfer in the case of a thermal PCB.
  • Allows utilization of the technologies that require 20um circuit geometries, 30um dielectric layers, 50um laser vias and 125um bump pitch processing.
  • Allows reducing the “time to market” equation by combining the process capabilities with a strong comprehension of high speed digital and high frequency RF PCB package requirements.
  • Increases the area for the PCB designer provider to place circuit components as the components are decreased in size and spaced much closer together. This also improves faster signal transmission and reduced signal loss.
