What is HDI PCB?
General Introduction of HDI PCB
High density interconnects (HDI) PCB, represent one of the fastest-growing technologies in PCBs. Because of its higher circuitry density than traditional circuit boards, the HDI PCB design can incorporate smaller vias and capture pads, and higher connection pad densities. HDI Boards contain blind and buried vias and often contain micro vias of 0.006 or less in diameter.By using HDI technology, designers now can place more components on both sides of the raw PCB if desired. Now as the development of via in pad and blind via technology, it allows designers to place smaller components closer together. This means faster transmission of signals and a significant reduction in signal loss and crossing delays.
HDI PCB is frequently found in mobile phones, touch-screen devices, laptop computers, digital cameras, 4G network communications, also prominently featured in medical devices.
Advantages of HDI PCB
The most common reason for using HDI technology is a significant increase in packaging density. The space obtained by finer track structures is available for components. Besides, overall space requirements are reduced will result in smaller board sizes and fewer layers.Usually FPGA or BGA are available with 1mm or less spacing. HDI technology makes routing and connection easy, especially when routing between pins.
Function improved by HDI PCB:
1.Denser trace routing
2.More stable power
3.Reduce interference inductance and capacitance effects
4.Improve signal integrity in high-speed design
Accelerate Development with HDI Printed Circuit Boards:
1.Easier to place SMD components
2.Faster routing
3.Reduce frequent relocation of components
4.More component space (also by Via-in-Pad)
