High-Density Interconnect Printed Circuit Board, or HDI-PCB-BOARD, is a type of printed circuit board (PCB) that has high-density components and interconnections. It is commonly used in applications that require small form factors, high performance, and reliability. In this article, we will provide a comprehensive guide to HDI-PCB-BOARD, examining its construction, applications, benefits, and challenges.

Construction of HDI-PCB-BOARD

HDI-PCB-BOARD is a complex type of PCB that requires careful design and construction. It typically consists of several layers of conductive traces and insulating material, with vias that connect the different layers. The vias are typically drilled using laser technology, allowing for small holes that can accommodate high-density components.

One of the key features of HDI-PCB-BOARD is the use of microvias, which are small vias that are less than 0.15mm in diameter. Microvias are critical for achieving high-density interconnects, as they allow for the connection of multiple layers of the PCB without taking up too much space. Microvias can be created using laser drilling or mechanical drilling, depending on the application requirements.

Another important feature of HDI-PCB-BOARD is the use of buried vias, which are vias that are located between the layers of the PCB. Buried vias are useful for reducing the size and complexity of the PCB, as they allow for the connection of multiple layers without requiring through-hole vias. Buried vias can be created using laser drilling or sequential lamination, which involves laminating the PCB in multiple stages with the vias already in place.
