The much-increased packing density is the most prevalent rationale for employing HDI technology. As a result, components and their landing surfaces have access to the area created by more acceptable track constructions. Furthermore, the overall area demand lowers, resulting in a lower board size and fewer layers required.

FPGAs and BGAs with a pitch of 1mm or less are frequently available. When tracks are routed between the pins, HDI technology makes it simple to route and join. Here are the things that you will need to know.

Countless benefits such as fast speed, compact size, and high frequency are linked with HDI PCBs. The main components are mobile computers, PCs, and mobile phones. Moreover, in various user end devices, e.g., MP3 players and gaming consoles, HDI PCBs are widely employed.

HDI PCBs use the latest technologies to enhance the functionality of circuit boards via the same or small area quantity. The evolution of board technology is driven by the narrowness of components and semiconductor packages that provide superior features for inventive new goods like tactile screen tabs.

HDI-Printed Circuit Boards 

A circuit board has a diameter of 0.15mm (6 mils) to 0.1mm (4 mils) and can be drilled physically or by laser (standard). The circuit board pad has a diameter of only 0.3mm (12mil) due to a thin annular ring of only 0.1mm, which saves a lot of space compared to traditional Via pads.


Use of the Advanced Circuits

Advanced Circuits is at the front of innovation, meeting the most stringent standards with HDI PCB designs that push the boundaries of technology.

Because of technological breakthroughs and the numerous advantages, HDI PCBs provide for high-tech applications, demand for HDI PCB production has been growing. However, many PCB makers cannot fit more technology into less area with fewer layers because they lack the specialized equipment and capacity for more delicate lines, advanced features, as well as tighter tolerances. HDI Printed Circuit Board designs combine sophisticated features such as circuit boards, via-in-pad, blind vias, stacked and staggered vias, and via-in-pad with staggered and stacked vias to maximize board area while boosting performance as well as functionality.

Perfect Competencies

With in-house laser drill competencies that include precise depth control, Advanced Circuits achieves excellent quality and precision. In addition, all multilayer with inner cores is thoroughly inspected utilizing (AOI) Automated Optical Inspection units for exceptional fault identification of the most delicate details and direct laser imaging (LDI) capabilities for perfect registration.

When prototyping, there are many different types of PCBs to choose from, ranging from simple one-sided PCBs to more sophisticated multilayer boards. Copper tracks, or linkages between components on only one of the circuit board’s surfaces, are the most basic prototype printed circuit boards. Single-sided boards, or single-layer PCBs, are the name for these boards.

Quick Turn PCB Prototypes


HDI PCBs, on the other hand, are required in the production of increasingly complex boards. These printed circuit boards, also known as High-Density Interconnect, contain a higher wiring density than standard PCBs. These boards have several advantages over traditional prototype circuit boards, including narrower gaps, fewer vias, and a higher connection pad density.
