Microvias are implemented in high-density interconnect (HDI) layers, printed circuit boards with a higher wiring density than traditional PCBs in Flexible PCB manufacturer. Per a study published by MIT, an HDI is made of a number of layers of conducting materials, consisting of the signal, power, and ground connections, which are then separated by dielectric material, glued together by an adhesive, and linked together by microvias. Leveraging HDI microvias boasts a vast array of benefits to those using them, including:

•Compactness – HDI PCBs have a much higher wiring capacity, making them the best option available for a small circuit board boasting tremendous output. HDI PCBs can dramatically lower the number of layers needed to function. For products that rely on small design constraints, these printed circuit boards are a necessity.

•Higher Heat Resistance – Because HDI microvias are made using the smallest holes possible with laser drill technology, the board as a whole has higher heat resistance.

•Faster Signal Transmission – HDI PCBs use space with much greater efficiency than their counterparts, meaning more circuitry can be placed on a single surface. With less distance to travel, electrical signals lead to increased performance and functionality by producing additional input and output, resulting a sharp decline in signal loss and crossing delays.

•Quicker Prototyping – HDI design in Flexible PCB manufacturer diminishes the time and money put into designing and implementing prototypes. With shorter lead times, profit margins increase in turn.

•Lower Materials Cost – HDI PCBs use significantly less material than comparable circuit boards for increased performance power. This efficiency directly translates into less materials used during the production process, allowing you to generate higher volumes of revenue.

In short, HDI printed circuit boards have better performance, are more cost effective, and lead to higher volumes of revenue over time. With a smaller design, these circuit boards allow for a larger variety of applications across the board, from aeronautics to consumer products.


Microvias solve a major problem in printed circuit board design: accommodating as much as possible into a limited amount of “real estate” on layers of a printed circuit board. In the process, microvias have not only allowed for the functionality of a computer to fit in our pockets, but has led to decreased costs for consumers as well as greater reliability and efficiency for the products themselves.

Every year, printed circuit boards grow smaller and smaller while engineers work to make them perform at higher clock rates. PCB fabrication houses must contend with the challenges that come with miniaturization standards that change on a yearly basis. For this reason, finding a reliable fabrication partner has never been more important than now.
