HDI Technology PCB Prototype
HDI PCB (High Density Interconnector PCB), HDI Technology PCB is a circuit board having a relatively high line distribution density using the micro-blind and buried hole technology.
It is a process that includes an inner layer line and an outer layer line, then uses a hole and a metallization in the hole to realize a joint function between the inner layers of each layer.
With the development of high-density, high-precision electronic products, the same requirements are imposed on circuit boards. The most effective way to increase the density of pcb is to reduce the number of through holes, and to accurately set the blind holes and buried holes to achieve this requirement, thereby generating an HDI Technology PCB.
We offer low-volume, Prototype and Production PCB fabrication service, for HDI PCB, Rigid PCB, Flexible PCB, High Tg boards, etc. All project comes with satisfaction guarantee and on-time delivery.
HDI: High Density Interconnection Technology. It is a multilayer board made by a build-up method and a micro-blind buried hole.
Micro-hole: In a PCB, a hole less than 6 mil (150 um) in diameter is called a micro-hole.
Buried Via: buried in the inner layer of the hole, not visible in the finished product, mainly used for the conduction of the inner layer line, can reduce the probability of signal interference, and keep the continuity of the characteristic impedance of the transmission line. Since the buried via does not occupy the surface area of the PCB, more components can be placed on the surface of the PCB.
Blind Via: connecting the surface layer and the inner layer without passing through the full-board via holes.
Key HDI PCB Benefits
The evolution of high-density PCB technology has given engineers greater design freedom and flexibility than ever before. Designers using HDI high density interconnect methods now can place more components on both sides of the raw PCB if desired. In essence, an HDI PCB gives designers more space to work with, while allowing them to place smaller components even closer together. This means that a high-density interconnect PCB ultimately results in faster signal transmission along with enhanced signal quality.
HDI PCB is widely used to reduce the weight and overall dimensions of products, as well as to enhance the electrical performance of the device. The high-density PCB is regularly found in mobile phones, touch-screen devices, laptop computers, digital cameras and 4G network communications. The HDI PCB is also prominently featured in medical devices, as well as various electronic aircraft parts and components. The possibilities for high-density interconnect PCB technology seem almost limitless.

Benefits of using HDI Printed Circuit Boards As consumer demands change, so must technology. By using HDI technology, designers now have the option to place more components on both sides of the raw PCB. Multiple via processes, including via in pad and blind via technology, allow designers more PCB real estate to place components that are smaller even closer together. Decreased component size and pitch allow for more I/O in smaller geometries. This means faster transmission of signals and a significant reduction in signal loss and crossing delays.
