HDI PCB Board Introduction


HDI PCB Board, also known as high-density interconnect PCB, is a kind of PCB with a higher wiring density per unit area than traditional boards. HDI boards are more compact and have smaller vias, pads, copper traces and spaces. As a result, HDIs have denser wiring resulting in lighter weight, more compact, lower layer count PCBs. HDI PCB is more fit into the little spaces and have a smaller amount of mass than conservative PCB designs.


Haina Lean provide One-stop PCB Board Favrication and assembly service , include :SMT Assembly , BGA Assembly , HDI ,Through-Hole Assembly ,Mixed Assembly,Rigid Flex PCB Assembly services . etc.

HDI PCB Application Field


Automotive and aerospace industries, where lower weight can mean more efficient operation, have been utilizing HDI PCBs at an increasing rate. such as onboard WiFi and GPS, rearview cameras and backup sensors rely on HDI PCBs. As automotive technology continues to advance, HDI tech will likely play an increasingly important role.


HDI PCBs are also prominently featured in medical devices; advanced electronic medical devices such as equipment for monitoring, imaging, surgical procedures, laboratory analysis etc., and incorporate HDI boards. The high-density technology promotes improved performance and smaller, more cost-effective devices, potentially improving the accuracy of monitoring and medical testing.


Industrial automation requires abundant computerization, and IoT devices are becoming more common in manufacturing, warehousing, and other industrial settings. Many of these advanced equipment employ HDI technology. Today, businesses use electronic tools to keep track of inventory and monitor equipment performance. Increasingly, machinery includes smart sensors that collect usage data and connect to the internet to communicate with other smart devices, as well as to relay information to management and help optimize operations.


Except mentioned above, you'll also can find high-density interconnect PCBs in all types of digital devices, like smartphones and tablets, in automobiles, aircraft , mobile /cellular phones, touch-screen devices, laptop computers, digital cameras, 4/5G network communications, and military applications such as avionics and smart munitions.
