High-density interconnect HDI PCB represents one of the fastest-growing segments of the printed circuit board market. Due to the higher circuit density of HDI Circuit Boards, thinner lines and spaces, smaller through holes and capture pads, and higher connection pad density can be incorporated into the design. HDI PCBs have blind vias and buried vias, and usually contain microvias with a diameter of 0.006 or less. So, what are the main applications of HDI circuit boards?
1. The main advantages of HDI PCB
The development of HDI PCB technology has brought unprecedented design freedom and flexibility to engineers, allowing more components to be placed on both sides of the original PCB as needed while allowing smaller components to be placed together. This means that HDI PCB will eventually lead to faster signal transmission and enhanced signal quality.
HDI PCB is widely used to reduce the weight and overall size of products, and to enhance the electrical performance of equipment; it often appears in mobile phones, touch screen devices, notebook computers, digital cameras, and 4G network communications. HDI PCB is also prominent in medical equipment and various electronic aircraft parts.
2. Application of HDI PCB Board
HDI PCB is suitable for various industries. As mentioned above, you will find them in all types of digital devices such as smartphones and tablets, and miniaturization is the key to the effective application of products. You can also find it in cars, airplanes, and other vehicles that rely on electronics.
One of the most critical areas where high-density PCBs have made great progress is the medical field. Medical equipment often requires small packages with high transmission rates, which only HDI PCB can provide. For example, implants need to be small enough to fit the human body, but any electronic devices involved in the implant absolutely must effectively allow high-speed signal transmission. In addition, other medical equipments, such as emergency room monitors, CT scans, etc. are also available to HDI PCB.
