Introduction to HDI

HDI (High Density Interconnection): High-density interconnection technology, mainly using micro-blind vias/buried vias (blind vias/buried vias), which is a technology that makes HDI PCB circuit boards more densely distributed. Its advantage is that the PCB circuit board can be greatly increased and the product can be miniaturized as much as possible. However, due to the increase in line distribution density, it is impossible to use traditional drilling methods to drill holes. Some vias must be drilled with lasers to form blind holes, or interconnected with embedded via holes in the inner layer to complete the external layer. Laser drilling and plating, then covering the outer layer with an insulating layer (prepreg). ) and repeat the outer layer circuit fabrication, or continue laser drilling, stacking outward one layer at a time.

Usually, the diameter of the laser drilled holes is designed to be 3~4 mils (about 0.076~0.1mm), and the insulation thickness between each laser drilled layer is about 3 mils. Since laser drilling is used many times, the key to the quality of HDI circuit boards is the hole pattern after laser drilling, and whether the holes can be uniformly filled after subsequent plating and filling.

Below are examples of HDI PCB board types. The pink holes in the picture are blind holes, laser drilled and typically 3 to 4 mils in diameter; the yellow holes are buried holes formed by mechanical drilling and are at least 6 mils (0.15mm) in diameter.

Medical equipment

Electronics make a major contribution to health - the nursing industry, as diagnostic, monitoring and therapeutic equipment. As the development of electronics becomes more efficient and dense, the medical applications of these electronic devices continue to grow, leading to endless new possibilities.At the heart of these medical devices is the HDI PCB. PCBs in the medical industry are highly specialized to accommodate the unique constraints of medical devices. In many medical applications, small packages are required to meet the size requirements for implants or emergency room monitors. Therefore, medical PCBs tend to be specialty high-density interconnect PCBs, also known as HDI PCBs. Medical PCBs can also be made with flexible substrates that allow the HDI PCB to bend during use, which is essential for both internal and external medical devices.

1. Monitors: Personal and healthcare monitors, including blood glucose monitors, heart rate and blood pressure monitors, and more.
2. Scanning Technology: CT scanners and ultrasound technology typically use PCB-based electronics.
3. Control System: The device controls the infusion, flow rate and distribution are electronically controlled.
4. Internal Devices: Pacemakers and similar internal medical devices keep patients healthy and are operated by a central micro-PCB.
