1. HDI PCB Product Details:
HDI (High Density Interconnector) PCB is a relatively high line density printed circuit board using micro-blind and hidden technologies. The HDI PCB has an inner layer circuit and an outer layer circuit, and then uses drilling, through-hole plating and other processes to realize the internal connection of each circuit layer.
HDI PCB is usually produced by lamination method, the more lamination times, the higher the technical quality of HDI PCB. Ordinary HDI PCB is mainly one-time assembly, high-tech HDI PCB uses two or more assembly technologies, and adopts advanced HDI PCB technologies such as stacking, electroplating and direct laser drilling.
When the density of HDI PCB exceeds eight-layer board, the production cost of HDI PCB will be lower than the traditional and complex lamination process. HDI PCB promotes the use of advanced packaging technology, and its electrical performance and signal accuracy are higher than traditional PCBs. In addition, HDI PCB has the best improvements for high frequency interference, electromagnetic wave interference, electrostatic discharge, thermal conductivity, etc.
Electronic products are constantly developing towards high density and high precision. The so-called "high" not only improves the performance of the machine, but also reduces the size of the machine. High Density Integration (HDI) technology enables greater miniaturization of end product design while meeting higher standards of performance and electronics efficiency. At present, many popular electronic products such as mobile phones, digital (photo) cameras, laptops, automotive electronics, etc. use HDI PCB . With the update of electronic products and market demand, HDI PCB development will be very fast.
2.HDI PCB Structure Diagram:
HDI PCB is a high-density interconnect printed circuit board. Boards covered with blind holes and then recast are HDI printed circuit boards. It is divided into first order, second order, third order, fourth order and fifth order plates. Order HDI board. For example, the iPhone 6 motherboard is a 5th order HDI board .
The HDI board has 10 layers and 8 layers, and the dense peripheral layers are like a web. The internal structure of the HDI board uses 3D graphics to display the internal structure of the board circuit of various laminated structures.

7.FREQUENTLY ASKED QUESTIONS:
Q1: What are the board requirements for HDI PCB production?
A1: We are a professional HDI PCB manufacturer. We have many years of experience in PCB manufacturing. We check the quality of incoming materials layer by layer to ensure product quality. We have long-term cooperative brand suppliers such as Shengyi, Lianmao, Taiyao, Rogers.... The production process strictly controls each process and complies with international PCB quality system standards.
Q2: Can you specify the materials for PCB manufacturing?
A2: Yes, we have long-term cooperation with many copper coated laminate suppliers, and we can contact the materials you are looking for.
Q3: What is the wrong hole in the HDI board ? Why break?
A3: It means that the two layers of mechanical holes are misaligned. Because the copper plating is not done, the inside of the hole is empty, so it is not possible to drill a hole directly into it .
