Blind buried hole circuit board: high precision circuit board explanation
With the development of electronic products to high density and high precision, the same requirements are also put forward for circuit boards. The most effective way to increase the density of the PCB blind hole circuit board is to reduce the number of through holes, and accurately set the blind holes and buried holes to meet this requirement, thereby forming the HDI board.
HDI blind buried hole circuit board is a compact product designed for small capacity users. It adopts modular and parallel design. One module has a capacity of 1000VA(1U height) and has been naturally cooled. It can be placed directly in a 19-inch rack, and up to 6 modules can be connected in parallel. The product uses full digital signal process control (DSP) technology and a number of A patent technology, regardless of the load power factor and crest factor, has a comprehensive adaptive load capacity and strong short-term overload capacity.
HDI blind buried circuit board is mainly manufactured using micro blind hole and buried via hole technology. It is characterized in that the electronic circuits in the printed circuit board can be distributed with higher circuit density, and because of the large increase in circuit density, the printed circuit board made of the HDI board cannot be used. Typically, for drilling, HDI must employ a non-mechanical drilling process. There are many non-mechanical drilling methods. Among them, "laser drilling" is the main hole forming solution for HDI high-density interconnection technology.
HDI blind-buried circuit boards are usually manufactured by stacking methods. The longer the setup time, the higher the technical level of the circuit board. It can reduce the cost of PCB blind hole circuit board: when the density of PCB increases to more than eight layers, it is manufactured with HDI blind hole circuit board, and its cost will be lower than the traditional complex pressing process.

In the graphic electroplating process method of multi-layer circuit board factory, because the circuit pattern is easy to produce side etching in the etching process, the tin-lead alloy plating part is in the air and produces a suspension layer, which is easy to fall off, resulting in a short circuit caused by bridging between wires. Multilayer circuit board factory uses infrared hot melt process method, can make the exposed copper surface get very good protection. However, when it is used for infrared thermal melting of multi-layer circuit boards, the phenomenon of delamination and foaming between layers of multi-layer circuit boards is very serious due to high temperature, resulting in a very low yield of multi-layer circuit boards. _Blind buried hole circuit board_multilayer circuit board

Before designing multilayer circuit boards, the multilayer circuit board structure must be determined according to the circuit scale, circuit board size and electromagnetic compatibility (EMC) requirements. That is to decide whether to use a 4-layer, 6-layer or higher multilayer circuit board. Once the number of layers is determined, the multilayer circuit board factory has decided to determine the placement of the electrical layers in the multilayer circuit board and how to distribute different signals on these layers. This is the choice of multilayer circuit board factory laminated structure.
