Blind Buried Circuit Board: Definition Noun Interpretation
When it comes to blind buried hole circuit boards, everyone's understanding and understanding of blind buried hole circuit boards are vague. Some manufacturers cannot know exactly what a blind hole is, how to treat a blind hole and what kind of blind hole it is. Plate, what is a buried orifice plate, the definition and difference of buried orifice plate; let us talk about the history of PCB board: the name of the circuit board appeared from the 20th century to the beginning of the 21st century, the emergence of circuit boards has led to the development of electronic products. Technological progress has advanced by leaps and bounds, and electronic assembly technology has been rapidly improved. However, due to the increase in circuit density, the packaging method of parts is constantly updated. In order to allow the limited circuit board area to place more high-performance parts, in addition to the thinner circuit width, the diameter of the hole has been reduced from 1 mm in the DIP jack to 0.6mm in the SMD, and further reduced. to less than 0.4mm. But it still occupies surface area, so there will be buried holes and blind holes. The definition of the blind buried hole circuit board is as follows:
buried hole
buried hole is the through hole between the inner layers. They cannot be seen after pressing, so there is no need to occupy the outer area. The upper and lower sides of the holes are located in the inner layer of the plate, in other words, they are buried inside the plate. In short, it's just caught in the middle, you can't see these processes from the surface. Therefore, before the production of buried hole circuit boards, you must carefully ask and understand the documents, otherwise it will bring a lot of trouble!
blind hole
blind buried hole circuit board is used to connect the surface layer and one or more inner layers. One side of the hole is on the side of the plate, and then reaches the inside of the plate. Simply put, the surface of the blind hole can be seen on one side and the other. The board is invisible, just like the orderlies in our daily lives. There is only one opening on the surface, and the water leads to the ground. If you want to make samples, it is recommended that you go to Jaguar 24 Hours Fast PCB Factory to try it out. PCB proofing is priced online, with fast response, affordable price, fast speed and good quality. Through the above introduction, I hope you have an understanding of blind holes. Be understanding.

Most electronic products are inseparable from the component is multilayer circuit board, and the production quality of multilayer circuit board factory directly determines the use of electronic equipment and the use of quality, there are many points in the circuit board processing related to the compatibility of multilayer circuit board, and then affect the quality of the circuit board. What are the main points of the compatibility design of multilayer circuit boards under the popular science?_multilayer circuit board_multilayer circuit board factory_blind buried hole circuit board_HDI board proofing

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.
