Shenzhen well-known four-la... As a component of high-precision electronic products, PCB proofing is already a very common existence in life. However, we all know that the domestic professional PCB proofing design needs to be set at different points at different stages, and large grid points will be used for device layout in the layout stage. Let's take a look at detailed PCB proofing layout setup tips.Under normal circumstances, all small parts of PCB proofing should be arranged on the same circuit board, but in the case of too many and too dense PCB proofing parts of some good quality, chip resistors, capacitors, chip ICs and other parts with limited height and less heat generation will be placed in the lower layer. And under the premise of fully ensuring the electrical efficiency of PCB proofing, these parts should be placed on a fixed grid, so that they are parallel or perpendicular to each other to achieve a neat, beautiful effect, in short, under normal circumstances, PCB proofing parts are not allowed to overlap. The arrangement of PCB proofing parts should be compact, and its distribution should be uniform and dense on the entire layout. Since PCB proofing is a very small part, the small spacing between the pad graphics of different components on the circuit board should be very weak, and the mechanical strength that the board can withstand should be considered in the actual setting.In the layout design of PCB proofing, the unit of the circuit board should be analyzed, and the layout design should be carried out according to the function, and all the components of the circuit should be laid out in accordance with the following principles: arrange the position of each functional circuit unit according to the flow of the circuit, so that the layout is convenient for signal circulation, and the signal is as consistent as possible. Centered on the core components of each functional unit, layout around it. The original parts should be uniform, integral and compact arranged on the PCB proofing to minimize and shorten the leads and connections between the components.

PCB board batch PCB layout rules:Under normal circumstances, all components should be arranged on the same surface of the circuit board, and only when the top components are too dense, some devices with limited height and small heat generation, such as chip resistors, chip capacitors, chip ICs, etc., can be placed in the low layer.Under the premise of ensuring electrical performance, components should be placed on the grid and arranged parallel or perpendicular to each other to achieve neatness and beauty, and in general, components are not allowed to overlap: the arrangement of components should be compact, and the components should be evenly distributed and dense and consistent throughout the layout.THE SMALL SPACING BETWEEN THE PADS OF DIFFERENT COMPONENTS ON THE CIRCUIT BOARD SHOULD BE MORE THAN 1MM.THE EDGE OF THE CIRCUIT BOARD IS GENERALLY NOT LESS THAN 2MM.THE SHAPE OF THE CIRCUIT BOARD IS RECTANGULAR, AND THE ASPECT RATIO IS 3:2 OR 4:3.WHEN THE CIRCUIT BOARD SIZE IS GREATER THAN 200MM BY 150MM, THE MECHANICAL STRENGTH THAT THE CIRCUIT BOARD CAN WITHSTAND SHOULD BE CONSIDERED.Single-sided PCB board12 hours PCBkuai quick proofing, 30 minutes quotation response.■ PCB proofing price as low as 50 yuan a piece, can process PCB boards below 30 layers.■ The cost of single and double panel proofing project is reduced by 20%, and the color fee is free.■ 24-hour expert technical support, A-grade quality, AOI optical + flying probe test.PCB proofing layer range:2-30 layer PCB (rigid)PCB proofing material range:FR-4 (including high Tg, high CTE), high-frequency materials (including PTFE, PI, BT, Rogers, etc.), aluminum-based materials, tong-based materials, embedded passive component materialsPCB proofing processing characteristics range:Blind/buried plates, characteristic impedance control boards, HDI boards, thick tong boards, rigid-flex boards, high-frequency materials and FR4 mixed multilayer boards, embedded passive component boards, metal base circuit boardsPCB proofing surface treatment range:Hot air leveling, chemical gold, chemical tin, chemical silver, surface oxidation, plug gold plating, lead-free tin sprayingScope of application:Consumer electronics, communication and communication, industrial control equipment, computers and peripheral equipment, automotive electronics, yi therapy equipment, power supply

How much is the price of si... PCB proofing is a kind of circuit board printing in a small range of trial production before mass production, the main application is electronic engineers in the design of the circuit, and after the completion of the PCB, to the factory for small batch trial production process, that is, PCB proofing. And with the continuous development of China's science and technology, PCB proofing is also in continuous development, and PCB proofing with good quality and low price still has a lot of room for development in the future.Due to the continuous efforts and hard research and development of Chinese researchers for PCB proofing, China's PCB proofing has entered a highly developed era and has been widely recognized by the PCB industry around the world. The obvious manifestation is that many electronics manufacturers at home and abroad have begun to use Chinese-made PCB proofs as an integral part of their electronic products. And now China's PCB proofing is still spreading to various places, various industries, and has been used more extensively, so users do not have to worry about the future development trend of PCB proofing, because PCB proofing as a basic component has been widely used in more and more industries.At present, domestic professional PCB proofing has made significant progress in product structure. Since the 19th century, a variety of electronic products have continued to come out, computers and other electronic products have gradually become an indispensable object in people's lives, and PCB proofing is the basis of these electronic products, providing the core operating conditions for these electronic products. With the continuous development of electronic products, PCB proofing is also constantly improving. The future development of electronic products certainly does not need to be said, because electronic products are not only a necessity of modern society, but also it meets the needs of modern social development, so it must be prosperous. As the main core of electronic products, PCB proofing constitutes the original object, and it will definitely continue to develop with electronic products.At present, the PCB proofing industry should be a very considerable industry in the future development trend. Because with the continuous advancement of process technology, many industries need to use PCB proofing, and good quality PCB proofing has a market state of short supply, and we can clearly know from the above that the future PCB proofing development will definitely become increasingly prosperous.
