Scientific and complete quotation requires you to provide complete information, but under special circumstances, you do not provide any information in advance, we can also give you a reference quotation. According to the above data, according to the current methods in the industry, we mainly consider the design density, circuit characteristics, complexity, design requirements and workload of the veneer in accordance with the number of pins of the veneer. If you need fast service, you need to add a certain fee. Our quotation is fixed except that the data provided at the time of quotation is not perfect or that the delivery time is greatly prolonged due to major engineering changes.
PCB design and sheeting, we use scanning technology combined with software technology, clone single, multi-level PCB, all kinds of blind buried hole PCB with high difficulty. Whether it's the computer motherboard, high-end graphics card board, gigabit network equipment baseboard with dense components, all over microstrip lines and contours, or the wireless communication equipment such as PHS motherboard, mobile phone motherboard and wireless network card with strict impedance control, which requires high-frequency processing, as well as the layers up to 30 layers, and the blind hole is buried tightly. Cloth industrial control motherboard, we can provide a complete set of samples (or prototypes) according to customers one-time cloning success.
We have been engaged in technology development and PCB design for many years. We can provide PCB board, PCB design, PCB alteration, schematic design, PCB LAYOUT, BOM table making, prototype making (including debugging), batch processing of finished products and technology according to customers'needs. Support, PCB production quality assurance and other services, to save you the cost of proofing and debugging and development, while assisting in the purchase of cold deflection gate components, compatible functional device replacement, signal source design, test stand, etc.
Several large components on the same board should have a certain distance, and in the direction of 45 angles, smaller integrated circuits such as SOP should be arranged along the axis, and resistor-capacitor components should be arranged vertically and axially, all of which are relative to the transmission direction of PCB production process. In this way, the components are arranged regularly so as to reduce the defects produced during welding. Light-emitting diodes for display should be placed at the edge of PCB because they are used for observation in the application process. Some switches, trimming elements and so on should be placed in an easy place to operate. Distribution parameters between components should be considered in the same-frequency circuit. Distribution parameters between components should be considered in general high-frequency circuit. General circuit should arrange components in parallel as far as possible, which is not only beautiful, but also easy to assemble and weld, and also easy to produce in batches. Components located at the edge of circuit board must be 3-3 from the edge. The distance is 5 centimeters. The thermal expansion coefficient, thermal conductivity, heat resistance and bending strength of PCB board should be considered comprehensively when considering the position of components, so as to avoid adverse effects on components or PCB in production.
Multi-Layer Boards (MLB) use more single-sided or double-sided wiring boards in order to increase the wiring area. Printed circuit boards with one double-sided as inner layer, two single-sided as outer layer or two double-sided as inner layer and two single-sided as outer layer, which alternate through positioning system and insulation bonding materials and interconnect conductive graphics according to design requirements, become four-layer and six-layer printed circuit boards, also known as multi-layer printing. A circuit board. The number of layers does not mean that there are several separate layers of wiring. In special cases, empty layers are added to control the thickness of the board. Usually, the number of layers is even and contains the outermost two layers. Most of the motherboards are 4 to 8 layers, but technically, they can achieve nearly 100 layers of PCB boards. Most large supercomputers use fairly multi-tier motherboards, but because such computers can be replaced by clusters of many ordinary computers, super-multi-tier boards have gradually become unused. Because the layers of PCB are closely integrated, it is not easy to see the actual number, but if you look at the motherboard carefully, you can still see it.
