PCB Cabling 6 Major principles1 power, ground processing not only in the entire PCB board in the wiring is done well, but due to the power, grounding the consideration of the interference caused by, will make the performance of the product decline, and sometimes even affect the success rate of the product. Therefore, the wiring of electricity, grounding wire to be taken seriously, the electricity, ground no

, when the clock frequency exceeds 100 MHz or the rising edge is less than 1 ns, the signal integrity effect becomes important. In PCB, the signal line is the main carrier for signal transmission. The cabling of the signal line directly determines the superior signal transmission, thus directly affecting the performance of the entire embedded system. Unreasonable wiring will seriously lead to various signal integrity problems, and generate timing, noi

TheseGuidelines will help to minimize signal quality and EMI problems. The high speed USB validation effortsFocused on a four-layer motherboard where the first layer is a signal layer, the second layer is power,Third layer is ground and the fourth is a signal layer. This results in placing mos

During circuit design, there are more and more power supplies and multiple locations on a PCB, such as 48 V, 12 V-Common types of power supplies such as 12 V, 5 V,-5 V, 3.3 V, 2.5 V, 1.8v1.v, agnd (analog location) dgnd (Digital location), pgnd (Protected Area) the ground plane required for different functions, some IC clearly requires the single point grounding, and the required power supply, ground plane hollowing. In order to ensure high reliabilit

When drawing a PCB, you often need to check the corresponding components on the schematic. If the number of components is small, you can find them. Also, alicloud designer provides a good cross-search function. Here I suggest using two monitors, one with a schematic diagram and the other with a PCB, which makes it easier to find out. 1 use the shortcut key T + c This shortcut key is used in both the schem

After "one-click Restore wizard" is uninstalled, how does one Delete the G. Folder backed up by the wizard? After "one-click Restore wizard" is installed, a backup folder yjbf is created automatically in the last hard disk partition (different versions may also be in other partitions of the non-C disk), which contains the file G ., after uninstalling the "one-

Introduction to Data Recovery Wizard The Data Recovery Wizard is a powerful, easy-to-use data recovery software. The data recovery process is completed in 5 steps, and the user base is mainly for ordinary computer users. Common features are: Recover deleted files, restore formatted files, and recover lost partitions. Supported storage media are mainly computer hard disk, mobile hard disk, U disk, SD card,

Formula for propagation delay of cabling in PCB The first half is information from altera. The propagation latency (tPD) is the time required to transmit a signal from one point to another. Transmission Line propagation delay is a function of the relative dielectric constant of materials. Propagation delay of micro-Strip Layout You can use formula 5 to calculate the propagation delay of the strip layout. Formula 5: Delayed propagation in the line

Note: belong to reprint Many people for the PCB traces of the reference plane is confused, often asked: for the inner layer traces, if the line side is VCC, the other side is GND, then which is the reference plane? To figure this out, you have to understand the concept of transmission lines. We know that the transmission line must be used to analyze the signal transmission on the PCB in order to explain th

transistors and variable resistors, their packaging is the most headache, the same packaging, its pin is not necessarily the same. For example, for packaging such as to-92b, usually 1 feet is e (emitter), and 2 feet may be B-pole (base), or C (collector), the same, 3 feet may be C, also may be B, specifically that, only to get the components can be determined. Therefore, the circuit software is not hard to define the name of the pad (pin name), the same, FET, MOS tube can also be used in the sa

A process is a dynamic description of a program, which is the smallest unit of the operating system's resource allocation (the thread is the smallest unit of the operating system execution entity). for a multi-channel program system, there may be many processes in memory, in order to facilitate the management of these processes, the operating system kernel for each created process to establish a structure to save its related information. This structure is the

High Frequency Circuit Wiring techniques in PCB Layout 1. Multi-board wiring High-frequency circuits often have a high degree of integration and a high wiring density. Using a multi-layer board is not only required for wiring, but also an effective means to reduce interference. In the PCB Layout stage, a proper selection of printing board sizes of a certain number of layers can make full use of the middle
