ObjectiveThe last two days using AD14 software designed a Bluetooth anti-loss circuit board (PCB) drawings, the middle of some details in this document, to facilitate the next design of the PCB reference. Also hope to give the layman's classmates or just into the students a macro view of the General circuit board design process of the article.First, install AD14, crack, account registration, plug-in downloa

After four years of graduation, although the driver of embedded real-time software systems has been working for some time, the title of "Hardware Engineer" has always been available. In fact, it is a bit embarrassing, not to mention the depth of the hardware, in addition to a considerable amount of time to design the hardware circuit, more importantly, the PCB layout. Think about the circuit board, from the single panel on the front panel of the simpl

As a PCB engineer, what should I pay attention to in lay PCB? 1. After the power supply comes in, first go to the filter capacitor. After the filter capacitor is obtained, it is sent to the following device. Because the cabling on the PCB is not an ideal wire, there is a resistor and a distribution inductance. If the power is obtained from the front of the filte

With the help of software, you can go to linux for PCB-general Linux technology-Linux programming and kernel information. The following is a detailed description.

Allegro PCB design experience 1. When components are encapsulated, what is the pin number defined for a pad without an electrical connection?Answer: when placing a pad, select Mechanical. 2. How to add tears in allegro?A: You must first open all the cabling layers and execute the command route-> gloss-> parameters .., in the displayed dialog box, click pad and T connection fillet, click the square on the left, and click circular pads, pins, vias,

Before designing a multilayer PCB, the designer must first determine the structure of the PCB based on the circuit size, circuit board size, and EMC requirements, that is, it is decided to adopt a 4-layer, 6-layer, or more layers of the circuit board. After determining the number of layers, determine the placement location of the inner electrical layer and how different signals are distributed on these laye

After the schematic design, the drawing board is required. a pcb file is required. There are several ways to generate a PCB file: 1. directly use File> New> PCB in the toolbar to create a PCB, as shown in figure 2. Another better method is to use the PCB generation wi

The thickness of most PCB copper foil is 35um (if you are not sure, you can ask the

We all know that PCB is to turn the designed schematic diagram into a real PCB Board. Please do not underestimate this process. There are many things that work in principle that are hard to implement in the project, or what others can achieve, but others cannot. Therefore, it is not difficult to do a PCB, but it is not easy to do a PCB.The two major difficulties

One, Process Control block (PCB) structureThe Process Control block (PCB) is a specialized data structure that is set up by the system in order to manage processes. It is used by the system to document the external characteristics of the process and to describe the process of its movement. At the same time, the system can use the PCB to control and manage the pro

First, the circuit design of the advance work1, draw schematic diagram with schematic design tool, and generate corresponding network table. Of course, some special cases, such as the circuit version is relatively simple, already have a network table and other circumstances can not be schematic design, directly into the PCB design system, in the PCB design system, you can directly take the part package, man

Address: http://pda.c114.net/164/a565914.html Introduction Signal integrity refers to the signal quality in the circuit system. If the signal can be sent from the source end to the receiving end without losing sight within the required time, it is called that the signal is complete. With the rapid development of semiconductor technology, the output speed of IC switches is improved, and the signal integrity problems (including signal overshoot and underloading, ringing, reflection, crosstalk, an

Before the introduction of the PCB (Process Control block), the first implementation of a ' progress bar ', and then according to the program written to analyze the specific PCB implementation principles. The ' progress bar ' function is able to be displayed in a single line, while the progress bar has a dynamic growth change, to know the ratio in the progress bar, but also need to be able toShows you know

The testability concept of PCB DesignThe testability of the product design (De sign for testability. OFT) Product manufacturability is also the main content from the production point of view is also one of the design process. It refers to the design of the product performance can be considered difficult to detect, that is, design products should consider how to use the simplest method of product performance and processing quality testing, or product d
