PCB Optimization Design (II.)2011-04-25 11:41:05| Category: PCB design SMT technology is now very mature and widely used in electronic products, therefore, electronic product designers need to understand the SMT technology common Sense and manufacturability design (DFM) requ

PCBDesign Process Reprinted from: http://www.pcbhz.com/html/Services/pcbsj/pcblc/ First, make preparations. This includes preparing the component library and schematic. In progress PCB Before design, prepare the schematic diagram. SCH Component Library and PCB Component Library. Component Library can be used Peotel It is difficult to find a suitable li

In this article, we will discuss the PCB cabling design methods and requirements. The layout design of components and the direction of electrical connections may produce different results, and the results may vary greatly, therefore, the structure of printed circuit board components should be correctly designed and the correct

Author: Instructor Lu,Hua Qing vision embedded college lecturer. 4. Brief PCB design To compile the schematic diagram or the entire project, this step is to generate a network table and prepare for the work. Open it in project and project options. 4.1 DRC rules In terms of electrical rules, I searched for some annotations on the Internet for reference:Violations associated with buses various types of bus el

Although semiconductor integration is becoming increasingly high, many applications also have ready-to-use on-chip systems, while many powerful and out-of-the-box boards are becoming more accessible, but many use cases of electronic products still require the use of custom PCBs. In one-off development, even a common PCB can play a very important role. The PCB is the physical platform for the

Despite the increasing integration of semiconductors, many applications also have ready-to-use on-chip systems. At the same time, many powerful and out-of-the-box development boards are increasingly accessible, however, in many use cases, the application of electronic products still needs to use custom PCB. In one-time development, even a general PCB can play a very important role.

verify Sometimes, the network relationship of the painted board is different from that of the schematic diagram due to misoperations or negligence. In this case, it is necessary to check the network. Therefore, after the painting, you cannot rush to hand it over to the plate manufacturer. You should first check it before proceeding with the subsequent work. How Should PCB design and mechanism

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

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

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
