Another common problem with EMI generation when PCB wiring is changing the reference plane layer without specifying a closed physical path for the signal PCB routing of the return current.
the traditional physical plate making method is labor-intensive, time-consuming and has low precision, while the chemical rapid plate making method has a controllable precision, but the process is complicated and unfavorable to environmental protection. B
whether considering from market demand or enterprise development, it is particularly important for PCB system design engineers to complete the design and timely delivery with low cost, fast and efficient.
It is suggested that the signal layer should adopt the positive processing mode, and the power layer and ground layer should adopt the negative processing mode, which can greatly reduce the size of the file data and improve the design speed.
the new 3D Workbench solution Bridges the gap between mechanical and electrical areas, enabling product development teams to quickly and accurately analyze signals across multiple boards.
Next, I will introduce the research and development process of PCBA products.1. Market research; 2. Prototype and interaction design; 3. Hardware development - main chip confirmation
How to consider the welding process in PCB design? 1. Power line and ground wire should meet the following requirements in PCB design: (1) The power line and ground wire of large area should be drawn into a cross section line; (2) The distribution of copp
The basic working conditions of PCBA patch after processing are as follows: 1. Working conditions: Temperature: 18℃ to 28℃, humidity: 35% ~ 75%; 2. 2. Operation object: all PCbas; 3. Operator: with certain general SMT and DIP welding status identification
Special care should be taken to choose the form and position of segmentation, that is, to make the two better isolation, and do not hinder the flow of driving current and circuit current, with inductance or magnetic bead connection is able to isolate the
As an important part of PCBA, SMT processing has a direct impact on product quality. SMT processing includes multiple processes. How to standardize each process so as to post perfect PCBA
As the complexity of electronic circuits continues to increase, new technologies raise the bar for these products.
Teach you how to choose quality pcb manufacturers:First, look at the product, two, see the application, three, listen to the voice, four, see the reputation, five, see the service
