PCB design elements affecting SMT manufacturing
SMT manufacturing units are fully automatic, high precision and high speed. As the degree of automation increases, PCB design must meet the SMT equipment requirements.
How to prevent board copying through PCB design?
Common ways to prevent PCB copying board: 1, grinding, 2, sealing glue, 3, use special encryption chip, 4, the use of uncracking chip, 5, use MASK IC, 6, the use of nude, 7, in the current of the signal line series more than 60 ohms of resistance, 8, use
How to protect multilayer PCB edge radiation by PCB design?
Protection measures of multilayer PCB edge radiation: The three elements of EMC problems are: electromagnetic interference source, coupling path, sensitive equipment
The problems that should be paid attention to in PCB design are discussed from welding point of view
When designing the PCB, please note the following points: The shape of a and Mark point is symmetrical up and down or symmetrical left and right, and the size of b and A is 2.0mm. c, from the outer edge of Mark point 2.0mm, there should be no shape and co
From the drawing board point of view of PCB design four suggestions
Four suggestions for PCB design: 1, about positioning hole, 2, about MARK point, 3, about 5mm edge, 4, do not directly on the pad over the hole,
How to optimize circuit board design
With the popularity of SMT lead-free process technology, the demand for PCB substrate is getting higher and higher. The performance of PCB can be improved from the design of PCB.
Introduction to PCB design of power supply circuit
Why do you want to talk about the schematic principle in detail, because the schematic diagram contains a lot of information to draw PCB, such as the access point of the element pin, the current size of the node network, etc., see clearly the schematic di
The effect of PCBA design defect on manufacturability
The design defects of PCBA are difficult or even impossible to solve in the production process. The negligence of PCB design quality control will lead to the waste of components, materials and working hours, and even cause heavy losses.
Multi-person online collaborative PCB design
The load on the server is lighter than that on the client and therefore does not affect system performance. Tests on this environment show that the server is very responsive and does not slow down the client.
How to design pcb window opening
introduces how to realize the PCB wire window on tin, finally describes the PCB design how to set the steps of wire window, follow the small series together to understand.
In PCB design "ground" division and processing method
The specific use of which connection depends on the specific situation. These are the PCB design must understand the content, but also important data. How to partition in PADS is described later in this article.
