When troubleshooting non-functional or non-performing circuits, engineers can often run simulations or other analytical tools to consider the circuit at the schematic level. If these methods fail to solve the problem, even the best engineers may be stumped, frustrated, or confused. I've been through this before. To avoid this kind of cul-de-sac, here's a simple [...]
At present, there are so many PCB design software, which PCB design software should be learned? At present the mainstream of the three PCB design software, the current mainstream is not mentioned. 1. Altium Designer is short for AD. It's sort of an updated version of PROTEL. 2. PADS 3. Cadence allegro Don't worry about [...]
5G spectrum is much higher than 4G, and the number of acer stations has increased significantly 5G spectrum is much higher than 4G, with poor penetration and large attenuation of electromagnetic wave. When other factors are not taken into account, the coverage of base station is smaller than that of 4G base station, and the [...]
RF circuit board design is often described as a kind of "black art" due to many theoretical uncertainties, but this view is only partially correct, RF circuit board design also has many guidelines to follow and should not be ignored. In practical design, however, the real trick is to compromise these guidelines and rules when [...]
5G technology change, radio frequency is the most significant, PCB both offensive and defensive The wave of 5G construction that will start in 2019 will open up new space for the upstream industry. Considering the increase of frequency and reduction of time delay, 5G is not only different from 4G in system architecture design, but [...]
The price of PCB is something that many purchasers have always been confused about, and many people would also question how to calculate these prices when placing orders online. Now we will discuss the components of PCB price together. I. different materials used in PCB cause price diversity Common double face plate is an example, [...]
Those who have experienced electromagnetic interference and those who have not. With the increase of PCB routing express, emc design is a problem that we electronic engineers have to consider. For a design, there are five important attributes to consider when conducting EMC analysis of a product and design: (1) key device size: the physical [...]
Emi problems in printed circuit boards include common impedance coupling, crosstalk, radiation from high-frequency current-carrying wires, and induction of printed lines to high-frequency radiation. The following describes the PCB design in order to meet the electromagnetic compatibility must pay attention to matters. 1. The common impedance coupling problems in PCB for analog and digital circuit [...]
Before designing a multilayer PCB, the designer needs to first determine the structure of the circuit board according to the size of the circuit board, the size of the circuit board and electromagnetic compatibility (EMC) requirements, that is, to decide whether to use four, six or more layers of the circuit board. After the number [...]
Circuit design is a basic skill for an electronic engineer. However, even if the circuit schematic diagram is perfect, if the common problems and challenges are not understood and prevented in the process of converting to PCB circuit board, the whole system will still be greatly compromised and will not work at all in serious [...]
