PCB Design Goal of DC Motor Drive Circuit In the design of DC motor drive circuit, the following points should be considered: 1. Function: Does the motor rotate unidirectionally or bidirectionally? Don’t need speed regulation? For unidirectional motor drive, only a high-power triode or FET or relay can directly drive the motor. When the motor […]

In a grounded desktop product, when the ESD contact discharge test with a test voltage of 6KV was conducted at the grounding terminal, the system was reset. In the test, try to disconnect the grounding terminal from the Y capacitor connected to the internal digital working ground, but the test result has not improved significantly. […]

With the development trend of miniaturization and thinness of electronic products, many circuit boards in electronic products now adopt SMT manufacturing technology, that is, surface mount technology, that is, all electronic components are attached to the surface of circuit boards. There is no need to insert it through the reserved via hole on the circuit […]

1 Why do you want to divide digital ground and analog ground? Although it is interlinked, it is different when the distance is long. The voltage at different points of the same wire may be different, especially when the current is large. Because there is resistance in the wire, the voltage drop will occur when […]

In the process of PCB outsourcing design, especially in high-frequency circuit design, some irregular and abnormal phenomena caused by ground wire interference are often encountered. In this paper, the causes of interference caused by ground wire are analyzed, three types of interference caused by ground wire are introduced in detail, and solutions are put forward […]

The increasing importance of laminating and laminating technology in all of these industries, including PCB, is increasing rapidly. In order to prevent quality problems, such as dislocation, during lamination, it is usually required to integrate PCB manufacturing processes before lamination. Compared with traditional fusion technology, modern fusion technology has the advantages of high efficiency, easy […]

Pcb circuit boards that provide power supply are almost all called power boards, and power boards are machine boards that mainly deal with power supply initiating functions. The smt process flow of power board can be basically divided into three processes: automatic mounting of SMT components, wave soldering plug-in, and manual operation. Then, what are […]

There is a limit to how many circuits can be installed on a board. For the sake of manufacturing equipment and standard panel size, PCB itself has an upper size limit. The number of transistors on a device continues to expand, while resistors and capacitors almost disappear to the naked eye. Even with all integration […]

Some STM32 application customers who use external SDRAM reflect that in EMC test, the radiation interference caused by SDRAM signal exceeds the standard. If the chassis can’t shield the radiation interference in the terminal products, then this kind of problem often needs to be solved by modifying the PCB design of SDRAM signal. Here, how […]

The simple principle of circuit board design is that it must be suitable for its intended application, not the other way around. Therefore, as a PCB designer, you will find that there are many different PCB size and shape requirements. Here are some ideas about excellent ways to use these different circuit board dimensions. Know […]
