The purpose of this test is to verify the resistance to electrostatic discharge (ESD) caused by the approach or contact of objects or people or devices. Or people’s interior can accumulate electrostatic charges higher than 15kv voltage. Experience shows that many unexplained failures and damages are probably caused by ESD. Through discharging from the ESD […]

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 […]

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 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 […]

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 […]

Now there are more and more electronic devices, and many things are developing in the direction of intelligence, which requires more circuit boards to undertake the control systems of these devices. Here’s how to choose PCBA processing technology for circuit board processing. How to correctly select PCBA processing technology for processing circuit board 1. single-sided […]

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 […]

After importing the design data, the PCB design engineer will start the PCB layout design. The quality of layout often determines the success or failure of veneer. What are the layout problems we encountered in those years? Have you laid out the layout and found that there is no room for punching holes? The extra […]

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 […]
