Drilling is the most expensive and time-consuming process in PCB manufacturing. The PCB drilling process must be implemented carefully, as even small errors can lead to significant losses. The drilling process is the most critical process in PCB manufacturing. It forms the basis for the connection between through-holes and different layers, making drilling techniques very … Read more
In the circuit board manufacturing process, panelization is a crucial step that can enhance the production efficiency and product quality of the SMT assembly line. It is a key topic that many engineers need to focus on. However, many people learn about panelization too theoretically and are not very familiar with most of its content. … Read more

Simplified method for using JLINK to download programs to STM32 via JTAG interface (SW and JTAG modes)! Anyone who has used STM32 knows that there are two common methods for downloading programs: via serial port and JLINK. The serial port download method is quite similar to that of the 51, so I won’t elaborate on … Read more
During the home renovation process, the renovation team discovered a screw connected to a cable, and the electronic device at the end of the cable turned out to be a CCTV camera. Although the casing broke after unscrewing the screw, I was still able to capture the internals of the camera (the following photos show … Read more
When passing the PCB schematic to the layout design, there are six key considerations. All examples mentioned are developed using the Multisim design environment, but the same concepts apply when using different EDA tools! Initial Schematic Transfer When transferring the schematic to the layout environment via the netlist file, device information, netlist, layout information, and … Read more
Welcome to Reserve IIC Shenzhen – 2023 International Integrated Circuit Exhibition and Seminar Live Broadcast Previously, we disassembled two multimeters, both of which were low-quality counterfeit models that were just usable.
