Mastering the Craft of NumPad PCB Design: A Comprehensive Guide Numpad PCB design (Printed Circuit Boards, or PCBs for short) holds a central place in computer hardware design. PCBs form the backbone for electronically controlled equipment – including our number pads or “Numpads.” With custom keyboards becoming more prevalent than ever, understanding Numpad PCB design […]

PCB design flow: Please pay attention to these “6 precautions”! The physical design of the board on the switching power supply is the final link. If the design method used is not suitable, then the PCB could radiate excessive electromagnetic interference, leading to unstable power supply operation. 1. PCB design flow: From the schematic to […]

5 common PCB design problems you encounter. 1. What is the 20H principle in PCB design problems? The 20H principle is the shrinking distance of the power layer from the ground. It is also used to suppress the edge radiation effect. The board’s edge will emit electromagnetic interference outside. The EMC is improved by shrinking […]

Why PCB design generally controls 50 ohm impedance? A large portion of electronics technology originated in the military, first the technology was used in the military and slowly moved from military to civilian use. In the early days of microwave applications, during World War II, the choice of pcb design impedance depended entirely on the […]

Why do PCB multilayers have an even number of layers? Can’t an odd number of layers work? PCB is divided into a single panel, double-sided boards and multilayer boards, which is unlimited number of layers of multilayer boards, there are more than 100 layers of PCB, and the common multilayer PCB is a four-layer board […]
