Safety distance includes electrical clearance (space distance), creepage distance (surface distance) and insulation penetration distance. Electrical clearance: the shortest distance between two adjacent conductors or one conductor and the adjacent motor housing surface measured along the air. Creep distance: the shortest distance between two adjacent conductors or one conductor and the adjacent motor housing surface…
A classic PCB temperature profiling system consists of the following components: · Data collection profiler, which passes through the middle of the furnace and collects temperature information from the PCB. · Thermocouples, which are attached to key components on the PCB and then connected to the accompanying profiler. · Thermal insulation, which protects the profiler…
Electromagnetic interference is widely present in various types of electronic and electrical equipment. Various electronic and electrical equipment will more or less emit electromagnetic waves when working, which will interfere with the normal operation of the entire equipment. In the design of electronic products, due to insufficient consideration of electromagnetic compatibility, some electrical and electronic…
Static electricity from the human body, environment, and even inside electronic devices can cause various damages to precision semiconductor chips, such as penetrating the thin insulation layer inside the components; damaging the gate of MOSFET and CMOS components; locking the trigger in the CMOS device; short-circuiting the reverse-biased PN junction; short-circuiting the forward-biased PN junction;…
The earlier the signal integrity (SI) problem is solved, the more efficient the design will be, thus avoiding the need to add termination devices after the circuit board design is completed. There are many tools and resources for SI design planning. This article explores the core issues of signal integrity and several methods to solve…

Shortening PCB design cycles has become a regular issue. Designers are also facing drastic changes in circuit board technology, such as faster processing speeds and increasingly complex IC packages, which add complexity to PCB design, which is the simplest part of the design process. Therefore, in order to improve the efficiency of the design process,…
Introduction In the world of modern electronics, thermal management is a critical design consideration. As the power density of electronic components continues to increase, effectively dissipating heat has become essential to ensuring device reliability and performance. Aluminum-based PCBs (Printed Circuit Boards) have emerged as a highly effective thermal management solution, widely used in high-power LED…
1.Introduction With the increasing complexity and performance of electronic products, the density of printed circuit boards and the frequency of related devices are constantly rising. Maintaining and improving the speed and performance of the system has become an important issue for designers. The higher the signal frequency, the steeper the edge, the smaller the size…
With the advancement of electronic technology, the complexity and application scope of PCB (printed circuit board) have developed rapidly. Designers engaged in high-frequency PCB must have the corresponding basic theoretical knowledge and rich experience in high-frequency PCB production. In other words, whether it is the drawing of the schematic diagram or the design of the…
Due to the increase in system clock frequency and rise time, signal integrity design has become increasingly important. Unfortunately, most digital circuit designers do not realize the importance of signal integrity issues, or only realize it in the final stage of design. This article introduces the impact of signal integrity in high-speed digital hardware circuit…
