Typically, the current design for PCBs does not exceed 10A, especially in home and consumer electronics, where the continuous working current on a PCB usually does not exceed 2A.However, some product designs for power traces can sustain continuous currents of around 80A. Considering instantaneous currents and leaving a margin for the entire system, the continuous … Read more
I exerted a tremendous effort to finally blow off the STM32H753 with over 200 pins from the PCB using a hot air gun. I breathed a sigh of relief, silently hoping for a miracle. We need to design a new project, and after extensive analysis and consideration, we finally chose the STM32H753 chip. Due to … Read more
The PCBA processing costs consist of the following parts: PCB Board Cost (If you provide it yourself, there is no charge) Component Procurement Cost (If you provide this as well, there is also no charge) SMT Processing Cost (SMD Mounting + DIP Soldering) PCBA Testing and Assembly Cost 1. PCB Board Cost If you want … Read more
SMT Top Networking Circle A professional circle for sharing networking resources and achieving career advancement. In simple terms, the PCBA process is a combination of the SMT processing and DIP processing. Depending on the requirements of different production technologies, it can be divided into single-sided SMT assembly processes, single-sided DIP insertion processes, single-sided mixed assembly … Read more
Simply put, what is PCB? PCB = printed circuit board; the Chinese name is 印制电路板, also known as printed circuit board, is an important electronic component, serving as the support for electronic components and the carrier for electrical connections between electronic components. Because it is made using electronic printing techniques, it is called a ‘printed’ … Read more

Abstract: By researching the factors such as different line widths, different dielectric thicknesses, variations in dielectric constant, layer browning, and line compensation, this study analyzes the main factors affecting PCB impedance and the varying degrees of impedance influence, providing the best recommendations for high precision impedance design of PCBs. 0 Introduction In the integrated application … Read more
Conformal coating is a specially formulated paint used to protect circuit boards and related equipment from environmental corrosion. Conformal coatings have excellent resistance to extreme temperatures; once cured, they form a transparent protective film that can protect circuits from damage under conditions such as exposure to chemicals (e.g., fuels, coolants), vibrations, humidity, salt spray, moisture, … Read more
1. PCB Protection Design Principles• Shielding Measures: Use metal enclosures, conductive coatings, or shielding covers to shield the equipment, reducing electromagnetic radiation and interference.• Grounding Design: Reasonably layout a low-impedance grounding network to avoid ground loop interference, ensuring the device grounding terminal is well connected to the earth.• Layout Optimization: Separate analog, digital, power, and … Read more
