There are two types of engineers in the PCB industry. One type of designer possesses specialized knowledge and adheres to strict design standards. Their network wiring, surface mount components, and text are well-organized, with reasonable layout in functional areas that facilitate production optimization. They communicate smoothly, are open to suggestions, work efficiently, and handle their … Read more
Last year, I assembled an amplifier board using two LM1875 chips for ceiling speakers in my shop, which has been in use ever since. Recently, I found a BBE sound exciter board online, which is said to enhance high-frequency details and improve low-frequency performance. However, since this BBE exciter board has its own bass and … Read more
Flex Power Modules has launched an upgraded version of its BMR510 2-phase integrated power module. The new BMR5101041/002 version not only improves efficiency and increases the peak current from 140A to 160A, but also includes a 528μF onboard output capacitor, significantly enhancing transient response. This onboard capacitance reduces the need for customers to add external … Read more
Hello everyone, I am Goat. Continuing with some other signal quality issues related to I2C. If you encounter these problems, how can you resolve them? Back Reflection Back reflection poses significant risks to clock-type signals, and since the I2C CLK signal is a clock-type signal, the presence of back reflection can lead to sampling errors. … Read more
