1 Component Placement When placing components, it is essential to follow the signal paths of the schematic and provide space for routing. Additionally, adhere to the following placement rules: Power components should be placed compactly together, with appropriate decoupling to ensure power integrity. Decoupling capacitors should be placed as close as possible to each component. … Read more

“Rounding, what’s so difficult about it?” When you hear this term, do you immediately think of your elementary school textbooks? However, in computing, especially when dealing with floating-point numbers, things are far from simple. When we mention rounding of floating-point numbers, we often refer not to the most common “round half up” that we encounter … Read more
Hello everyone, I am the Intelligence Guy~ First of all, Electrostatic Discharge (ESD) refers to the phenomenon of charge transfer that occurs when objects with different static electric potentials come close to or directly contact each other. ESD testing is a type of reliability testing for electronic products, measuring the product/system’s resistance to interference from … Read more
Identifying the Cause of Interference When there is interference on the bus, experienced engineers can quickly locate the issue, but it can be troublesome for beginners. There are many causes of bus interference, such as electromagnetic radiation coupling into communication cables, improper grounding of shielded wires, and isolation of communication without isolating the power supply. … Read more
Example 1: Input a time duration (in minutes) from the keyboard and calculate how many hours and minutes that duration corresponds to.(1) Source Code #include <stdio.h> #include <stdlib.h> int main(){ int a,b,c; printf("Please enter a time duration (in minutes):"); scanf("%d",&a); b=a/60; c=a%60; printf("%d minutes is equivalent to %d hours and %d minutes\n",a,b,c); return 0;} (2) … Read more
Numerous application cases of Industrial, Scientific, and Medical Radio Frequency (ISM-RF) products indicate that the printed circuit board (PCB) layout of these products can easily exhibit various defects. It is often found that the same IC installed on two different circuit boards can show significant differences in performance metrics. Variations in operating conditions, harmonic radiation, … Read more
