Confucius said: “When you see someone virtuous, strive to be like them; when you see someone unvirtuous, reflect on yourself.”—— from “The Analects of Confucius, Chapter on Benevolence”
Explanation:When you see someone with better character and ability than yourself, you should think about how to work hard to be like them; when you see someone who is not as good as you, you should reflect on whether you have the same shortcomings.
Have you encountered any of the following 11 issues?
1. Did you reverse the pins of a polarized capacitor in the schematic and PCB?
2. Did you forget to connect the power and ground… or connect them incorrectly?
3. Did you reverse the pin order of a connector?
4. Did you connect RX and TX incorrectly?
5. Did you naively write a package, only to find that there is no component of that specification? You downloaded the datasheet from Baidu Wenku, but the component is not available for purchase.
6. Did you directly copy a circuit, only to find that the components are not available?
Once, a team working on smart locks directly copied the circuit from Samsung’s smart lock, only to find that a capacitive touch button controller inside was made in Korea and very hard to obtain, with no agents or support available. They had to rely solely on their own experiments and explorations.
7. When selecting capacitors, did you only consider the capacitance without considering the voltage rating, resulting in a package that is too large to fit the required capacitor?
8. When selecting resistors, did you only look at the resistance value without considering the power rating?
9. After finishing the PCB, did you not check the DRC report and relied on your eyes to check for flying wires, only to find that there were indeed flying wires after the board was returned?
10. Did you make the package incorrectly?
11. Did you neglect to process the solder mask layer for the heat dissipation pads?
