10 stupid things people do in drawing circuit diagrams

1,  The pins are upside down in polarized capacitors

2,Sometimes,you might forget to connect the power and ground by capacitors

3, The line order of connector line  are in reverse .

4, RX and TX are reversely connected .

5.Directly copy the circuit diagrams from the internet, and then when you prepare to buy the materials,you suddenly find those components are unavailable .

6,When selecting the capacitor, you just only consider the capacity without considering  the pressure.As a result,the capacitor can not fit in such a large package

7, When selecting the resistor,only consider the resistance, do not care about the power consumption.

8, Directly aim at the fly line by eyes,do not check the DRC report.

9.Anti-packaged

10,Do not deal with the solder mask on the thermal pad.
