Dear friends,


is there any rule that I should do the size of the port pin ? or it is just like a label and has no electrical proprieties or influence

Thank you
 

It’s about location. As long as it’s covered entirely by the layer it’s on and your label is within the pin, the dimensions don’t matter
 

Dear ljp,

Thank you for your reply,

Then why I see some people in youtube makes the port pin for VDD and GND very big ?
 

Various reasons. Visibility on large layouts, requirements for various tools, etc.
 

Thank you for your kind answer,

No I am confirmed that pin size has no affect on the electrical proparties of the circuit
