Best way to connect pads with the same signal

(1/2) > >>

Hi,

I'm working in a new PCB and I wanted some advice in which is the best way to connect pads that have the same signal i.e. Ground or power signal in power IC's.

Here are three examples. Which of this is the best way to do it? Is there a better one?

Thank you.



Kremmen:
The chip pretty much dictates the way you have to connect. For solderability, you should make the connections cleanly; in that sense the bottom left is a bit messy as pads and traces get mixed.
Electrically, supply should be low impedance i.e. wide tracks, use planes, and above all put bypass caps right next to the supply entry pads. The cap should be already visible in the screengrab you attached.
The cross connections between adjacent pads probably don't do very much unless the pads draw significantly different currents. On the other hand they won't hurt much either.

Hi,

Thanks for your tips. The bypass caps are not visible because I moved them away to clearly show my point. So by your comment I guess the one in the middle would be the best solution.
That's what I expected since the one in the left I only use it when I need to draw substantial current and I will solder by hand.

Thank you!

I've moved away from connecting adjacent pads straight across as it makes it harder to visually inspect for shorts after manual soldering.

+1 for this.
