    is it a good idea to stitch 4 copper polygons together to increase current capabilities?

    Hi all, I have a 4-layer PCB with a below layer-stack and I will be having a net that is supposed to handle 100A. I know I should use a heavy copper PCB instead of this 4-layer PCB but to save cost I stitched 4 polygons on all layers with (0.5 hole size, 1 diameter) vias to accommodate the high...

    Via designing

    I have a few basic question about the usage of vias on my PCB design. On this image I'm wondering if the via coming of the 3.3v seem fine, as the lines go further on the bottom powering 5 relays with the same design on them all. Second I'm wondering if the 90 degree on the bottom trace would...

    Can you route multiple return traces to the same via?

    New to PCB Design and layout. While routing bypass caps, I instinctively give each bypass cap its own via to the ground plane. What would be the disadvantages of having two (or more) bypass caps share the same ground via? I suspect the consequences are more apparent in high-speed and/or high...

    How to use ground stitching and shielding?

    Hello guys, I was wondering when ground stitching 2 ground layers, what kinda pattern and spacing I should follow to place vias? and should I use more vias near components/pads that dissipate more heat? As for shielding, Is it only used in RF boards or it doesn't matter!! And if someone can...
