Dear Experts,
I have a question about how to calculate maximum current that can be provided
by one via. In my layout, oscillator's GND pin only have one via to GND plane.
From oscillator datasheet, it says the component needs about 36mA current. So I
worry about current capacity of the GND via. The via that I used is 12mil hole
diameter and 24mil pad. It's difficuit to add two vias in layout due to limited
PCB space. Does any body can tell me how big current can be provided by one
12mil-24mil via ? Thanks a lot!
