Every PCB question I have seems to lead me back to Zach Peterson. Thanks for all your work!
Keep the questions coming!
Very informative video
Keep making such kind of videos
Thank you
Nice video!
As a note: 1oz copper = 35µm is used sometimes as a measurement in Europe
But what is the area of the pcb ? 1oz copper on 100 x 100 mm board is thicker than 1oz copper on 200 x 200 mm board.
never mind i got the answer.
@@shadowshadow2724 what’s the answer?
Nice topic.!! thanks..!!
Glad you liked it
great video, please make more videos on power electronics layouts. please consider an explanation video on high voltage clearance too. thanks.
Noted
The cross section is used for current density analysis and it is used to gauge the current and to ensure we don't burn out the trace, copper migration etc... if you run PDN simulations you will need those boundaries in A/mil^2. The IPC standard is good starting point though.
Yeah agreed, I like the IPC standards as a starting point but DC analysis in the PDN will be much better for targeting specific areas that might need changes.
That was really a great go through, I have one question, Is there any trace width calculator available into altium software ?
Hi Harish, Yes there is a trace width calculator for controlled impedance. It is located in the Layer Stack Manager. You can follow my process here: ua-cam.com/video/4LwnEaNvG8I/v-deo.html
What about minimum track width, annual ring and minimum distance between trakcs ?
We finished recording a video about these points last week, it will be up soon. Stay tuned!
