Hey,
I have a bunch of LEDs that i want to drive with an led driver ship (STP16CP05).
Instead of connecting every Vcc Port i want to define zones around my LEDs on the PCB back and then i want to connect all zones with traces to the Vcc Input Port, in this way i can route the signals on the top layer.
How can i connect the zones with traces or is this not possible?
Just draw tracks that start/end within the respective zones. Endpoints at pads are optimal but not mandatory
Btw, why not have a single zone including the connector’s VCC pad?
I had this idea, but because i have to route the signal lines on the front plane.
I need to roud the clock, latch and ground lines on the back plane.
when i say all the backplate is Vcc, then i cannot route them.
Or do you know a trick :), that’s my second design ^^ i am very new to pcb.
While it is optimal to have an uninterrupted GND and/or VCC plane, it doesn’t hurt if there are a few traces in the VCC plane. Especially if there are no high frequency switched signals.
Just take care there is enough connected copper for the currents required. Play around a little. Draw a zone covering the entire board. Route tracks where necessary and see how it goes.
I you want, you can upload the board for ‘review’.
hey thank you a lot, i’ll do :).
Ok.
It’s nearly 10pm where I live and the snooker WM is on 
So I’ll have a look tomorrow.
Btw, it is best to archive the whole project (File->Archive Project) and post the archive.
Yeah The Crucible trumps all PCB work

I know LEDs don’t take much current, if no no other reason than physical strength, don’t you think some wider tracks might be in order ? you aren’t pushed for space.
