Hi,


I have to modify a 4 layer pcb in PADS software.

The problem with the previous design is the trace used for high current path is fused away.

Can I use multi layer traces(for all 4 layers) for the same connection with wide traces(including ground layer)???

Can anyone suggest me something about this???

Thanks regards,
Vivek Alaparthi

 

I don´t see a problem with using all 4 layers to do the connection. What is the current through that part? Are you sure it´s the trace and not the vias that fuse?
Can you post a schematic for the board? And maybe keep one design in one thread?

 

Use airwires soldered to PCB pads for anything >5 Amps.

 

Hi kubbek,

Thanks for your reply


The design given above is mine not the previous one

There is no problem with connection.

My doubt is that, i have given traces in all 4 layer for same connection including ground.

Does that mean these components are grounded or not.

Can I use ground layer also for connecting traces to components(data lines and power), if no net is assigned in that plane area???

I am attaching schematic with this post


Thanks & regards

Without having a schematic it is hard to tell. Maybe you do not need four layers at all.

 

Hi to6afre,

Have you checked the switching times on those transistors? At what frequency are they switching? What is the peak current?

As for the board connections, you can look at the output gerber files and see what is connected to what. I use gerberlogix for this, one of those grber viewers that actually work.
