MUR Bridge on a PCB

D_GR8_1 · 23rd November 2004, 06:39 AM

Im making a Reg PSU PCB and I am trying to implement it on a one sided design.

However, I am having trouble with the bridge connections.
Whichever way I connect they seem to overlap.

What's the easiest way of doing this?

I don't know exactly what you mean but do you mean that you can't solve it without jumper wires? Do you have a picture of your efforts so far?

D_GR8_1 · 23rd November 2004, 06:51 AM

I was hoping not to use jumpers.

Why don't you just move the diodes a bit? If you don't plan any additional cooling you can also twist the diodes so it makes it easier for you.

That's exactly the question of my post.

How do I arrange the diodes?

D_GR8_1 · 23rd November 2004, 10:28 AM

No one can give me any ideas on how to position the diodes?

It's pretty simple

Just copy a 'block' high current bridge.

What do you mean?

I have 4 single diodes, not 1 diode bridge.

Also, I am trying to avoid making the PCB double sided.

If it makes it easier for you, draw all traces frist and then move the diodes.

Think how a rectifier bridge looks like, the convert it to four separate diodes.

peranders, I have done that. I even tried placing traces under the actual diode, but the trace width that I use (5-10mm) actually doesnt make this possible.

What I am asking for is for someone who has already done this to post a picture of it or something.
