Need some help with a simple PCB Design.

Community PCB Design

Greetings… I’ve just decided that I need a PCB designed for a graduate project.

I have no experience with electrical engineering and could use some help. I plan on ordering the PCB online will need some help getting the correct design submitted.

The design is very,very simple and I would like to submit a drawing of what I am looking to design. If somebody could assist me translating my drawing for a correct and functional PCB layout. That would great. I suspect it would take just a couple of minutes to look at it.

Thanks

I suggest following an existing tutorial. For instance, the SFE Eagle Tutorial:

I looked at Eagle and its a large learning curve for what I need to do. I just need two pads for connecting +/- power leads and and several holes to solder wire to access those power leads.

The holes need to accommodate 18guage strand wire. The input power pads need to big enough to solider on 12guage strand wire.

The board itself is only 2"x2" each side has 6 holes IE three sets of -+.

That’s really about it.

If you’re just trying to make a tool to breakout some power leads - I’d suggest you’re using the wrong tool for the job. Direct Wire->PCB connections are fragile. Given the sizes of your wires; you also would need a fairly heavily plated PCB to carry currents that those wires would be capable of.

Why not just use a terminal block, or even just solder the wires together in free space, with shrink tube to protect the soldered connections? [Strain relief would be a good idea for either of these]

I think this may be what your looking for:

Theres many other flavors, just do a google search for “car audio power distribution block”

Thanks David… This is a modified replacement for an existing board… The board is for RC an aircraft so it has to be light and small… Currently the board requires several auxiliary boards be soldered directly to it. The problem is that if there is a problem with one board all the boards need to unsoldered to diagnose the bad board. Right now there are 4 solder connections per board and there are 6 boards that attach this existing board.

My goal is to build a replacement board that uses connectors so that the auxiliary boards are plug and play.

This can be done quite easily with point to point perfboard. No need for a PCB. What kind of connectors are you using?

I was going to try a perfboard but I don’t trust my skills. lol I have a perfboard and some jumpers but designing the routes isn’t making much sense to me right now.
