Basic PCB help please

Hi all,

I need to get a generic spread of PCBs made. They are all just basic pass through electrical contact type, and all are round. No components will go on them.

I’m looking to pay someone to make the files. If you’d like to do this just shoot me your price. If you want flashlights I have a few I could spare in trade if you prefer :slight_smile:

What I need are just basic round pcbs with a ring around the rim, and one in the center, like you would commonly see on a flashlight driver board. The center ring needs to accommodate an 11mm diameter spring. On the larger diameter boards the center pad for the spring could be larger. The boards will look the same on both sides, and have vias to connect the two sides electrically. High drive currents should be assumed so heavy traces etc would be good.

Something like this, but without the large wire hole in the center.

The sizes I want are 17,20,22,24,26,28,30,32 mm diameter. I also intend to order a duplicate set of the pcbs that are single sided.

Where do you plan to have them made?

OshPark only offers 2oz on the .8mm pcb which probably wouldn’t be sturdy enough.

The copper weight doesn’t matter much with large zones like this, and especially it’s mostly travelling through the vias.
I can do this tomorrow, I’m heading to bed now :yawning_face:

Complicated software is not needed for such projects. You can use sprint layout, it is as easy as Paint for windows.

I will probly use OSH park, but I’m okay with any where that has an express service option. I would prefer to use thicker boards. The ones I have here are like 1.69mm thick. I thought they had heavy traces but maybe I’m wrong. I was kind of hoping for 2 oz but I can probly get by with less.

Bump. I’m still looking for an interested party to do this :slight_smile:

Easy can do it . Kind of… same from both sides?

1 Thank

Yes, the same on both sides, but I need to be able to solder a spring directly in the center.

Thanks. That looks pretty close to what I need. I would like to get them in the sizes I have listed in the OP. You can either PM me or shoot me an email if you like to let me know your price for doing them, if you would like to help with the entire batch. matt@lumencraft.com
