Sure…

What are guide rings? :8)


Like SinkPADs have, so you can grind a circle…

Yes.
Oh yes. Beer

Just following your OSH Park ‘shopping cart’.
Cool stuff.
It’s more than late where I’m from, thanks a lot so far, will look again tomorrow.

You can add those with tDocu and bDocu, part of the silk screening

Did a tweak to wight’s .brd file (just added the white rings is all)

Files here

I haven’t shared it…if you would like it shared let me know

Very cool having a modular type contact ring that with a little grinding can make fit multiple pills

Here is Mattaus’s CAM processor that I added the top and bottom cream layer…just put in the cam directory of Eagle install, when you get your board built save it, open the CAM processor, open the board, generate, zip up the all caps files and upload to OSHPark, you can also upload to OSHStencils and select the correct cream layer for a stencil

EDIT: You cannot just add those with tDocu/bDocu. I know some people will TLDR Wink

Oshpark frequently cannot keep the silkscreen aligned with the rest of the board – adding thin rings is asking for misalignment. That said, there’s a bigger problem with your suggestion. You can’t silkscreen bare copper. Silkscreen is only allowed on mask, it gets automatically removed otherwise in the production process. Therefore you must manually lay down mask rings or the silkscreen generated by tDocu/bDocu will never show up in the finished product. Since the mask is a negative layer and we want to laydown a positive, it’s already a big pain to add the guide rings. If you don’t know what I’m describing there just fire up Eagle and try to make another mask ring or two at something like 23mm.

So IMO silkscreen rings just makes the board look sloppier after production and adds extra work / gets in the way inside Eagle.

right…you can’t put any silkscreen or mask where tStop and bStop are…those rings tDocu/bDocu were just added over the top of your mask rings…but as you said…alignment sucks bigtime (I don’t think the bottom layer has the rings, the bottom image showed them there…but the bottom of your .brd is all copper I believe, the top had the concentric rings of mask above

Thanks a lot. This is everything that could be hoped for. Moving the vias to the thicker regions was a good idea, this will increase stability. And the guide lines should be truly helpful. I did set up an OSH park account (only had ordered a stencil yet) and have now ordered 26mm (v11) and 22mm (v9b). More than happy I am.

I opened 26mm (v11) in Eagle and separated all parts to understand them. Two things seem weird.

The tStop layer (29) seems to be the complete opposite than in the oshpark picture. Solder mask everywhere but not in the small guide rings. Shouldn’t it be the other way round? The bottom layer is completely covered with a bStop layer as well…

Over the vias are red shaded cicles, belonging to layer 1, that are unmovable and unclickable. I can move the 26mm red cicle of layer 1, but not the 8 small ones.

I use Eagle 6.5.0 light, could that be a problem?
Thanks again.

Your Eagle version is fine.

Stop layers are negative – they define where we do NOT want solder mask applied. Generally speaking, most PCBs require solder mask everywhere with a few exceptions, so negative makes sense in a normal application.

Take a screenshot of the red shaded circles, I’m not really sure what you are running into there. Actually, most likely thing is that you ran a DRC from the Tools menu or the tool pallet. If that’s the case you must run a DRC again and this time clear all errors – those are overlap warnings.

Repeatedly right clicking may help you select the appropriate items. If I continue to right click Eagle will select things one by one through the stack under my cursor. Those circles should be easy to select though. Things get harder to select when stacked deeply. Also some items (not those circles) will require the appropriate Origins layer to be turned on, and you grab them using the little origin symbol.

Still fine, still on a break. One day I’ll catch up with you folks! previous wight catchup Wink

Yes, that’s exactly what it was. I must have clicked there while trying to get a grasp.
Left me quite dumbfounded.

That’s very very good to know.

Thank you very much. I will stop now asking layman’s questions, you did help me more than enough.
Just got the “assigned to panel” info from OSH park, by the way. Smile

I made a thread for the latest revision of the 26mm board here. v13 is meant to be attached to a mandrel in a drill or dremel and filed down that way before breaking out the center area.
