Sparkfun PCB design tips were very helpful. But i got stuck at a tented pad? I checked “tStop” and “bStop” layers while turning off others and it seems everything is fine with the hashed boxes on the pad in question!
I usually run Eagle3D to get an idea of the board and the capacitor pad seems tented (see attached file) while other pads look fine :?
I like to tent vias too, because it looks good. But I have been reconsidering the idea. No guarantee the soldermask goes all the way through and protects the copper inside the via, so there may be a higher risk of corrosion there. Vias with the same plating as solder pads may be more durable.
However this isn’t about tented vias, but component pads that appear tented. Without seeing an Eagle screenshot or file it’s impossible to tell what’s wrong. I’d suspect an improperly made part, or else a fill rectangle or a polygon with priority set too high.
Think I found the issue , looks like Eagle3D has an option to draw holes real mode or fast. If you select fast mode , the issue is fixed.
However if you go with real holes , any hole within a copper pour and has a diameter over the diameter setting (Eagle 3D window / Board tab / real holes from(mm) = 2mm for example) will get covered up.
I increased it to 2.5mm and it rendered correctly , decreased it to 0.5mm and more pads got tented.
