I am a beginner on Eagle. I want a make a plated hole on PCB but no any pad on top or bottom layers. Or, a plated hole on PCB but bottom and top layers are electrically isolated. Another variation is plated hole with a circle only on bottom or top layer. In all cases plated hole connected with isolated copper wire (trace). How i can do this with Eagle?

\$\begingroup\$ i do small research on google, what i need is called "tented plated hole" or "solder mask aplied plated hole" \$\endgroup\$ – user30878 May 7 '14 at 9:50

\$\begingroup\$ Do you think tenting is good enough to guarantee "electrical isolation"? \$\endgroup\$ – Scott Seidman May 7 '14 at 12:37

\$\begingroup\$ I can't tell -- are you talking about a "via" (layer-to-layer electrical connection) or something else? \$\endgroup\$ – Dave Tweed May 7 '14 at 17:47

Use a via to a track and set via pad size to whatever you wish.
There will be a minimum size to obtain reliability.
Your PCB supplier will (or should) have design rules covering this.
