Any advise to a new comer/learner?

Hi,

 
I am designing a PCB which needs to escape a lot of cylinder protrusions. So i need to drill many through holes of different sizes. Many of the holes are quite large (diam.15mm) and the PCB house cant do it.So, can i just take it to our CNC machine and drill it ourselves? Will it break the PCB (polyimide material)?

How do i add a gold finger connector to my PCB (so it looks like a card) in Capture? or can i only add it in Layout or Designer? i tried using CONN PCB 10x2 with a modified footprint of XT/FINGER ( deleted the extra pads so only 10 pads left on Top and Bottom layer) but it says "at least one pin from the connector has no coresponding pin on the footprint".

 I need to do routing which starts from the gold finger pad and ends at the same same gold finger pad (sensors flush mounted on PCB and soldered both sides to the trace). Do i a via to do that?

 

Attached is a picture of what i hope to accomplish. It ishows the Top layer . The bottom layer is identical. It is a double sided PCB.

 

Any help/hints are greatly appreciated. Thanks.

    Hi, i tried figuring out myself but i need some feedback on my methods...not sure its the right way...or if it is doable.

    So for the through holes, basically i have to create lots of mechanical symbols of padstacks for each hole size and add it in one by one? if so which class should i add it to?

    And for the component mounting holes (which are also through holes but with copper trace leading to it), i have to create symbols with "connect" pins right? Then i just add connections and draw out the artwork to follow the sample above right?

     The PCB board has a few sensors flush mounted onto it and soldered to the copper traces on both sides.

    By doing it this way, can the PCB be fabricated with the NC drill file and the gerber file alone? I did not create a netlist because i dont know what component to place as the finger/tongue.
