. I've tried plated and non-plated hole but with same results. I know I can put some copper on the top layer but I'd like to figure this out in case I come across a case where that's not an option

. Laser direct imaging exposes certain parts of the board to light in the shape of the PCB pattern. Any unexposed parts of the board will develop off, leaving the remaining film as an etch barrier The remaining film serves as an etch barrier that will be removed from the exposed copper to form the copper circuitry

: This printed layer contains labels, symbols, and markings for components. Vias: Small holes drilled through the PCB, often plated with copper. Pads

;The pad master was over-exposed to create the solder mask swell. The PCB’swhere created using the negatives to apply a temporary mask that protects partsof the copper laminate from acid and leaves the desired pattern

. For Non-Plated Through-hole the "b" dimension should be larger than the hole size. Probably the hole tolerance +/- 0.05 annular ring. If the hole is non-plated, you want the drill bit to go through FR4 material and not touch any copper to avoid copper slivers in the hole

. Sufficient inner clearances help ensure that your drill does not cause shorts to your inner copper layers. This is important for both plated and non-plated holes, as non-plated holes may either cut into an adjacent trace or cause shorts during assembly. Requirements: A minimum of .012
