Gerber output vias and pads are filled

Former Member

 

After creating top layer gerber data, I viewed the result with a gerber

viewer program. I notice that the pads haso no drills, they are fully

filled. Is it the way pcbs are produced?. The Holes of the vias are

drilled after photoengraving by drill bit, SO the holes of the vias are

not photoengraved?

 

The check: pads filled is always check, by the cam processor.

 

Which method is better, photoengraving the copper and then drilling it,

or the copper of the hole is not etched and the via/pad is produced only

by drilling.

    Tstbeyaz,

     

    There are software packages that will leave the pads (drill holes) open

    where the holes will be drilled.  This is old technology and created for the

    days when hand drilling was the standard practice.  This is long since gone

    and it is preferred to have filled (solid) pads in order to ensure plated

    through holes.
