　　1. Drilling:

　　A: Select Reference Point: Select the hole (that is, a hole in the first drill) as the unit reference hole.

　　B: Each blind hole drill must be selected to select a hole to mark the coordinates of the reference hole of the relative unit.

　　C: Pay attention to which layer of the corresponding layer of the drill belt: the units and the drilling table need to be indicated, and the names of the front and rear must be consistent; the perfuging chart cannot be represented by A B C, and the front is represented by 1ST, 2ND represented by 2ND Condition.

　　Note that when the laser holes are put together with the inner buried holes, that is, the holes of the two drills are in the same position, and the position of the guest moves the laser hole to ensure the electrical connection.

　　2. Production PNL board edge process hole:

　　Ordinary multi -layer circuit board: inner layer does not drill holes;

　　A: Rivet GH, AOI GH, ET GH are all eclipsed (beer)

　　B: Target holes (drilling GH) CCD: The outer layer needs to be pulled out of copper skin, X-ray machine: directly hit, and pay attention to the minimum of 11inch.

　　Blindhole board: All Tooling holes are drilled out. Pay attention to rivet GH; beer is needed to avoid the deviation. (AOI GH is also beer), the production of PNL boards needs to be drilled to distinguish each board.
