Hi,

Perhaps there is someone who knows what this is about:

We tried out a new pcb supplier. The first protos were fine, and we
purchased a bigger batch.
Even these pcb´s looked fine, with an exception; All the pads were rounded,
so they haven`t
used our apertures at all !!
Rounded apertures are for my part OK, but question remains, how this could
possible happen.
I asked this question and I got this as an answer:


     "The reason of the problem is human error.  For any new P/N we load
the Aperture
      Wheel in our Cad system in this case the operator made a mistake (
didn't consider
      the shape 1-2).
      To avoid this problem on the future production, we propose:
      -Aperture wheel standard
      -Specific program-script to load the aperture wheel in automatic way
in our Cad system"

Forgive my ignorance, but I don`t know what is:

-P/N
-Aperture Wheel
-Which kind program-script is he/she referring to ?

I am asking this because so far I haven`t got the answer  from the
supplier. I am just curious.

Brs, JoSi
