Dear Technetter,

You may calculate by yourself after you consider the followings(cost
involved vary from plant to plant):

1.  Master and production films for all circuitry, solder mask and legend
2.  Set up for imaging
3.  Set up for screensilking
4.  Set up of E-tester
5.  Set up of V-cutting(if required)
6.  New hard tooling or routing software modification.

Good luck.
