Questions about the card edge connector



I have a couple of questions about the PCI card edge connector that don't
appear to be answered in the PCI Local Bus Specification, Rev. 2.1:

  1. Is there a specified plating composition and thickness for the
     tabs on the card edge?  On page 180, table 5-1 gives the contact
     finish requirements for the motherboard connector.  I can't find
     an equivalent specification for the tabs on the card edge.

     If there is no specification for card edge tab plating, what is
     generally used by manufacturers of high-quality products?

  2. Is a radius specified for the end of the keyway, or is it assumed
     to be the same as the half-width of the slot (0.0365" +/- 0.001")?

Thanx!
