Hey Steve - I feel your pain!    We had a similar situation with a customer
that demanded that the action pins be soldered (may have been the same
customer).  :)      ...and we had the benefit of having our mother
companies' action pin designers trying to convince them not to it - to no
avail.  They eventually regretted it.

If I could offer you any advice, it would be to make damn sure that the
connectors are oriented correctly before you solder --  cuz you ain't gettin
em out!

As a wise man once said, "The customer is always right, even when they're
wrong"

  Hi Rich!

  This connector does have compliant pins, but AMP (Tyco) calls them "Action
Pins".
  Here's the datasheet:

  http://catalog.tycoelectronics.com/TE/docs/pdf/7/49/222947.pdf

  The holes in the board are what the datasheet calls out for that
connector, I just got through checking the gerber. Everything is set-up
perfectly to press it, and forget it!
  (where have I heard that before? Ron Popeil?...oh no, it's set-it, and
fah-get it!)

  But we're still gonna press and solder the darn thing in because that's
what the customer wants, and we ARE all about customer satisfaction.

    I think it is important to note that, as most of us know, compliant pin
technology is not designed to be soldered.  All pressfit connections are not
compliant - some pressfit connections are designed with retention features
that are there only to enable a good soldered connection. Connections
designed for compliant pins which have proper drilled hole size, and proper
plating should never have to be soldered.  It's when these factors are not
met that suppliers and customers have to discuss either scrapping the board
or soldering the compliant connections and accept the risks associated with
that decision. After having spent many years working for the worlds's
largest connector manufacturer, I never heard of a failure caused by an
"unsoldered" compliant! pin.
