We are using a connector from ITT-Cannon with part number
167000-0234. This is a four leaded PCMCIA plastic connector with Tin/Lead
termination finish on the leads. The problem we have is that the connector
pops off from the board when a very slight force is used, measured is
around one pound, this problem is detected at systems test when plugging
the female connector to initiate the functionally test of the product. We
already checked the oven profile, X-ray the components, measured the
Tin/Lead termination finish thickness and everything seems to be alright.
This is the first time we use this type of connector, before we had
metallic PCMCIA connectors that have big leads on the sides to help the
strength of attachment and  did not have any issues. This current connector
we are using is all plastic with two plastic tabs for alignment, with just
the four leads to hold it. Is anyone using a connector like this?, What
would be the mechanical strength of a solder joint when pull test is
performed?


          Any comment would be appreciated
