We define the hole size of .042 to .037 and do not have any problems 
pressing the compliant pins for military connectors and pins and also VME 
type connectors.  Most connector specifications allow up to .043 but we have 
had problems with ES testing.  Most board fabricators can work with a .005 
inch hole size range.

You may also want to check alignment of the press fixture and other setup 
parameters.

Hey Folks,
Is anyone having problems with pins bending during the insertion of
     compliant press-fit connectors?

     In an effort to have a product which was 100% surface mount, we chose
     the compliant press-fit pin backplane connector so that wavesoldering
     would not be necessary.

     Since then, manufacturing had problems with pins bending during
     insertion, so we reverted to solder pins and wavesoldering.

     Now, to eliminate the wavesoldering process thereby saving time and
     money, the press-fit pin is being considered once again.

     If you've had any types of problems with press-fit connectors, what
     were they and how did you resolve them?
Thanks in advance
