Giuseppe,
The Amp recommendation is that the hole size after tin lead plating to be
0.56-0.66(.022-.026)   if you are not within that tolerance it may not work.
6.5mm (.2559") is a pretty thick backpanel !  Any way to thin that up a bit?

Subject: [DC] Press-fit holes


Hi all,

we have a backpanel where we use a 68 pins micropress-fit connector (AMP
786555-7). We require a 0.7 +/- 0.025 mm raw hole and a 0.6 +/- 0.05 mm
finished hole.
Because of the board thickness (6.5 mm), our supplier has many problems in
keeping finished hole tolerances. Do you think that increase to 0.75 the raw
hole requirement may be a good solution?



Thank You in advance

Regards

Giuseppe Cannone
