Hello All,

I am working with a customer to determine the optimal finished hole diameter
for press-fit connectors into a Gold finish PCB. The supplier's data sheet
for the connector specifies .024"+/-.002" HASL plated holes. We have learned
from experience that the connector insertion success rate is greatly
improved when using a slightly larger hole on a gold finish PCB since it is
less compliant with the connector pins than the soft HASL.

So far, the supplier has not given a recommendation on a diameter for gold,
so I am looking for other industry standards to validate our findings.

Any ideas would be greatly appreciated.

Thanks, Dave
