Joyce,
Thanks. I thought you were referring to insertion force per pin which I thought was a little low for inserting press pin connectors.
Sorry for the confusion.

The force per pin to insert nickel-gold is higher than solder coated, but it is manageable with today's insertion equipment, not arbor presses and flat rock tooling like I had to use eons ago. The nickel-gold pins have to be inserted at a lower rate than solder coated, but otherwise work well.

I've never heard of this and I was wondering if there is any quality/reliability data in the industry as to why one should/shouldn't do this. Our customer's explanation was that it would add mechanical integrity to the joints. Thanks in advance.
