Good press fit is max 10g. Anything beyond are living dangerously.

Product that are built around function alone have not been designed at all, but merely engineered. -prof. Ashby

Hi Steve,

As Mr. Stadem explained, soldering a press pin connector defeats one of the big advantages for press pin connectors.

The input that nickel-gold press pins don't work is not entirely true. 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.

Most importantly for you, what does the connector manufacturer's specifications state and what are their manufactuirng recommendations?

Beware of press pin connector manufacturers who cannot provide those details for you.

I smell a waiver coming up for you if you can gather all the facts.

Hang in there and best of luck,

Gerry Gagnon

>     I have a customer who is specifying a press fit connector to be soldered after the press fit operation. 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.
