We are using press fit connector for some time without any particular visible problems, but still we need some kind of workmanship standard as a general guideline of what is wrong, acceptable and preferred levels for this job. Can someone direct me where can I find it or send me a copy.

Thanks, Michael

First thing I'd use is IPC-A-610C, �4.8.2 Connector Pins - Press-Fit Pins. Does it work in your case?

Thanks for your quick respond. I'm looking for some more detailed specs. Like: pressure force, the "do" and "do not do" rules for the connector itself (include the plastic housing), tools etc.

Regards, Michael

you can use IPC and Compact PCI standards for guideline then it depends on what kind of connector you want to pressfit. each supplier has its own design on pressfit pins like "needle eye", "baby H" etc... It is also importand to use proper equipement and machinary. manual, pnuematic or electrical press machine! the easiest and best way is that you follow supplier's spec and rekommandations.

you should be able to get the force requirements from the connector manufacturer. Both the minimum and maximum forces used in the pressing cycle should be recorded to know the connector is properly seated without excessive force that can damage the connector and shorten its life. Take a look at this site http://www.goasg.com and you'll have a better idea about forces and standards.
