Well those are some pressing issues that you have, hopefully, accurately gauged. I don't know the end use, but it does take some unique skills to install pins in PWBs. You can be compliant, but not in compliance. Some deformation of the plated through-hole wall and character will lead to better integrity when force is applied in a calculated manner. All holes look and act alike, till you pin one up against the wall. It's like installing septic systems in Arizona; you have to drill some test holes first to demonstrate you have your**** well for those of you who know me I will spare you all the bad puns I could do with this one.

A question for the press fit connector gurus out there. We are looking at a job that uses a couple of 160 pin press fit connectors, and I've never pressed connectors (yet). We aren't going to be building a lot of these, so I'm trying to figure out what the minimal tooling I can get away with would be. I am assuming that I will need: - some support tooling to hold the board and prevent the pressing operation from destroying it. - tooling to hold the connector and distribute the load over the connector - a press - will a manual press do? Assuming the board is properly designed (a fair assumption as it's being produced elsewhere already), is there anything else I need? Is a flat plate with holes matching up with the pin locations sufficient for the base? Thanks, and have a good weekend! regards, Graham Collins Process Engineer, Northrop Grumman Canada Corporation Halifax (902) 873-2000 ext 6215 --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 1.8e To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ----------------------------------------------------- --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 1.8e To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 -----------------------------------------------------
