Scott, Sorry, I don't even remember getting your first message. In a previous life as a mass laminator we used rivets to hold two inner layer cores together. Tooling holes had been precisly punched and we sandwhiched the inner cores around pre preg. It worked pretty well. Problems we encountered had to do with listing or breaking. We use a two piece rivet sized for the package they had to hold. Good luck.

In a hope to get some information I would like to resubmit my inquiry and this time ask more direct questions. What height of rivet, before riveting, do most people use for panels that are 0.018" to 0.062"? Can you use the same rivet for the different thickness? What height should the rivet be after riveting the panels? What type of gap do you set on your rivet machines? Do you use different gap settings for different thickness' of panels? Any suggestions or answers would be appreciated. *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To subscribe/unsubscribe send a message <to: [log in to unmask]> * * with <subject: subscribe/unsubscribe> and no text in the body. * *************************************************************************** * If you are having a problem with the IPC TechNet forum please contact * * Dmitriy Sklyar at 847-509-9700 ext. 311 or email at [log in to unmask] * *************************************************************************** *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To subscribe/unsubscribe send a message <to: [log in to unmask]> * * with <subject: subscribe/unsubscribe> and no text in the body. * *************************************************************************** * If you are having a problem with the IPC TechNet forum please contact * * Dmitriy Sklyar at 847-509-9700 ext. 311 or email at [log in to unmask] * ***************************************************************************
