TechNet: We have been experiencing some registration problems lately, and I was wondering if anyone is aware of a software program that can help in determining inner-layer scaling factors. I was told that there may be such a program available. It supposedly takes into account copper weight, copper area per side, core thickness, and overall board construction to calculate scaling factors for the various core thicknesses within the MLB. Any input on this, including other methods of calculating scaling factors, would be appreciated. Thanks, John Lennox Process Engineer EMC *************************************************************************** * 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] * ***************************************************************************
