Dm will not make a difference - actually if drilling is still primary cause - will be the same or worse - since Dm is thinner coating. A reduced oxide layer can eliviate problem to a certain degree - but then - reduced oxide brings in a problem of it's own. regards Richard Fudalewski Atotech Canada *************************************************************************** * 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] * ***************************************************************************
