We are currently using a green-colored 6 mil transparent "mylar" to inspect for missing and mislocated holes. It appears that when we drill this with panels (same stack)it is melting and leaving unremovable debris in the holes. Any suggestions on a different material or different technique? *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * ***************************************************************************
