Hello, We are having problems with our paste tack time not lasting as long this time of year. We are running at 14% humidity now, normal is about 40% to 50%. We are using a water soluble paste, 90% metal content, with a quoted tack time of 6 hours on stencil, and 6 hours on board. We are seeing problems after 3 to 4 hours. Does anyone have experience to say this is normal for the humidity, or ideas as to what we could be doing wrong.(I know of plenty myself, but still would appreciate more). Thanks Steve Quinn Heurikon Corp *************************************************************************** * 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] * ***************************************************************************
