I am also very interested in this topic, also for Hybris and PCB's... If anyone has info, please respond to the group. Thanks, Michael Lang [log in to unmask] ---------- Does anyone have any information on the effect of no clean residues on RF. I am interested at what frequency interference begins (if any) and what type of device you are talking about ie. phine, radio etc.. I am interested in both PCB and Hybrid Thick Film (alumnia) applications. Also, is anyone using no cleans in the Gigahertz level - if so what level? *************************************************************************** * 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] * ***************************************************************************
