The IPC/EPA Design for the Environment (DFE) Making Holes Conductive (MHC) 
Project is presenting results of the MHC Cleaner Technologies Substitutes 
Assessment (CTSA) in a series of free seminars across the country this year.

As part of the DFE MHC project, the performance of seven MHC technologies 
was tested in real PWB facilities.  These seven technologies were as follows:

*  traditional electroless	*  non-formaldehyde electroless
*  carbon			*  graphite
*  palladium			*  conductive polymer
*  conductive ink

These technologies were evaluated in the DFE MHC CTSA for health and 
environmental risks, technical performance, costs, and implementation.  
The results will be presented in a series of free seminars sponsored by 
IPC, the EPA, and various regional circuit associations.

The dates and locations for these seminars are as follows:

May 15		Best Western Serville	Bloomington, MN

May 21		Best Western Midway	Elk Grove Village, IL

September 10	Radisson Hotel		Chelmsford, MA

October 6	Hyatt Crystal City	Arlington, VA

November 13	Best Western Airport	Phoenix, AZ

Ten DFE PWB project documents will be provided to all seminar attendees, 
including five pollution prevention case studies and a paper on 
implementing MHC technologies.
