EA Activated Hydrogen Technology Enables Fluxless Die Attach with Zero to
Near-Zero Voids
LEHIGH VALLEY, Pa.,  Feb. 11, 2013  /PRNewswire/ -- Air Products (NYSE: APD)
will highlight advances in its proprietary electron attachment (EA) technology
for soldering applications at the IPC APEX Expo in  San Diego, Calif., from 
February 19-21. IPC APEX attendees can stop by Air Products Booth #2708 to learn
about the advantages of EA activated hydrogen over plasma-based and flux-based
processes for cleaning soldering surfaces during electronics assembly and
packaging. These advantages include improved solder wetting, lower reflow
temperature, decreased overall voiding tendency, and no flux residue-related

In addition, Dr.  Christine Dong, lead research scientist for merchant gases
technology at Air Products, will present the results of a study on EA technology
titled "Fluxless Die Attach by Activated Forming Gas." The study demonstrates
that it is possible to achieve a high-quality die attach with zero or near-zero
voids by using EA. Dr. Dong's presentation is part of the  Novel Attachment
Technologies and Processes  (S34) conference paper session to be held on 
Thursday, February 21, from  10:15 AM to 12:00 PM. IPC APEX attendees can 
register  to learn how EA-activated forming gas can effectively clean soldering
surfaces during fluxless die attach, bringing numerous advantages compared with
conventional flux-based processes.  

Air Products representatives will be available at the booth to speak with IPC
APEX attendees about the company's complete range of  application technologies
and solutions  that can help electronics packaging and assembly customers
improve productivity and optimize their total cost of ownership. Among these
solutions are the use of nitrogen reflow for Head-in-Pillow defect reduction and
 Air Products Inert Wave Soldering  technology, which has helped an electronics
contract assembly company reduce wave solder defects by 90%, enabling them to
achieve improved production efficiencies and cost savings.
