Presented by: Doug Pauls, Rockwell Collins

Conformal coatings should be chosen based upon how well they protect the electronic circuit against the challenges of the end use environment. The difficulty is that not many people know how to make that evaluation. What kinds of tests can be used? What parameters should be chosen? How should the data be interpreted? This course covers various tests that are used to do base material characterizations, as well as tests which cover more functional aspects of conformal coating. While much of the testing will be from a Class 3 Avionics perspective, the methodologies covered can be extended to other industry segments.
Course Outline:
Uses of conformal coatings
Materials characterization tests for coatings
Performance specifications for coatings
End Use Environments Overview
Testing of Conformal Coatings
Fluid Susceptibility
Fungus resistance
Salt spray and salt fog
Sand and dust testing
Humidity testing – static and condensing
Waterproofness testing
Thermal cycling and thermal shock
Heat flow
RF testing
Material compatibility
Process effects
What defects are found in these tests and what they mean
Illustrative Case Studies
Question and Answer Session
Who should attend:
This course is written for individuals responsible for choosing or evaluating conformal coatings for use on electronic assemblies in harsh end use environments.

Your Instructor:
The instructor for the course is Doug Pauls, a Principal Materials and Process Engineer at Rockwell Collins, Cedar Rapids, IA. Doug is the Chairman of the IPC Cleaning and Coating committees.

Doug holds a B.A. in Chemistry and Physics from Carthage College, Kenosha, Wisconsin, and a B.S. in Electrical Engineering from the University of Wisconsin, Madison. He worked for the Naval Avionics Center in Indianapolis, Indiana for nine years as a Materials Engineer. Doug spent 8 years as the Technical Director of Contamination Studies Laboratories, performing process troubleshooting and optimization from a residue analysis perspective. Doug is an active IPC Chairman (General Chairman – Cleaning and Coating, Bare Board Cleanliness, Solder Mask) and presently chairs the IPC Technical Activities Executive Committee. Doug is most notably known for his expertise in surface insulation resistance testing, cleaning and cleanliness assessment, conformal coatings, and how to qualify manufacturing processes. Doug moved to Rockwell Collins in 2000, serving as their corporate expert on conformal coating materials and processes. He received Rockwell’s Arthur A. Collins Engineer of the Year award in 2004.

Doug is known to have a pathological fear of free time, has been happily married for 28 years. He has 3 children and so has little free time, but does some woodworking, woodcarving, and occasionally sneaks away to do some hunting and fishing.
