Abstract:
The purpose of this two part
presentation is to give some history and insight into EMC Component Specifications
and some essential EMC module design practices.
Part 1 addresses automotive
component EMC specifications. The
responsibility for meeting these requirements is usually the Product Design
(PD) Engineer. Although it is admirable
for the EMC community to try and do the best job possible, it has a tendency to
go to extremes regarding testing requirements/limits. Such EMC groups are
typically a separate community and have a narrow view. This may be in conflict with some of the
realities of the PD engineer - minimal staffing, keep to schedule, keep costs
down (weigh cost/benefit), make a profit.
These specs have evolved over many
years, starting at a time when EMC was not well understood and design practices
were not in place. For many present day
EMC practitioners, this history is not known so it makes it difficult to know
when to “Hold or Fold” when a test anomaly is observed. Different people looking at the same data can
come up with quite different conclusions depending on their background, insight
and flexibility. Specific test examples will be presented to illustrate this.
Test
methods have many limitations and compromises - simple pass-fail criteria
results in too much non value work (test issues that are not real world
concerns) especially for modules that follow basic EMC design rules. EMC testing is usually lengthy and expensive and diverts
from time to “sand box” where real issues are found. The process should be design guidelines
implementation and development testing followed up by design verification with
realistic limits. The main goal is to minimize field issues not just
pass specs.
The EMC process has potential to be
improved and simplified but due to the large EMC infrastructure (OEM/Vendor EMC
staff, Testing facilities/staff, Equipment vendors, Regulators and regulations,
EMC committees) it is extremely difficult to change. Even so, certain practices can be implemented
to improve the process (e.g. more realistic acceptance criteria and data
analysis).
Part 2 gives some specific module
design rules along with actual illustrative examples. To design a product that meets the severe
automotive EMC requirements can seem overwhelming. Although it is possible to try and apply the
many design rules that are well publicized, there are only a relative few that
really make a difference

Biography:
Mr. Nielsen retired from
Visteon-Ford in 2005 with over 35 years experience in a number of
disciplines. After college, he served in
the US Navy submarine service after which he was an instrumentation engineer at
the Chrysler Corp Proving Grounds for 3 years.
He then started his career at the Ford Motor Company crash test facility
as an instrumentation engineer. Arnie then spent 10 years as a Product Design engineer in powertrain electronics (engine-transmission controllers,
actuators, software, etc). For 20 years
he was a Technical Specialist involved in the design and testing of most
automotive electronic products and the development & implementation of a comprehensive
EMC design and test process. He has also
been deeply involved in Reliability and Product Assurance. He has a working knowledge of many
environmental specs including Ford, Mazda, GM, BMW,
Since retiring, Mr. Nielsen has been
actively consulting on electronic design and EMC for over 20 companies
(including electric vehicles).
Mr. Nielsen has a BSEE from
