Subject: [TN] ASSY: Conformal Coating Performance
The following message is posted at the request of the leaders of the IPC
Cleaning and
Coating Committee:
Recently there have been several questions on actual long term field
performance of
conformal coatings based on several anecdotal observations. There are
numerous
specifications and standards that address conformal coating material
performance/qualification, design and application requirements.
However, very little
documented correlation exists between design requirements and actual
long term performance under field conditions. In addition, standard
communication of
design requirements related to conformal coating and what performance
should
reasonably be expected from a conformal coating (i.e., the myth that
conformal
coatings are impervious to water/water vapor, etc.) does not appear to
be clearly
and/or readily recognize in the industry.
IPC and the Cleaning and Coating Committee are considering holding a
forum/panel
discussion on the above issues at the fall IPC committee meetings to be
held as part
of IPC/SMTA Electronics Assembly Expo in Providence, RI October 24-29.
Several users
and customers (FAA, etc.) have expressed interest in such a forum. The
objective
would be to have a short presentation from conformal coating users, FAA,
material
suppliers, etc., addressing the above issues and any data supporting
recommendations
whether or not further work should be pursed by IPC membership in this
area.
Here's where we need your help! We're trying to determine if there is a
significant
interest from IPC members and other users to support holding such a
discussion in
Providence.
If your believe the subject is of sufficient interest and would consider
attending an
open panel discussion, audience question and answer session on this
subject, please
contact Jack Crawford a the IPC ([log in to unmask]) by 28 August to
indicate your
level of interest. We will use the results of this poll to determine if
such a
session should be organized.
