Fellow
designers;
I recently talked to
EIA concerning component land pattern naming schemes, and
the
lack of them. With
the introduction of PLCCs and SMT ICs, there has been good work
done with land
pattern names. No matter the package or part number we are able
to
determine and select
the land pattern in accordance with the land pattern name.
One of the large
obstacles in out industry is the lack of generic patterns and
naming
schemes that
we may use to identify generic parts. I.E. Resistors, caps, etc.
I am asking
for your support and solidarity in the inception of common pattern
naming
schemes. In
the next few months, (April I believe) EIA representatives will be
meeting
with the major
electronic manufacturers for an annual meeting.
This will seem
like a very minor problem to the manufacturers and one that isn't
worth
editing/changing data sheets to accommodate, but this
problem has caused so much
confusion and
problems in our industry for countless years, that it is about time it
was
cured.
Many of you
are seasoned professionals that no longer see this as a problem
because
you now have a
scheme or a routine, and aren't as concerned. For new designers
and
startup
companies this is a large concern. It causes custom library names and
internal
part numbers
that cause the same amount of problems as the original
problems.
I'm not asking
that you expend your time but asking for your support. IPC is not
responsible
nor tasked
with developing these schemes, but rather consolidating and
documenting
these
names.
EIA and their
counterparts aren't particularly responsible for this either, but group
known
as ECA
(Electronics Components Admin.) in conjunction with component
manufacturers
are the only
ones that are capable of making this standard and implementing
it.
All the names
and schemes in the world are nothing without component
manufacturers
support.
I will, at a
later time, provide names and email addresses that you may send a note of
your
support to, as
well as manufacturers, to support and embrace such a
change.
This would
cause the manufacturer to provide a name with every component that would
correlate
to a
particular pattern. We will no longer have to save patterns has cryptic names
but as a pattern.
No longer
would we have several manufacturer part numbers for the same pattern, but one
unified
pattern
name.
I thank you
for your time, and ask this of you, not for me, but for our
industry.
Thank you and
God bless....
