Why not let those who have been contributing to IPC specifications for more than 25 years
help you with qualification, acceptance and conformance of your products and surveillance
of your Preferred Supplier List (PSL)?
Trace welcomes new IPC President, John Mitchell
Debora Obitz (27-year
year IPC Member) and John Mitchell at IPC Midwest
Debora was recognized for her contribution to IPC

2012 Renee
Michalkiewicz (17-year
year IPC member), John Radman (23
year IPC member), Keith Sellers (2-year
member) and Debora Obitz (27-year
year IPC member) share their thoughts.
D-31b (IPC-2221 Printed Board Design
Design) – The new revision is complete and pending consensus vote. The
110 coupon committee requested that the critical comments, that were previously reviewed and discussed, are
included such as the location of the registration coupon.
D-55 (Embedded
Embedded Devices Process Implementation Subcommittee
Subcommittee) – The meeting centered on establishing
the committee’s KAVI website.

3-11: (IPC-4101
4101 Laminate/Prepreg Materials Subcommittee) – The major discussion focused on the UL
classification of FR-4 laminate. The
he UL STP vote for a one bucket and four bucket systems
system failed to pass.
Neither proposal can be voted on again. Tony Senese from Panasonic, the group’s chair, suggested that the IPC
Laminate and Prepreg Subcommittee propose a new system for Re
Re-Classifying FR-4. The
T new system would
consist of two buckets each with its own MCIL program - one brominated and one halogen-free.
There would
still be an “all other” group for CCL that do not fit either of the MCIL buckets. These would require testing.
This proposal was well received by the group
group, and a proposal will be presented to UL.
Renee Michalkiewicz (Top row, 4th from the right) was recognized for her contribution to IPC J-STD-002D
14: (Plating Processes Subcommittee) – Discussions involved revisions to the following specifications, IPC
ENEPIG-4556 and IPC ENIG 4552.. Comments were reviewed, appendices were discussed and actions
4-33a (Low-Halogen
Halogen Guideline Task Group IPC-4903) - The
he meeting was focused on the
t discussion and
debate of 100+ comments to the revision of IPC
IPC-4903 “Guideline for Defining ‘Low-Halogen’
Halogen’ Electronic
5-23a (IPC/J-STD-003 PCB Solderability) – There was a request to reinstate the edge dip and solder float test
until replacements
ts tests are available. The industry needs methods to use to determine acceptability. Gerard
O’Brien was reluctant to do this since it apparently had been voted in the task group to delete those methods
since they are not representative of what a PB actu
ally sees during soldering. The durability categories were
removed from the specification.

5-23b (IPC/J-STD-002 Component Solderability) – The J-002
002 revision D is completed and barring any
negative votes will be released. There was discussion concerning the round robin test on the solder paste
aperture for Test Method S.
5-24a: (IPC J-STD-004
004 Flux Specifications Task Group) – Renee Michalkiewicz
alkiewicz is the chair of this
committee and the vice chair of the Assembly and Joining Committee. We are beginning the process of
reviewing all of the J-STD-004
004 test methods. Five round robins will take place between Midwest and APEX.
5-24b: (IPC J-STD-005
005 Solder Paste Task Group) – We began reviewing some of the test methods that are
called out in J-STD-005.
005. Viscosity testing of paste was discussed and some initial studies were scheduled to
see if a small variation in temperature affects viscosit
viscosity results.
5-24c (Solder Alloy Task Group) - The discussion focused on comments to the revision of J-STD-006
as well
as to IPC-TM-650, method 2.4.48.
5-32a (Ion
Ion Chromatography/Ionic Conductivity Task Group
Group) – All cleanliness methods are currently up-toup
ate. John Radman, the chair of this group, opened discussion on the possibility of developing a method for
component cleanliness testing. Method could possibly support counterfeit component testing. A draft method
will be distributed to the group.
5-32b (SIR and Electrochemical Migration Task Group) – Keith Sellers is the chair of this task group.
Revisions to the IPC-B-52
52 test board were reviewed, based on comments given at IPC APEX in Feb. These
revisions are focusing on the addition of “other” patte
patterns to the board – as possibly the start of an IPC SIR test
pattern library. Additionally,
dditionally, the use of underfills with the IPC
52 test board was discussed. Doug Pauls
from Rockwell Collins presented data that he had obtained based on internal studies pe
rformed at this company.
Rich Kraszewski from Plexus gave a short presentation on an ECM topic that HDPUG has been discussing.
5-33a (IPC-CC-830
830 Conformal Coating
Coating) – This group will be doing a new revision for this document. So far
there are two big debates
ates in this committee:
• Trying to find an acceptable adhesion test for coatings. Many users are requesting this as an incoming
inspection test. Several tests have been discussed: cross hatch (we deleted this from the earlier
revisions since it was not repeatable and had variable results across testers), tape test – there are 2 brands
of 600 tape (office use and industry strength) each will give different results and the tape will not adhere
to silicones, and scratch tests in ASTM – this test is not effective for silicones.
• MIR values that were changed from 500 to 5000 with no gage R&R to back up the change. It is
believed that when the document was mimicking the MIL
46058 (military document that was
scheduled 10+ years ago for cancellation) it was cha
nged at that point. However, it was not taken into
consideration that the coupons used are different in spacing, thickness, and widths. They are checking
into the correlation of the D and C patterns. This has been a recent discovery since there are more
companies requesting testing to IPC
IPC-CC-830 as of late. Testing to the CC-830,
830, at least in my

observation, was minimal since we had the “Grandfather clause which states if you are qualified to the
46058 you are automatically qualified to the IPC
830. Most tested to the military document
and therefore met the IPC document.
5-33c (IPC-HDBK-830 Conformal Coating Handbook) – There are 45 of the 47 topics completed in this
document. Six chapters were previously reviewed and chapters 2, 8, and 9 were reviewed in the last session.
Chapters 3 and 4 were reviewed during this meeting and minor changes were made.
5-33f (Potting & Encapsulation) – We celebrated the release of the handbook.
7-11: (IPC-TM-650
650 Test Methods Subcommittee) – Renee Michalkiewicz
icz is the chair of the general
committee. The discussions focused on the newly published IPC
650 MDP (Method Development Packet).
We discussed what data would be acceptable for method verification studies. Additionally, discussions
continued on whether
her IPC could be successful at beginning a laboratory proficiency program.
7-24 (Printed Board Process Effects) – We reviewed each section of the document and received a few
manufacturing and supplier volunteers. This document is set to outline issues with manufacturing boards
(Example: separation at the interconnect), and it will show a photograph and list all ooff the possible causes for
the defect. Trace volunteered to supply photographs of defects.
IPC-6012 and IPC-A-600) – Debora Obitz is the vice-chair
of the general
7-31a/D-33a (Joint meeting of the IPC
committee. Discussion revolved around the reduction in traces
ces with Leo Lambert from the 610 group. The 610
group was concerned that since we give a reduction (20
30%) due to defects (drill splay, nicks, scratches,
mouse bites, etc) that IPC-A-610
610 in turn gives an additional reduction of 20% - it was discussed and
an stated that
the additional reduction cannot be conjoined with any reduction in the original trace. There was discussion
concerning the new coupons designed for registration testing and additional discussion on cleanliness testing.
