Materials Committees Report Cool Progress from Sunny Phoenix

IPC Director of PCB Programs, Standards and Technology Tom Newton reports on his January standards meetings: 

The 3-12a Metallic Foil Task Group met on Monday, Jan. 11. The group heavily modified a proposed optical test method as used by Gould  Electronics in their German research facility.  This modified document  in Track Changes format is now posted in the 3-12a Task Group Home Page; Drafts section.  This version and other non-contact test methods will be explored and consolidated at the upcoming D-15 Subcommittee meeting  at IPC APEX EXPO 2010.

The D-13 Flexible Circuits Base Materials Subcommittee resolved a single negative vote from the Ballot on IPC-4202A, Flexible Base Dielectrics for Use in Flexible Printed Circuitry.  Accordingly, a second or negative vote esolution Ballot is in progress which means the IPC-4202A should be released prior to IPC APEX EXPO 2010.  The subcommittee immediately turned its attention to the IPC-4204A draft  to advance it closer to its release later this year.

Members of the D-13b Flexible Circuits Covercoat Materials and the leadership of the 5-33b Soldermask Performance Task Groups jointly met on Wednesday (Jan. 13) .  These groups advanced all the proposed  changes as recommended by the flexible circuits D-13b Task Group to the next Draft 5 of IPC-SM-840E,  Qualification and Performance Specification of Permanent Solder Mask.  The next step is for members of the D-13b Task Group to join the 5-33b Soldermask Performance Task Group meeting on Wednesday, April 7 at IPC APEX EXPO 2010 to advance the E revision of the SM-840 document to its release. 

The D-15 Flexible Circuits Test Methods Subcommittee met on Tuesday, Jan. 12, and generated a potential Final Draft of the test method for measuring the service temperature of flexible printed circuitry.  Another teleconference of the D-15 Subcommittee will be held in late January to change the “potential” Final Draft to Final Draft for presentation to the 7-11 Test Methods Subcommittee for ultimate insertion as the A revision of TM 2.6.21 into the IPC-TM-650 manual.

    It took lots of diligent work from a committed subcommittee to get Service Temperature to this final draft. Thanks to all who hung in there.
    Get ready for the review at the Las Vegas show.
    Rocky, co-chairman, D-15.
