The D-31b IPC-2221/2222 Task Group met to advance the working draft of IPC-2226A, Sectional Design Standard for HDI Printed Boards, which is the first revision effort for this standard since its original 2003 publication. Attendees were segmented into five subgroups to work on content in sections 3 through 6.
The D-33a Rigid Printed Board Performance Task Group and the 7-31a IPC-A-600 Task Group met jointly to review and approve photographs of acceptable and nonconforming anomalies for the future “J” revision to IPC-A-600, Acceptability of Printed Boards. The photographs presented were intended to address new and expanded requirements released in the new IPC-6012D, Qualification and Performance Specification for Rigid Printed Boards.
The D-35 Printed Board Storage and Handling Subcommittee met to complete the review of industry feedback to the working draft of an “A” revision to the IPC-1601, Printed Board Handling and Storage Guidelines. The group addressed comments related to measurement of moisture content, the use of oxidation arrest paper, the impact of baking on ENEPIG and ENIG surface finishes, and recommendations for resealing opened moisture barrier bags for storage of bare printed boards. A Final Draft for Industry Review will be circulated in Q4 2015.

Mastering PCB Floor Planning
08/28/2025 | Stephen V. Chavez, Siemens EDAPlacement of PCB components is far more than just fitting components onto a board. It’s a strategic and critical foundational step, often called “floor planning,” that profoundly impacts the board’s performance, reliability, manufacturability, and cost. Floor planning ties into the solvability perspective, with performance and manufacturability being the other two competing perspectives for addressing and achieving success in PCB design.
Elementary Mr. Watson: Routing Hunger Games—May the Traces Be Ever in Your Favor
08/26/2025 | John Watson -- Column: Elementary, Mr. WatsonI’d like to share a harsh truth, and I say this as a friend: PCB designers are often their own worst enemy. It’s rarely the complexity of the circuit, the last-minute changes from mechanical, the limited enclosure space, or the ever-expanding list of design rules that send projects to the dust heap of failed boards. More often, it's our own decisions, made too quickly and narrowly, and with too little foresight, that sabotage an otherwise good design.
Target Condition: Floor Planning Without a Floor
08/27/2025 | Kelly Dack -- Column: Target ConditionBy a show of hands, how many PCB designers have been asked to start a layout without a board outline, keep-out zones, or even height constraints? How many have had to work within a specific enclosure before the schematic was finalized? If this sounds familiar, you're not alone. Starting a PCB layout without critical constraints is like hiring an interior designer to buy furniture and carpet for a house you haven’t even purchased yet, or, even worse, trying to fit four bedrooms' worth of furniture in a one-room cabin.
I-Connect007 Editor's Choice: Five Must-Reads for the Week
08/22/2025 | Andy Shaughnessy, I-Connect007In this week’s roundup, we have a variety of articles covering design, manufacturing, sustainability, and, of course, tariff negotiations. We have a milestone anniversary to celebrate as well, with Dan Beaulieu about to publish his 1,000th column. When does Dan even sleep? Here’s to hoping that we have 1,000 more weeks of "It’s Only Common Sense."
