OCTOBER 2020 I DESIGN007 MAGAZINE 99 5 Tim's Takeaways: Thermal Management for PCB Designers— Staying Out of the Fire E If there's one thing in life that really feels the pressure of being in the hot seat, it's the PCBs that we design. But PCB designers often feel a lot of pressure while doing their work, which puts them squarely in the hot seat. Tim Haag shares four techniques in thermal management for PCB designers. 6 Dana on Data: A Team Method to Reduce Fabricator Engineering Questions E Hundreds of PCB designs are released to be quoted or fab- ricated every day around the world, and most will have engi- neering questions or technical queries generated once the data package has been received and analyzed. Dana Korf outlines seven fundamental steps based on Lean/Six Sigma concepts to reduce data transfer issues. 7 The Bare (Board) Truth: 5 Questions About Improving Thermal Management E Mark Thompson from Monsoon Solutions answers five ques- tions about thermal manage- ment at the design and PCB lev- els, including how much heat a via dissipates, how to identify potential thermal issues, and more. 8 Mentor and Z-zero Collaborate on New Stackup Tool E I recently spoke with Max Clark, business unit manager with Mentor, a Siemens Business, and Z-zero founder Bill Hargin about the newly formed part- nership that resulted in a new stackup tool that Mentor is now selling world- wide. Fun fact: Hargin used to work for Mentor as part of the HyperLynx team, which now has an interface with Z-planner Enterprise. 9 This Month in Design007 Magazine: Thermal Fundamentals With Mike Jouppi E The I-Connect007 team recently interviewed Mike Jouppi, one of the champions of thermal man- agement in PCBs. Mike spent decades working on updating the old IPC current-carrying data, which dated back to the 1950s, and he is the primary architect behind IPC-2152— the standard for determining current-carrying capacity in printed board design. J Quiet Power: Be Aware of Default Values in Circuit Simulators E Simulators are very convenient for getting quick answers with- out lengthy, expensive, and time-consuming measurements. Istvan Novak explains how, sometimes, you can be surprised if you forget about the numerical limits and the limitations imposed by internal default values. for the latest circuit design news and information. focuses on the rapidly growing flexible and rigid-flex circuit market.
