The Standards of Design
Our expert contributors discuss how PCB designers can utilize standards to save time and money, not to mention frustration. We also spotlight the newly updated version of the IPC Checklist, a handy guide that illustrates which standards cover which topics, from front-end design through assembly.
Rigid-flex: Designing in 3D
In this month’s issue, our expert contributors share their best tips, tricks and techniques for designing rigid-flex circuits. If you’re a rigid board designer considering moving into the 3D world of rigid-flex, this issue is just what the doctor ordered!

New Book From Isola Highlights Importance of Material SelectionJanuary 14, 2022 | I-Connect007 Editorial Team
Estimated reading time: 1 minute
In The Printed Circuit Designer’s Guide to... High Performance Materials, the latest release from I-007eBooks, readers will learn how to overcome challenges associated with choosing the right material for their specific application. Author Michael Gay of Isola provides a clearer picture of what to know when determining which material is the most desirable for which products.
Key questions answered:
- Why is PPO resin better than epoxy resin for electrical performance?
- Why could flat glass fabrics reduce the skew and ease for laser drilling?
- Why is very low-profile copper foil preferred for high-speed applications?
- What is the impact of raw materials on data rate and signal integrity testing?
PCB materials and DFM expert Mark Thompson says, “I love this book, particularly the sections on the effects of the glass weave, the history of laminate, and the difference between Dk and effective Dk. I highly recommend it for any designer or engineer looking to better understand laminate.”

The topic of intrinsic copper structure has been largely neglected in discussions regarding the PCB fabrication quality control process. At face value, this seems especially strange considering that copper has been the primary conductor in all wiring boards and substrates since they were first invented. IPC and other standards almost exclusively address copper thickness with some mild attention being paid to surface structure for signal loss-mitigation/coarse properties.
At PCB West, I sat down for an interview with John Andresakis, the director of business development for Quantic Ohmega. I asked John to update us on the company’s newest materials, trends in advanced materials, and the integration of Ticer Technologies, which Quantic acquired in 2021. As John explains, much of the excitement in materials focuses on laminates with lower and lower dielectric constants.
Printed circuit board (PCB) reliability testing is generally performed by exposing the board to various mechanical, electrical, and/or thermal stimuli delineated by IPC standards, and then evaluating any resulting failure modes. Thermal shock testing is one type of reliability test that involves repeatedly exposing the PCB test board to a 288°C pot of molten solder for a specific time (typically 10 seconds) and measuring the number of cycles it takes for a board’s copper layer to separate from the organic dielectric layer. If there is no delamination, fabricators can rest assured that the board will perform within expected temperature tolerances in the real world.
