Beyond the Rulebook
What happens when the rule book is no longer useful, or worse, was never written in the first place? In today’s fast-moving electronics landscape, we’re increasingly asked to design and build what has no precedent, no proven path, and no tidy checklist to follow. This is where “Design for Invention” begins.
March Madness
From the growing role of AI in design tools to the challenge of managing cumulative tolerances, these articles in this issue examine the technical details, design choices, and manufacturing considerations that determine whether a board works as intended.
Looking Forward to APEX EXPO 2026
I-Connect007 Magazine previews APEX EXPO 2026, covering everything from the show floor to the technical conference. For PCB designers, we move past the dreaded auto-router and spotlight AI design tools that actually matter.

Rogers Introduces RO4450T Glass Reinforced Thermoset Multi-Thickness Bondply
August 31, 2020 | Rogers CorporationEstimated reading time: 1 minute
Wireless circuit designers can now enjoy a true breakthrough with Rogers Corporation's RO4450T™ bondply. This product offers designers a spread glass reinforced bonding material in seven thickness options ranging between 0.0025” (0.064mm) and 0.006” (0.152mm), greatly improving flexibility for high multilayer board count designs.
RO4450T glass reinforced thermoset bondplies were developed for wireless circuit designers looking for a better performing and more reliable alternative to FR-4 materials. The thermosetting hydrocarbon ceramic resin system facilitates a high post cure Tg, making these materials an excellent choice for multilayers requiring sequential laminations as fully cured RO4400 bondplys are capable of handling multiple lamination cycles.
In addition, FR-4 compatible bond requirements permit RO4450T bondply and low flow FR-4 bondply to be combined into non-homogeneous multilayer constructions using a single bond cycle. RO4450T bondplys are recognized by Underwriter Laboratories with the UL 94 V-0 flame rating, and are compatible with lead-free processes.

Rethinking Reinforcement Materials for Advanced Packaging
05/14/2026 | Ivana Ivanovic-Hesselink, Flexiramics B.V.Materials that once quietly supported the industry are now becoming limiting factors. The electronics industry is experiencing unprecedented pressure as RF systems push into mmWave frequencies, high-speed digital architectures advance into their next performance generation, and power densities climb across automotive, telecom, aerospace, and computing. Reinforcement materials, long treated as a background detail in laminate design, are suddenly at the centre of performance, reliability, and supply‑chain discussions.
Rethinking Stackup, Materials, and Tolerances in Modern Designs
05/14/2026 | Kristin Moyer, Global Electronics AssociationThe simple rectangular rigid PCB is becoming increasingly infrequent. This reality necessitates designing with concepts well outside traditional rigid PCB methodologies. For example, the designer of wearable electronics may need to implement conductive fibers integrated into the textile material. Heads-up displays, like those in VR/AR headsets and glasses, require transparent circuitry etched into the display glass. The process of designing without a rule book usually starts with something other than the traditional board design process.
