Altium Develop lets your fabricator flag stackup and via problems like these before you release fab data, with design files, comments, and manufacturing feedback in one shared workspace: https://www.altium.com/develop?utm_source=youtube&utm_medium=video&utm_campaign=pcb-layout&utm_content=hdi-pcb-design-review-nrf5340-stackup-microvia-mistakes-to-fix In this HDI PCB design review, Zach Peterson takes a deep dive into a community-submitted nRF5340 audio board with a 0.35 mm pitch wafer-level chip scale package and rebuilds its stackup in the Altium Designer Layer Stack Manager so it can actually be fabricated. You'll see why default 2.8 mil prepreg thicknesses and mechanically drilled via definitions break laser-drilled microvia aspect ratio limits, how to resize dielectrics and drill diameters for 0.75:1 microvias, and how to size a mechanically drilled buried core via without colliding pads inside the BGA. The review also covers HDI trace width and clearance rules, why 1 oz copper won't get you to 2–3 mil traces, stacked versus staggered microvias, and the fabrication drawing mistakes—one drill drawing for six layer spans, missing hole tolerances—that leave your fabricator guessing. If you're routing a fine-pitch BGA or CSP on an HDI PCB, this is the DFM checklist to run before you send files out. 📚 More from this Episode: - Nordic nRF5340 wireless SoC: https://www.nordicsemi.com/Products/nRF5340 Altium Designer Layer Stack Manager documentation: https://www.altium.com/documentation/altium-designer/pcb/defining-layer-stack - Advanced PCB — microvia & HDI fabrication capabilities: https://www.advancedpcb.com/en-us/resources/blog/microvia/ - IPC standards: https://www.ipc.org ( - Selecting the right microvia aspect ratio (Altium Resources): https://resources.altium.com/p/microvia-sizing-your-next-multi-layer-pcb 💡 Watch Next: - HDI PCB Design Review: nRF52840 Via Sizing & Stack-Up Best Practices: https://www.youtube.com/watch?v=MTXhCtOBYWY - Mastering HDI Design Rules in Altium Designer: https://www.youtube.com/watch?v=z6gHXYiVjCw - HDI PCB Stackup Breakdown — Etching Weight, Via Spacing & More: https://www.youtube.com/watch?v=Nmf0GTupQlg - This nRF5340 Board Needs Microvias | 1 Min PCB Design Review: https://youtube.com/shorts/A2Gv1FDATnM 💡 Stay Connected: Don't forget to like, comment, and subscribe for more in-depth tutorials and tips from @AltiumAcademy Share your thoughts and questions in the comments below! 👉 Subscribe for more: https://www.youtube.com/@AltiumAcademy?sub_confirmation=1 Don't forget to follow us on social to stay up-to-date on the latest Altium Academy content. 👉 Follow Altium on TikTok: https://www.tiktok.com/@altiumdesigner 👉 Follow Altium on Twitter: https://twitter.com/altium 👉 Follow Altium on Linkedin: https://www.linkedin.com/company/altium/ 👉 Follow Altium on Facebook: https://www.facebook.com/AltiumOfficial/ The Altium Academy is an online experience created to bring modern education to PCB Designers and Engineers all across the world.
