In this quick design tip, we answer a viewer question about opening the solder mask over microstrip antenna feed lines and explain the signal integrity reasoning behind it. The key is loss tangent: solder mask has a loss tangent around 0.025, roughly ten times higher than the 0.002 typical of low-loss RF substrate materials. When you route a microstrip line on a high-performance RF laminate and then coat it with solder mask, you're effectively layering a lossy dielectric on top of a low-loss one, undoing the advantage of the RF material. Using real insertion loss data, we walk through what happens to a bare copper interconnect versus a mask-covered trace as frequency climbs. At around 1 GHz the difference is negligible, but once you reach Wi-Fi frequencies the added loss becomes noticeable, and above 10 GHz it becomes significant. That's why high-frequency RF microstrip routing in the gigahertz range is typically left mask-open. If you design RF boards, antennas, or high-speed interconnects, this tip will help you avoid unnecessary insertion loss and keep your high-frequency signals clean. 💡 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.
