Welcome back to Adhesion Matters. Adhesives have quietly evolved from simple bonders into indispensable, high-performance materials in PCB manufacturing—critical for thermal management, electrical performance, and environmental resilience. In this episode, we explore how adhesives empower modern electronics: enabling miniaturization, supporting flexible and high-density circuits (think HDI and flex PCBs), and meeting rising demands in consumer tech and electric vehicles.
You’ll discover how specialized adhesive families—epoxies, acrylics, silicones, polyamides, polyurethanes—each offer unique strengths, from rigidity and heat-resistance to flexibility, reworkability, and flame protection. Hear how engineers tailor selections based on criteria like thermal conductivity, environmental durability, and the ability to withstand mechanical or thermal stress over time.
Learn about real-world applications across the PCB manufacturing spectrum: surface mount adhesive placement, underfills, die attaches, conformal coatings, potting compounds, encapsulants, and even thermal interface materials that control heat in EV power systems.
Finally, we look ahead at the future of adhesive innovation: extreme miniaturization, advanced thermal management for EVs, and a push for eco-friendlier, halogen-free, low-toxicity formulations.
