Microvia reliability is pivotal in electronic devices, ensuring stable connections within PCBs. These minute conduits, typically under 150 micrometers, demand precision in design and manufacturing. Robust materials and advanced techniques, like laser drilling, fortify microvias against mechanical stress. Rigorous testing, including thermal cycling, guarantees their resilience under varied conditions. Ultimately, microvia reliability safeguards the overall performance and longevity of modern electronic systems.
