Episode 5: Multi-Layer Thick Film – Stacking Functionality

Multi-layer thick film technology layers conductors, resistors, and dielectrics on ceramic substrates like alumina, creating compact, high-function circuits. Screen-printed and fired at 850°C, it uses vias for 3D connectivity, ideal for wearables and IoT. Precision is vital—misalignment causes shorts, and thermal stress can create cracks.
