Hybrid circuits are one of two groups of integrated circuits. Hybrid systems are plates made of an insulator on which conductor layers are applied. Then layers of insulator and resistive material are applied. Miniature electronic components are introduced successively. A system constructed in this way is usually closed in an insulated housing. Hybrid systems make it possible to obtain the exact value of individual components. The discussed systems can be divided into thin and thick layers due to the thickness of the layers.
