Hybrid integrated circuit
From Wikipedia, the free encyclopedia
An (orange-epoxy) encapsulated hybrid circuit on a printed circuit board.
A hybrid integrated circuit, HIC, hybrid microcircuit, or simply hybrid is a miniaturized electronic circuit constructed of individual devices, such as semiconductor devices (e.g. transistors and diodes) and passive components (e.g. resistors, inductors, transformers, and capacitors), bonded to a substrate or printed circuit board (PCB). If the components are on Printed Wiring Board (PWB) then, according to the definition of MIL-PRF-38534, it is not considered hybrid. A PCB can be called PWB if does not contain embedded components. Hybrid circuits are often encapsulated in epoxy, as shown in the photo. A hybrid circuit serves as a component on a PCB in the same way as a monolithic integrated circuit; the difference between the two types of devices is in how they are constructed and manufactured. The advantage of hybrid circuits is that components which cannot be included in a monolithic IC can be used, e.g., capacitors of large value, wound components, crystals, inductors.
