Identifying Integrated Circuit Symbols and Layout
Integrated circuits, also called "chips", are electronic circuits where all the components (transistors, diodes, resistors and capacitors) has been manufactured in the surface of a thin substrate of semiconductor material.
Integrated circuit is designed to save extra space on modern electronics.
In electronics, an integrated circuit (also known as IC, microcircuit, microchip, silicon chip, or chip) is a miniaturized electronic circuit (consisting mainly of semiconductor devices, as well as passive components) that has been manufactured in the surface of a thin substrate of semiconductor material. Integrated circuits are used in almost all electronic equipment in use today and have revolutionized the world of electronics.
In mobile phones it is packed with each desired certain applications purpose like
Power Management, Baseband Processor, Application Processor , Memory Storage, Audio Codecs, Bluetooth and Wi-Fi Ciruits.
Some large pack chips composed of many circuits and certain application both in-place in one packaging.
IC Chips are very delicate to handle with and troubleshoot if found faulty, it needs a little bit deep knowledge and understanding on how that chips works on a particular circuit. Experience is the best tool to handle with it.
