1, integrated circuit.
Two, two, triode.
3. Special electronic components.
The product classification of integrated circuit chips can be divided into the following categories:
First of all, the types of integrated circuits are usually classified according to the number of electronic components (such as transistors).
SSI (Small Integrated Circuit), the number of transistors is 10 ~ 100.
MSI (Medium Integrated Circuit) has 100 ~ 1000 transistors.
LSI (large scale integrated circuit), the number of transistors is 1000 ~ 100000.
Very large scale integrated circuit with more than 100000 transistors.
Second, classified by functional structure.
Integrated circuits can be divided into analog integrated circuits and digital integrated circuits according to different functions and structures.
Third, according to the production process classification.
Integrated circuits can be divided into semiconductor integrated circuits and thin-film integrated circuits according to their manufacturing processes. Thin film integrated circuits are divided into thick film integrated circuits and thin film integrated circuits.
Four, according to the different types of conductivity classification.
Integrated circuits can be divided into bipolar integrated circuits and unipolar integrated circuits according to conductivity types. Bipolar integrated circuits have complex manufacturing process and high power consumption, that is to say, there are TTL, ECL, HTL, LST-TL, STTL and other types of integrated circuits.
Monopolar integrated circuits are simple in manufacturing process, low in power consumption and easy to be made into large-scale integrated circuits. The representative integrated circuits are CMOS, NMOS and PMOS.
5. Classification by purpose.
Integrated circuits can be divided into integrated circuits for TV sets according to their uses. Integrated circuits of audio, DVD player, video recorder, computer (microcomputer), electronic organ, communication, camera, remote control, language, alarm and various special integrated circuits.

Common sense of integrated circuit testing
Understand the working principle of integrated circuits and related circuits before inspection. Before checking and repairing the integrated circuit, we should be familiar with its function, internal circuit, main electrical parameters, the function of each pin, the normal voltage and waveform of the pin and the working principle of the circuit composed of peripheral components. If the above conditions are met, the analysis and inspection will be much easier.
Do not cause short circuit between pins during testing. When measuring voltage or waveform with oscilloscope probe, the contact pin or probe should not be short-circuited between pins of integrated circuit due to sliding. It is best to measure on the peripheral printed circuit directly connected to the pin. Any instantaneous short circuit is easy to damage the integrated circuit, so be more careful when testing flat packaged CMOS integrated circuits.
It is forbidden to touch TV, audio, video and other equipment with live floor with grounding test equipment without isolation transformer. It is strictly forbidden to directly test TV, audio, video and other equipment without power isolation transformer with instruments and equipment with grounding shell.
