High Quality Multilayer PCB Assembly

What is a main PCB assembly?

PCBA Manufacturing whose molecular structure is changed during production and processing in a factory is called a components
The Electronic Components are divided into:
1. Active device, its main features are: (1) It consumes electric energy by itself (2). It also needs an external power supply.
2. Discrete devices are divided into (1) bipolar transistors (2) field effect transistors (3) thyristors (4) semiconductor Electronic resistors and capacitors.
3. The analog integrated PCB circuit mainly refers to an integrated circuit that is integrated with analog circuits composed of capacitors, resistors, transistors, etc. to process analog signals. There are many analog integrated circuits, such as integrated operational amplifiers, comparators, logarithmic and exponential amplifiers, analog multipliers (dividers), phase-locked loops, power management chips, etc. The main components of analog integrated circuits are: amplifiers, filters, feedback circuits, reference source circuits, switched capacitor circuits, etc. Analog integrated circuit design is mainly obtained through manual circuit debugging and simulation by experienced designers. Most of the corresponding digital integrated circuit design is automatically synthesized by using hardware description language under the control of EDA software.
4. Digital integrated circuit is a digital logic circuit or system made by integrating components and wiring on the same semiconductor chip. According to the number of gate circuits or components and devices contained in digital integrated circuits, digital integrated circuits can be divided into small-scale integrated (SSI) circuits, medium-scale integrated MSI circuits, large-scale integrated (LSI) circuits, very large-scale integrated VLSI circuits, and Ultra Large Scale Integration (ULSI) circuit. Small-scale integrated circuits contain less than 10 gates, or the number of components does not exceed 100; medium-scale integrated circuits contain between 10-100 gates, or the number of components is between 100-1000; The large-scale integrated circuit contains more than 100 gate circuits, or the number of components is between 10-10; the very large-scale integrated circuit contains more than 10,000 gate circuits, or the number of components is between 10-10; The number of components of a very large scale integrated circuit is between 10 and 10. It includes: basic logic gates, flip-flops, registers, decoders, drivers, counters, shaping circuits, programmable logic devices, microprocessors, microcontrollers, DSPs, etc.
