PCBA Products - Controller​ PCB

A controller pcb is an auxiliary device consisting of a series of electronic components and circuits that can precisely control and regulate electronic equipment. At the same time, the pcb controller is also the manager of the circuit system in the electronic equipment, it can optimise and improve the circuit, improve the function and performance of the equipment.

How controller pcb works

A controller pcb is an electronic device that integrates circuit components and signal processors to control and manage the operation of other electronic devices. It controls the operation of the device by receiving input signals, which are processed and scanned by internal circuits and output corresponding electrical signals. The working process of the pcb controller can be simply divided into three steps: input, processing and output.

1.Input stage: the controller pcb receives input signals from the external environment through various sensors. These sensors can be photosensitive resistors, temperature and humidity sensors, acceleration sensors, etc., whose role is to convert information from the external environment into electrical signals.

2.Processing stage: After receiving the input signals, the processor inside the controller pcb carries out digital processing to convert the signals into data that can be understood by the computer. Usually, the pcb controller will be equipped with a microcontroller or embedded processor to complete the processing and analysis of the signal.

3.Output stage: After internal processing, the pcb controller will output control signals to drive other devices according to the preset logic and algorithms. These control signals can be current, voltage, etc., as needed to control the device's switch, speed, temperature and other parameters.

Controller pcb enables precise control of other electronic devices by working in the input, processing and output stages. Different types of pcb controller has different working principles and circuit designs to suit different types of devices and applications.

Common components on controller pcb

Resistors

Resistors are one of the most basic components on a pcb controller and their main function is to limit current or adjust voltage. By converting electrical energy into thermal energy consumption, resistors are able to regulate circuits using different resistance values.

Capacitors

Capacitors are another common component on pcb controller and are usually used to store electrical energy or to switch on and off circuits. As a storage unit for energy, capacitors are able to store charge and act as a filter in high frequency circuits, smoothing the circuit signal.

Transistor Devices

Transistor devices are important power amplifiers on controller pcb that control the amount of output power by regulating the current. It plays an indispensable role in modern electronic technology and is widely used in a variety of electronic devices such as televisions, audio equipment, and electronic clocks.

Integrated Circuit

The integrated circuit, or chip, is one of the most critical components on a pcb controller.It integrates thousands of electrical components on a tiny chip with excellent performance and high reliability. Integrated circuits,including digital integrated circuits, analogue integrated circuits, and microprocessors,are used in a wide variety of control and computing tasks in a wide range of fields, and are an indispensable part of modern electronic products.

In the industrial field, these controller pcbs are often referred to as power control boards, which are further subdivided into two types:medium-frequency and high-frequency. Medium-frequency power control boards mainly work with medium-frequency power equipment such as medium-frequency electric furnaces, quenching machine tools, forging equipment and so on.High-frequency power supply control panels are divided into two types: IGBT and KGPS, of which IGBT is widely used in high-frequency equipment due to its energy-saving characteristics. Examples of common control boards in the industrial field include control boards for CNC stone engraving machines, plastic shaping machines, liquid filling machines, self-adhesive die-cutting machines, automatic drilling machines, automatic tapping machines, positioning and labelling machines,ultrasonic cleaners and other equipment.

As for motor controller pcb, motors, as the core execution parts of automation equipment, have a wide range of drive controller pcb, such as AC induction motors, brushed DC motors, brushless DC motors, permanent magnetic synchronous motors, stepper motors, asynchronous motors, synchronous motors, servo motors, tubular motors and other drive pcb controller.

With the development of the Internet of Things technology, home appliance controller pcb is also integrated into this technology, not only limited to home use, but also commercial control boards, such as home appliance Internet of Things controllers, smart home systems, wireless curtain control boards, heating and cooling air-conditioning controller pcb, electric water heaters, hoods, washing machines, humidifiers, dishwashers, commercial soya bean milk machine, ceramic stoves, automatic doors, electric locks and intelligent access control control boards.

Medical device pcb controller is mainly used for medical instruments, responsible for instrument operation control and data acquisition, such as medical data acquisition, electronic blood pressure monitor, body fat meter, heart rate meter, massage chair, home physiotherapy and other controller pcb.

Automotive electronic pcb controller is applied to automobiles to monitor the vehicle status in real time and provide a convenient and safe driving experience, such as car refrigerator, LED taillight, audio, GPS positioning, tyre pressure monitoring, reversing radar, electronic immobilizer, ABS controller and other controller pcb.
