What is industrial control/automation PCB?

Industrial control refers to industrial automatic control, mainly through the combination of electrical, electronic, mechanical, and software to achieve. It is industrial control or factory automation control，mainly refers to the use of computer technology, microelectronic technology, and electrical ways to make the factory production and manufacturing process more automated, efficient, accurate, and with controllability and visibility. With the development of science and technology, the level of industrial automation is getting higher and various industrial automation equipment keeps emerging, such as elevators, industrial power supplies, servo motors, assembly robots, industrial control intelligent manufacturing, etc., which are all running for a long time. In the industrial control PCB Assembly , the routing setting is a crucial link that directly affects the stability and reliability of the circuit board. Therefore, in industrial control electronics, the requirements are very similar to industrial control level requirements, including usage in harsh environments, long life, high reliability, durability, etc. Compared with industrial control level products, industrial grade products may be more simplified in design and manufacturing, but still need to ensure their reliability and performance stability. Industrial grade products can be customized and adapted according to meet the specific requirements of different industries within the industrial environment. Industrial control PCB has special circuit boards and general circuit boards. Special circuit boards are designed specifically for particular functions, such as temperature control circuit boards. After purchase, the input port is connected to a thermocouple, and the output port is connected to a heat contactor or solid- state relay to control heating equipment for temperature control and flow. There are also control panels, motion control panels, and so on. General circuit boards, after the user's own secondary development, the majority of them can be programmed to achieve specific functions with wide applications. For example, PLC(Programmable Logic Controller) is a universal industrial control board. After the user writes the program and compiles the input, it can complete various functions like digital input, analog input ports, high-speed counter ports, digital output ports, analog output ports, and some even have communication capabilities. The operational environment of industrial equipment is complex. The function of the Industrial control PCB is based on industrial automation control, and the PCB should work commonly under high temperature, high humidity, and high corrosion conditions. There should be no malfunctions during long-term use. PAD manufacturers establish unique processes and testing methods based on the specific characteristics of industrial control PCBs, ensuring that these PCBs meet the quality requirements of industrial equipment.

Certifications for industrial control/automation PCBs

·ISO standard: ISO (International Organization for Standardization) is the abbreviation of the International Organization for Standardization. Strict standardization is carried out for aspects such as product quality management, such as ISO 9001, ISO 14001, etc. ·IPC standard: IPC is the abbreviation for the integrated production and manufacturing process of the electronics industry. In response to various testing needs in industrial automation applications, IPC standards are used to regulate and test the quality of different brands and products, such as IPC-2221, IPC-A-610, etc. ·IPC-6012: Specifies the qualification and performance requirements for rigid printed circuit boards, including base material, conductor configuration, hole requirements, surface and internal conductors, and marking. ·IPC-2221: Defines the design requirements for printed circuit boards, including board layout, trace width and spacing, via dimensions, and other design aspects. ·UL 94: Tests the flammability of plastic materials used in the construction of electronic equipment. PCBs that meet this standard are made of flame-retardant materials. ·RoHS: Is a directive that restricts the use of six hazardous substances in the manufacture of electronic and electrical equipment, and industrial PCBs must comply with this directive. ·CE Standard: The CE mark means compliance with all relevant regulations and requirements of the European Union, such as electromagnetic compatibility, safety, etc., and indicates that the product complies with the corresponding regulations and directives. ·FCC Standard: FCC is the abbreviation of the Federal Communications Commission of the United States, which is responsible for supervising and managing the policies and regulations of the United States in the fields of broadcasting, television, communications, electronics and related equipment.
