PCB Technical - Development and improvement of control panel design

Commonly used home appliance control board design and development is also a kind of circuit board. Although its application range is not as broad as that of circuit boards, it is smarter and more automated than ordinary circuit boards. Simply put, a circuit board that can play a control role can be called a PCB control board. The control panel is one of the core components of various household appliances, and most of the specific program functions are realized by this component. In a sense, the quality and life of the household appliances are determined by the quality of the control panel. Controlling the quality of control panels is the foundation of the survival and development of major control panel companies. Choosing a high-quality control board is the key for home appliance companies to improve the quality of PCB products and enhance the competitiveness of the PCB market.

Now that the Internet of Things is becoming more and more popular, the home appliance control panel is also integrated with the Internet of Things technology. The home control panel here not only refers to household use, but also many commercial control panels. There are roughly these categories: home appliance IoT controllers, smart home control systems, RFID wireless curtain control panels, cabinet heating and cooling air conditioning PCB control panels, electric water heater control panels, household range hood control panels, washing machine control panels, humidifier control panels, Dishwasher control panel, commercial soybean milk machine control panel, ceramic stove control panel, automatic door control panel, etc., electric lock control panel, intelligent access control system, etc.

It is understood that the current subdivision of the PCB control panel industry is not clear, and can be roughly divided into major appliance control panels, such as washing machine control panels, air conditioning control panels, range hood control panels, etc.; small household appliances control panels, such as soymilk control panels, Induction cooker control panel, dishwasher control panel, pressure cooker control panel, etc. Most of the manufacturers that produce control panels for small household appliances belong to extensive processing and can produce various control panels for small household appliances. Such a production mode is not conducive to differentiated competition among enterprises. However, with the continuous advancement of technology and the deepening of economic globalization, some powerful control panel manufacturers have also introduced some advanced technologies and production concepts. For example, the induction cooker control board produced by Jinxin Electronics adopts German automatic phase lock technology and automatic working frequency tracking. It has IGBT soft start function, overheat protection, overcurrent protection, through protection, surge current protection, surge voltage protection, and undervoltage. Over-voltage protection, short-circuit protection between turns of the induction coil, and response time less than or equal to 0.2US, which greatly improves the quality and service life of the control board.

Generally, the smart controller industry is typically PCB technology-intensive, and PCB technology innovation and PCB design capabilities are the key to competition among enterprises. However, the author found after visiting and understanding that if only relying on technology and design capabilities, for some small and medium-sized intelligent controller companies, it will not become their "iron rice bowl" for survival. On the contrary, lower prices, lower costs, and volume will become many small and medium-sized enterprises. The survival choice that home appliance control panel manufacturers have to face.

The development of smart home appliances in the past two years can be regarded as rapid progress. From the well-known various "cloud" appliances to "net" technology, from the popularization of new concepts to the interconnection of PCB technology, the innovation of the smart home appliance industry can always start from the concept. Create PCB market demand. As home appliance accessories, especially in the dual considerations of PCB technology and cost, small and medium home appliance intelligent control board companies obviously have to face more growth games. However, how to break through many competitors and how to pave the way for the brand will inevitably become a problem that many operators have to think about.
