Two, the characteristics of production and management in power industry switch
    1¡¢The production characteristics
    With the structure of electronic products and electronic design are the same, so the power supply requirements are the same, in the design and manufacture, to customer specifications, as the standard design and production.
    Switching power supply products are divided into standard and non - standard products, generally speaking, standardized product orders larger volume, lower margin, competition is intense, and non standardized product order batch is lesser, but gross margin is higher, less competition. Standardized products are mainly used in consumer electronic products, PC power and other fields, and non customized product application and communication power supply, standard of new energy and industrial power and other fields. Standard switching power supply enterprise according to customer orders to organize production, enterprises generally not have inventory. Make to order refers to the receipt of customer orders, modify the design, manufacturing and assembly based on existing product scheme, or re design of research and development, provide the final production of customized products to customers. Enterprises in the receipt of customer orders, according to the specific requirements of the order, designed to meet the special requirements of customers customized products, from the selection of suppliers, raw material requirements, design process, manufacturing process and the delivery of the finished product and so on are decided by customer orders.

    Unlike the mass customization, customization of switching power supply is more small batch customization, in order to better control costs, thereby rapidly to provide customers with customized products with low cost, high quality, put forward a higher request to enterprise R & D, production management and procurement capacity, so enterprises must have the agile product development and design ability and material purchasing ability, specifically for a product design of the traditional rigid production line will also be able to meet the replacement of flexible production line manufacturing diversified and personalized requirements.
    2¡¢Profit characteristics
    Switch power production enterprises according to the product positioning and different grades, its profit pattern is different. Technical content is low in the low-end products, mostly to take the processing fee is the main source of profits. Many consumer electronic products supporting the production of switching power supply enterprise general standard of low power, low price competition, to give priority to, to scale operation to win, profitability is poor; in the high-end products as high-end electronic products, industrial control equipment supporting, the switching power supply efficiency, accuracy and reliability requirements of the higher requirements, manufacturing enterprises have strong research and development capabilities and superb manufacturing level, high added value products, so the high-end switching power supply enterprise bargaining ability, profit ability is strong. The strength of the large power supply enterprises basically are beginning to transition from OEM to ODM, providing the research design to processing one-stop service for customers, the enterprise brand has a good reputation in the industry, all obtains the customer approval in product quality and R & D capability, has ability of exterior design inside design and the products.
    3¡¢The characteristics of the market
    Because the switching power supply industry to customize based, enterprise sales closely integrated with the orders, sales behavior occurred in the manufacturing of products before. At the same time, enterprises also develop standards to promote the products, markets and customers, and actively expand the electronic industry customers, show the company R & D design ability, the scale of production and quality management ability has become an important means of marketing. At present, the switching power supply industry to expand sales channels of the main ways to participate in trade fairs, recommend each other in professional print media and industry website promotion and customer, and have the high quality customer resource is the most direct embodiment of strength of enterprises.
