The Price of Capacitor Resistance Rises Wildly, and LED Display Screen Makes Innovation for Capacitor Resistance
Since the wave of environmental protection, the shortage of raw materials and the rise in prices have continued in the past two years. From the perspective of the LED display industry, from PCB to packaging materials, and even to capacitor resistance. Some news shows that since last year, the price of capacitor resistance has gone up by dozens of times. Not only that, the shortage is also very serious.So what is capacitance resistance and what is its function? In short, the capacitance resistance has the function of protecting the circuit and changing the current. For LED display products, capacitance resistance is also a very important component. There is capacitance resistance on each unit board.In 2018, the price rise trend of capacitor resistance was more frequent, with an increase of 20% - 30%. Here is a price rise notice issued by Fenghua high tech and Lizhi electronics, the domestic leaders of passive components in April. Among them, Lizhi electronics not only increased the resistance of the whole series of thick film chips by 20% - 30%, but the price of the whole series of chip thermistors of Fenghua high tech increased by 30% - 80%!
Capacitor resistance continues to soar and out of stockAt present, the biggest problem of capacitor and resistor products is not continuous surge, but out of stock!
According to the small editor of LED display channel told by Huaqiangbei's component trader dealing in resistors, the supply of resistors in the market has changed greatly compared with the previous two months. The scope of product supply gap has spread from general resistors to high-precision resistors, and the delivery cycle has become longer. In terms of market demand, large terminal demand is still very tight. Although it is now in the middle and off-season of the year, the market demand has cooled down. Before the peak season in the second half of the year, the first-line and second-line manufacturers are stepping up the preparation of goods.
There are many reasons for the shortage of capacitor resistance passive components. First, the price rise of upstream raw materials of passive components; Second, Japanese manufacturers gradually withdraw from the "old product group" of medium and large sizes of 0805 and 0603; Third, the downstream demand for capacitors and resistors has increased, especially in the hot and high priced markets such as new energy vehicles and smart speakers, which has pushed the prices of capacitors and resistors up more than 10 times; Finally, the channel stores goods and deliberately raises the price.It is difficult to solve the problem of capacitor resistance price rise and shortage in a short time. According to insiders, "this wave of price rise may continue throughout 2018, and manufacturers' production expansion plans are limited." moreover, there is a "warning" that enterprises wantonly expanded production in early years, which eventually led to serious overcapacity. This wave of shortage tide, manufacturers are relatively conservative in their production expansion plans, and the scale of production expansion is only about 10-15%. This means that the capacity supply of capacitors and resistors is still difficult to ease in the short term.Innovative solutions to alleviate cost problems
It may be because the cost of capacitor resistance products is low, even after such a sharp rise, the price will not be too sensitive. The industry pays much more attention to the price rise of PCB than that of capacitor resistance. However, with the rising price rise of capacitor resistance, it will bring greater pressure on the cost of LED display manufacturers, especially the problem of shortage of goods, How should LED display manufacturers deal with it?
Mr. Wang Jun, general manager of the guide optoelectronics, disclosed to us that the industry has made an innovation in terms of capacitor resistance, that is, integrating the function of capacitor resistance into the driving IC. In this way, each unit board can save a certain cost and ensure the stability of the product. It has the following four advantages: 1. Save the cost of capacitance and resistance; 2. Greatly save the patch cost and improve the patch efficiency; 3. IC integration is improved (PCB wiring is simpler and can be repaired without professional maintenance technicians); 4. Reduce power consumption, save energy and protect the environment. According to Xiaobian, at present, the powerful giant color in the industry has launched relevant led monochrome products and began to vigorously promote them.
Innovation is the eternal power of product development. I believe that in the future, with the continuous optimization of the "go" capacitor resistance scheme, this scheme can also be promoted in the full-color display screen, and even better and better solutions than this "go" capacitor resistance will not only save more costs for manufacturers, but also bring better products to customers.
