　　In the past few years, surface mount fuses have been the most valuable variety among small fuses, but the price competition they face is also fierce. The average unit price of the product has decreased by 20-30%. In recent years, while surface mount fuses have gained widespread popularity, they have also made continuous breakthroughs and innovations in technology.

　　From the perspective of global fuse production distribution, a large proportion of electronic assembly factories are located in China, with over 40% of actual applications in China. The main market of surface mount fuses is in Asia, and is concentrated in Chinese Mainland, Taiwan, Japan and South Korea. Many Japanese and South Korean companies also have factories in China, making China an important market for surface mount fuses.

　　The actual annual consumption of surface mount fuses in the former Greater China region (including Japanese, Korean, Hong Kong and Taiwan funded factories in Chinese Mainland) accounts for about 50% of the global consumption of patch fuses and nearly 15% of the total consumption of small fuses. The above is a brief explanation by the editor about the market prospects of SMD chip fuses,

　　Choose an appropriate inspection method. For components that can be inspected, inspectors should select some components for random inspection while minimizing damage to the original packaging; For devices that cannot be inspected, do not unpack them, only inspect their appearance and integrity to avoid moisture absorption and oxidation during the inspection stage. 3.3 The inventory and electrical installation site environment should be maintained at appropriate temperature and humidity in accordance with relevant standards. Humidity sensitive SMDs are packaged in moisture-proof packaging bags with desiccants when leaving the factory. The standard ones should also be printed (pasted) with the user manual 0 and indicate the moisture-proof validity period (usually one year). On the premise of meeting this packaging requirement, the standard temperature of the device library is generally 20 ℃ -30 ℃, and the comfort value is 20 ℃ -25 ℃; The standard humidity is 30%~70%, and the comfort value is 40%~70%. The environment of the electrical installation site should be controlled within the following range: * The ambient temperature is (23 ± 3) ℃, the general temperature is 17 ℃~28 ℃, the extreme temperature is 15 ℃~35 ℃, and the printing workshop * The ambient temperature is (23 ± 3) ℃; The relative humidity is between 45% RH and 70% RH. In addition, using anti-static bag vacuum packaging for devices that are not currently in use is also a good measure to prevent moisture absorption and oxidation.
