SMD NTC thermistor produced by EXSENSE Electronics Technology Co., Ltd., with high precision, small size, high-reliability ceramic structure, rapid response and other characteristics, is widely used in lithium battery, mobile power equipment, IT equipment, hybrid design multi-functional module.
With the development of miniaturized equipment, lithium battery has become an indispensable core to ensure the operation of equipment. Due to lithium batteries are mostly used in consumer electronics, household appliances, power tools, etc., the size of the protection board also needs to be smaller. Therefore, in order to ensure the normal operation of the lithium battery protection board, NTC thermistor that plays the role of temperature monitoring and temperature controlling will also adopt the smaller size of the SMD NTC thermistor. The mounted technology of the thermistor is called Surface Mounted Technology (SMT), which is the most popular Technology and process in the electronic assembly industry. The basic process elements of SMT are solder paste printing → parts mounting → reflow soldering →automated optical inspection (AOI) → maintenance → board cutting.
SMT has the advantages of high assembly density, small size and light weight of electronic products. The volume and weight of SMD NTC thermistor is only about 1/10 of that of traditional plug-in type NTC thermistor. After using SMT, the volume of electronic products is reduced by 40%~60%, the weight is reduced by 60%~80%, the reliability is high, the anti-vibration ability is strong, the defect rate of solder spot is low, the high frequency characteristic is good, and the electromagnetic and radio frequency interference is reduced. It can effectively improve production efficiency, achieve automation, reduce the cost by up to 30%~50%, save materials, energy, equipment, manpower, time and so on.
In lithium battery protection board, the use of SMD NTC thermistor instead of plug-in type NTC thermistor has the following advantages:
First, save production and processing hours;
Second, to avoid the situation of contact shift of plug-in type NTC thermistor;
Third, reduce the appearance of short circuit;
Fourth, avoid displacement and fracture, reduce the probability of man-made damage.
