1, high reliability, strong vibration resistance. Low defect rate of solder joint. Good high frequency characteristics. Reduced electromagnetic and radio frequency interference. Easy to automate and improve production efficiency. Reduce the cost by 30%~50%. Save materials, energy, equipment, manpower, time, etc.
2, a typical feature of TSOP is around the package chipMake pins, such as SDRAM IC has pins on both sides, SGRAM IC has pins on all sides. TSOP is suitable for SMT surface mounting technology to install wiring on the PCB, package dimensions, reduce parasitic parameters, suitable for high-frequency applications, easy to operate, high reliability.
3, because there is no dispensing machine in C, D, E, F, G line, so after printing the solder paste, the substrate needs to be lifted to A or B line for dispensing operation, and the quality of the glue needs to be fully checked, because the glue tinning process is divided into R and C components, so the defects are less, the eye inspection personnel will draw a to assist in printing and checking the red glueThe production line runs smoothly. Ten PCB baking time (4 hours), return temperature time (2 hours).
4, with the use of electronic moisture-proof box more and more widely, in many industrial places are required to use electronic moisture-proof box discontinuous materials, semi-waste, waste moisture and oxidation storage, especially in SMT and LED occupation, the use of electronic moisture-proof box is widespread. The materials stored in the electronic moisture-proof box are also gradually classified as moisture-sensitive components. The IPC specification for the occupational use of electronic moisture-proof boxes is first of all to distinguish the intermittent humidity sensitivity level of MSD moisture-sensitive components.
5, easyAchieve automation and improve production efficiency. Reduce the cost by 30%~50%. Save materials, energy, equipment, manpower, time, etc. [Edit this paragraph] Why should we pursue miniaturization with SMT electronic products, the previously used punch plug-in components can not be reduced. The function of electronic products is more complete, and the integrated circuit (IC) used has no perforated components, especially large-scale, highly integrated ics, and surface patch components have to be used.
6, because there is no dispensing machine in C, D, E, F and G lines, it is necessary to lift the substrate to A or B line for dispensing after printing the solder paste, and it needs to be fully checkedAs an indirect supplier of Apple products, our subsidiary Mingheng Metal provides alloy raw materials for many Apple products. Wansheng Shares.

2, it is also due to these performance advantages, gallium nitride has a wide range of applications in the consumer fast charging source market. Charging head network statistics show that at present, dozens of mainstream power manufacturers have opened up GAN fast charge product lines, and launched hundreds of new GAN fast charge products. Huawei, Xiaomi, OPPO, Meizu, Samsung, ZTE, Nubia, Meizu, realme, Dell, Lenovo and other well-known mobile phone/laptop brands have also entered the game.
3, Xiamen SAN An Integrated Circuit Co., Ltd. was established in 2014, is a LED chip manufacturing company SAN an Optoelectronics subsidiaryThe company, which operates on gallium nitride and gallium arsenide technologies, is a foundry specializing in compound semiconductor manufacturing for the RF, millimeter wave, power electronics, and optical markets, with industry integration capabilities in substrate materials, epitaxy growth, and chip manufacturing. 4, in other words, Samsung S21 cancel the standard charger this move will have a profound impact on the entire third-party fast charging accessories market. 19 factories launched 28 Samsung S21 fast charging head network through research, there are a number of fast charging electrical factories began to layout 25W, and compatible with 25W PPS fast chargingCharger product line to meet the market growth brought about by the non-standard charger for Samsung S21 mobile phones.
