With the rapid development of modern electronic information technology, integrated circuit chip packaging forms are also emerging in an endless stream, and the package density is getting higher and higher, which greatly promotes the development of electronic products to multi-function, high performance, high reliability and low cost.So far, through hole technology (THT) and surface mount technolog...
Recently, Professor Ni Zhenhua from the School of Electronic Science and Engineering at Southeast University, Professor Lv Junpeng from the School of Physics, Professor Liu Hongwei from the School of Physical Science and Technology at Nanjing Normal University, and Professor Zhou Peng from the School of Microelectronics at Fudan University collaborated to propose a van der Waals light-emitting dio...
Tool has started pre-sales for the F1 Ultra, a 20 watt fiber and diode dual laser engraving machine. OEMs have stated that it is a win-win product and its so-called "flagship" model.Fiber lasers are mainly used for metal materials and usually work faster than diode lasers, but other materials have better performance when using diode lasers. F1 Ultra aims to bridge this gap by using a power of 20W ...
3D printer manufacturer Raise3D has launched a new Fused Manufacturing (FFF) 3D printer series called Pro3 HS and a supercore filament series.The Pro3 HS series is equipped with a motion control system, which improves speed, accuracy, and simplifies the manufacturing of large composite components. Raise3D's Hyper Core filament has a dense fiber core and well arranged carbon fibers, which can enha...
1. Research backgroundDirected energy deposition (DED), as an efficient and economical technology in the field of additive manufacturing (AM), is widely used in the manufacturing of metal materials. However, its high heating and cooling rates, as well as significant temperature gradients, often lead to rapid solidification, forming cross layer columnar grains and internal defects, seriously affect...
