激光微细熔覆快速原型制造厚膜电感元件

Study on Thick Film Inductors Fabricated by Laser Micro-cladding and Rapid Prototype

采用激光微细熔覆快速制造技术直接将电感元件集成在电路板上,使之由插装或表面贴装元件直接转化成平面膜式电感,大大减少了焊点,缩短互连,减少了占用面积,从而提高了可靠性和电性能。另外,不需要掩模的制作和高温烧结,简化了工艺,降低了成本,提高了效率。

The inductors were directly integrated in circuit by the technique of laser micro-cladding and rapid prototype, which makes plug-in or chip inductors to be transformed into thick-film plat inductors, and point of weld is less and stacked length is shorten, used area decreases, thereby, electric performance and reliability are improved. Moreover, processing is simple without the need of mask and high temperature sintering and cost is low with the exception of high efficiency.
