本發明係提供一種電感元件之成型方法，尤指具有扁平外形、體積小之電感元件的成型方法，透過層疊狀線圈層間以扁平狀線圈電性連結、導通，產生電磁感應作用，成型為電感元件可供電路板使用。The invention provides a method for molding an inductance component, in particular, a molding method for an inductance component having a flat shape and a small volume, which is electrically connected and electrically connected through a laminated coil layer through a laminated coil layer to generate an electromagnetic induction function, and is formed into an inductance component. Available for board use.
按，在眾多的電子元件中，電感元件係屬於輔助性質，而主要作用在於阻礙電流的變化，藉以維持電子產品的穩定性，則電感元件結構形式可依應用線路搭配不同，設計出不同構造，且在目前常用之電感元件，其應用之模式大概分為二大類，一為訊號用途，例如：能量儲存及抑制瞬間電流等，另一類即為雜訊抑制用途，例如：防電磁干擾之抑制(Electromagnetic Disturbance，EMI)及雜訊濾波等功能。According to the numerous electronic components, the inductance component belongs to the auxiliary property, and the main function is to hinder the change of the current, so as to maintain the stability of the electronic product, the structural form of the inductance component can be designed according to different application lines, and different structures are designed. In the current commonly used inductive components, the application modes are roughly divided into two categories, one for signal applications, such as energy storage and suppression of instantaneous current, and the other is for noise suppression purposes, such as: suppression against electromagnetic interference ( Electromagnetic Disturbance, EMI) and noise filtering.
而電感元件的特性係受到鐵芯材料所影響，鐵芯位於電感內部線圈中心位置處，並分為陶瓷及鐵氧體材料，且陶瓷鐵芯為應用於訊號用途，如：陶瓷繞線電感及積層陶瓷電感；至於鐵氧鐵芯則用於抑制電瓷干擾，如：扼流器(Power Choke)、陶鐵磁珠(Ferrite Bead，FB)及磁鐵芯(Ferrite Core)。The characteristics of the inductive component are affected by the core material. The iron core is located at the center of the inner coil of the inductor and is divided into ceramic and ferrite materials.
