可提升产量一次成型的电感制造方法

Once-forming method for manufacturing inductance capable of improving yield

Abstract

本发明是一种可提升产量一次成型的电感制造方法,其包含下列步骤:第一步骤:备料,准备线圈与铁粉;第二步骤:线圈定位,将第一步骤的线圈定位于下模具的容置槽内;第三步骤:填入铁粉,将第二步骤中已定位线圈的容置槽内填入铁粉;第四步骤:挤压,是将第三步骤已填入铁粉的容置槽以上模具挤压容置槽,经由挤压后,而可使铁粉形成一暂固态的半成品;第五步骤:取出,将第四步骤的半成品取出;第六步骤:烘烤,将第五步骤的半成品送至低温烘烤,而可使半成品定型;通过本发明的加工可一次成型,且可同时达到减少外罩加工与组装线圈与外罩程序,而有效提升所需的产量,进而可达降低成本与减少制作工序的目的。
The invention provides a once-forming method for manufacturing inductance capable of improving yield. The method comprises the following steps: firstly, materials preparation: a coil and iron powder are prepared; secondly, coil positioning: the coil which is prepared in the first step is positioned in a storage tank of a lower mould; thirdly, iron powder filling: the iron powder is filled in the storage tank in which the coil is positioned in the second step; fourthly, extrusion: the storage tank is extruded by a mould which is above the storage tank filled with the iron powder, and after being extruded, the iron powder becomes a semi-finished product in a temporary solid state; fifthly, taking out: the semi-finished product is taken out; sixthly, roasting: the semi-finished product is roasted at low temperature to finalize the semi-finished product. The inductance can be formed once by the manufacture method, and the required yield can be effectively improved by reducing procedures of manufacturing an outer housing and assembling the coil and the outer housing, thereby achieving the aim of lowering cost and reducing manufacture procedures.
