METHOD FOR MANUFACTURING CHIP INDUCTOR BY PLATING CERAMIC ALUMINA CORE WITH COPPER

摘要

PURPOSE: A method is provided to allow for mass production of chip inductors having high inductances and quality by plating a ceramic alumina core with copper and processing circuit through the use of a laser. CONSTITUTION: A method comprises a step of mounting a metal pattern made of alumina powder to a press, and forming a form having a predetermined size; a step of forming a ceramic alumina core having a coil portion(11) and an electrode portion(12) by sintering the form at a predetermined temperature and grinding the form; a step of etching the surface of the core; a step of performing an electroless copper plating on the surface of the ceramic alumina core; and a step of forming a chip conductor by processing grooves at the copper plated coil through the use of a laser.
