Abstract
There is provided a manufacturing method of producing a non-reciprocal circuit device, which is much smaller than a conventional counterpart, with excellent mass productivity. A support substrate 400 having support portions Q11 to Qnm arranged therein in a lattice-like form is produced, and a previously manufactured gyromagnetic component 1 is bonded on each of the support portion Q11 to Qnm. Then, a permanent magnet plate 200 is bonded. The permanent magnet plate 200 has a plane area which covers all the gyromagnetic components 1. Subsequently, the entire structure is cut along lines X1-X1 and lines Y1-Y1 in accordance with each gyromagnetic component 1.
Claims2
A manufacturing method of a non-reciprocal circuit device comprising steps of:
- arranging gyromagnetic components on one surface of a support substrate including many support portions for non-reciprocal circuit devices arranged in a lattice-like form therein in accordance with each of the support portions;
- arranging a permanent magnet plate on the gyromagnetic components, the permanent magnet plate having a plane area which covers all the gyromagnetic components;
- and
- cutting the entire structure along boundaries of the respective gyromagnetic components and support portions to take out each assembly including a support substrate, the gyromagnetic component and a permanent magnet.
A manufacturing method of a non-reciprocal circuit device comprising steps of:
- superimposing a gyromagnetic component aggregate including many gyromagnetic component elements corresponding to support portions arranged therein in a lattice-like form on a support substrate including many support portions for non-reciprocal circuit devices arranged therein in a lattice-like form;
- arranging a permanent magnet plate on the gyromagnetic component aggregate;
- and
- cutting the entire structure along boundaries of the respective gyromagnetic component elements and support portions to take out each assembly including a support substrate, a gyromagnetic component and a permanent magnet.
