Circuit module and method for mounting the same
First Claim
Patent Images
1. A circuit module comprising:
- a covering member which has a plate portion and at least one supporting portion; and
a multi-layer circuit board having electric wires between layers;
a transformer including coils, which are defined by coil patterns disposed in the multi-layer circuit board, and cores, which form magnetic paths by one or more leg portions of the cores being disposed in through holes of the circuit board positioned at a center and in a surrounding region of the coils;
wherein the at least one supporting portion fixes the plate portion in parallel to the surface of the circuit board, the covering member is defined by a portion of the at least one supporting portion extending from the plate portion in the direction perpendicular to the plate portion, the at least one supporting portion is provided with attaching portions at distal ends, and the attaching portions are engaged with the through holes in the circuit board.

Abstract
A circuit module has a circuit board on which electronic components are mounted and a covering member which has a plate portion and one or more supporting portions. The supporting portions fix the plate portion parallel to the surface of the circuit board. The covering member can be chucked by a chucking device to mount the circuit module to a mother circuit board.

8. A circuit module having a multi-layer circuit board on on which a transformer is disposed and on which at least one electronic component other than the transformer is mounted, the transformer including coils which are defined by coil patterns disposed in the multi-layer circuit board, at least one through hole which is drilled in the multi-layer circuit board at a center and in the surrounding region of the coils, and cores forming magnetic paths by one or more leg portions being disposed in the at least one through hole, the circuit module comprising:
-
a covering member which a has plate portion and at least one supporting portion;
wherein the at least one supporting portion is engaged with the at least one through hole so as to arrange the plate portion to be parallel to the multi-layer circuit board. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 21, 22)
