Title:
ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/217321
Kind Code:
A1
Abstract:
An electric device (1) includes: a circuit substrate (10); a heat sink (20); a first connection part (22) electrically connecting the heat sink (20) with the circuit substrate (10); a second connection part (21) electrically connecting the heat sink (20) with an electroconductive frame by coming into contact with the electroconductive frame. The circuit substrate (10) is provided with: a frame ground pattern electrically connected to the heat sink (20) via the first connection part (22); a signal ground pattern constituting a return path which forms a pair with a wiring between the first connector (11) and an electronic component; and a circuit element (12) electrically connecting the frame ground pattern with the signal ground pattern. The first connector (11), the circuit element (12), the first connection part (22), and the second connection part (21) are aligned along an edge of the circuit substrate (10).
