Title:
FLEXIBLE CONNECTION MEMBER AND ELECTRONIC DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2020/036383
Kind Code:
A1
Abstract:
Various embodiments disclosed in the present document relate to a flexible connection member and an electronic device comprising same, the flexible connection member having an RF wiring for signal transmission formed therein, wherein an impedance of the RF wiring is prevented from being changed even when a flexible printed circuit board is bent. According to one embodiment, a connection member may be provided, the connection member comprising: a first conductive layer including a first logic wiring; and a second conductive layer in contact with the first conductive layer and including a bonding sheet layer, wherein the second conductive layer includes: a second logic wiring formed on part of the second conductive layer; and an RF wiring formed on another part of the second conductive layer, the bonding sheet layer includes: the second conductive layer adhered over the second logic wiring and the RF wiring; a first insulating layer formed between the first conductive layer and the second conductive layer; and pins formed on one side of the first conductive layer and the second conductive layer and configured to be electrically connected to connection pins of an external module, and the second conductive layer includes at least one via formed between the second logic wiring and the RF wiring so as to energize between the layers included in the second conductive layer. Such a flexible connection member may vary according to embodiments, and an electronic device comprising the flexible connection member may be provided according to various other embodiments.
