Title:
HIGH-FREQUENCY MODULE
Document Type and Number:
WIPO Patent Application WO/2021/033418
Kind Code:
A1
Abstract:
The purpose of the present invention is to reduce the stress applied to an electronic component when mounting a high-frequency module on an outer substrate, while preventing the electronic component from peeling from a mounting substrate. A mounting substrate (2) has one major surface (first major surface 21). An electronic component (3) has a first surface (31), a second surface (32), and a side surface (33), and is provided on the one major surface of the mounting substrate (2). A solder bump (5) is disposed between the mounting substrate (2) and the electronic component (3), and electrically connects the mounting substrate (2) and the electronic component (3) to each other. A resin layer (7) is provided on the one major surface of the mounting substrate (2) so as to cover the electronic component (3). The first surface (31) is a surface of the electronic component (3) opposite the mounting substrate (2). The side surface (33) of the electronic component (3) is in contact with the resin layer (7). In a thickness direction (D1) of the mounting substrate (2), a space (10) is provided between at least a part of the first surface (31) and the resin layer (7).
