Title:
ELECTRONIC COMPONENT MOUNTING STRUCTURE, ELECTRONIC COMPONENT MOUNTING METHOD, AND LED DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2021/010079
Kind Code:
A1
Abstract:
The present invention pertains to an electronic component mounting structure for mounting chip-type LED chips 3 on one surface of a wiring substrate 1. The LED chips 3 are each provided with a pair of electrode parts 30 each having a recess in the surface thereof. The wiring substrate 1 is provided with: salient bump electrodes 4 which are connected to the respective recesses of the electrode parts 30; and fixing members 2, the position of which is determined in accordance with the arrangement of said bump electrodes 4 and which is for fixing the LED chips 3. The bump electrodes 4 are joined face-to-face with the respective recesses of the electrode parts. The LED chips 3 are fixed to the wiring substrate 1 via the fixing members 2. With this configuration, it is possible to improve the mounting yield of the LED chips 3.
