Title:
METHOD FOR MANUFACTURING UNIT ON WHICH LED IS MOUNTED, LED SOCKET, AND ELECTRONIC CIRCUIT SUBSTRATE FOR MOUNTING LED
Document Type and Number:
WIPO Patent Application WO/2006/033297
Kind Code:
A1
Abstract:
It is possible to improve the workability when mounting an LED on an electronic circuit substrate by eliminating thermal damage and mechanical damage. Insulation resin for mechanically connecting a plurality of flexible metal conductors is used as an insulation body for defining a socket which can be shared by a cannonball type LED and a chip type LED having a pair of lead lines which are substantially parallel to each other. A flexible conductor substrate having a built-in socket is formed as a unitary block. The cannonball type LED or the chip type LED is engaged with the socket and electric connection is completed. By abolishing the thermal treatment, it is possible to prevent a thermal damage. The electrodes of the cannonball type LED and the chip type LED are engaged with and fixed to the socket electrode so than no external force is applied to a portion between the lead line of the cannonball type LED and the LED, thereby improving workability. Moreover, in the case of the chip type LED, when the chip type LED is engaged with the socket, an engagement claw automatically presses a part of the top of the chip type LED. Accordingly, no cap-type pressing part is required. This also improves workability.
