Abstract: This disclosure discloses an optical sensing device. The device includes a carrier body; a first light-emitting device disposed on the carrier body; and a light-receiving device including a group III-V semiconductor material disposed on the carrier body, including a light-receiving surface having an area, wherein the light-receiving device is capable of receiving a first received wavelength having a largest external quantum efficiency so the ratio of the largest external quantum efficiency to the area is ?13.

Abstract: A rail-type organic light emitting diode lamp assembly is provided. The lamp assembly includes a lamp module, an annular member, a connector, a conductive member, and a rail module. The annular member includes a protrusion portion having a pair of indentations. The connector is connected to the annular member, and includes a through hole, a first end provided with a pair of ears and a second end provided with a pair of hooks. The conductive member is provided in the through hole and has a first end in contact with the annular conductive coil. The rail module is connected with the connector and includes a conductor in contact with a second end of the conductive member. The connector can be slidably hooked to the rail module through the hooks, and after the ears are inserted into the indentations, the annular member can be rotatable with respect to the connector.

Abstract: The present invention provides an encapsulated device with heat isolating structure and a reflow soldering method thereof. The encapsulated device has a micro heat spreader with vapor chamber formed on the surface, and a cover covers the encapsulated device and wraps the micro heat spreader. A hermetical space is formed to isolate the high temperature when forming the solder balls and performing the SMT process, and prevent the micro heat spreader from being damaged. The present invention can provide an encapsulated device with heat isolating structure and a reflow soldering method thereof to protect the product in the reflow soldering process and improve the yield, and the cover can be reused to lower the cost.

Abstract: A system-in-a-package device installs a second surface of an integrated passive devices (IPD) substrate onto a bearing substrate to achieve electric connection. At least an active device is then installed on a first surface of the IPD substrate by means of flip chip or wire bonding to achieve electric connection. Next, an encapsulant is formed to at least cover the active device or its contacts with the IPD substrate for protection. The system-in-a-package device uses conducting holes of the bearing substrate as contacts with the exterior. Thereby, more functions can be directly integrated into the same package to have the advantages of small package size, increased efficiency, and fast fabrication speed.

Abstract: A flat plate mold with special treatment or a metallic flat plate mold is adopted to flatten the resin painted over on IC chips during package dispensing process, such that it is able to maintain a consistent flatness of the surface of IC products after dispensing for laser or ink marking. And heat sinks can be attached to the flat plate mold to increase the heat-dissipating rate of IC products after dispensing.
