Patent number: 9748460Abstract: An LED device and method of manufacture including separately coupling a thin flexible interposer and an LED die to a heat sink structure and then electrically coupling the interposer and the LED die together with a wirebond. A specifically shaped perimeter of an aperture within the interposer negates the need for a cavity or alignment markings within the heat sink structure by limiting the orientation in which the die fits within the aperture. Alternatively, an LED device and method of manufacture include coupling a rigid circuit board to an LED die such that electrical contacts of the die are electrically coupled with electrical input/output terminals of the circuit board. This die/board unit is then able to be coupled to a heat sink structure to form a portion of the device.Type: GrantFiled: February 27, 2014Date of Patent: August 29, 2017Assignee: Flextronics AP, LLCInventors: Samuel Tam, Murad Kurwa, Shing Dick Pang Tak

Patent number: 9554465Abstract: A stretchable interconnect includes a plurality of electrically conductive traces formed as a complex pattern on an elastic substrate. The form of the electrically conductive traces is such that when the elastic substrate is in a relaxed, or non-stretched, state each of the electrically conductive traces forms a tortuous path, such as a waveform, along the elastic substrate. The tortuous path of the electrically conductive traces provides slack such that as the elastic substrate is stretched the slack is taken up. Once released, the elastic substrate moves from the stretched position to the relaxed, non-stretched position, and slack is reintroduced into the electrically conductive traces in the form of the original tortuous path.Type: GrantFiled: January 9, 2015Date of Patent: January 24, 2017Assignee: Flextronics AP, LLCInventors: Weifeng Liu, Anwar Mohammed, Dick Pang, Murad Kurwa

Patent number: 9018749Abstract: Described herein is a stacked package using laser direct structuring. The stacked package includes a die attached to a substrate. The die is encapsulated with a laser direct structuring mold material. The laser direct structuring mold material is laser activated to form circuit traces on the top and side surfaces of the laser direct structuring mold material. The circuit traces then undergo metallization. A package is then attached to the metalized circuit traces and is electrically connected to the substrate via the metalized circuit traces.Type: GrantFiled: January 2, 2014Date of Patent: April 28, 2015Assignee: Flextronics AP, LLCInventors: Samuel Tam, Bryan Lee Sik Pong, Dick Pang
