20130009294 | MULTI-CHIP PACKAGE HAVING LEADERFRAME-TYPE CONTACT FINGERS - Disclosed is a multi-chip package having leadframe-type contact fingers, primarily comprising a leadframe, a non-conductive tape, a first chip and a second chip disposed on the first chip. The leadframe includes a die paddle on which the first chip is disposed and a plurality of first contact fingers, moreover, at least a second contact finger is integrally extended from the die paddle and is located among the first contact fingers so that the first and second contact fingers are arranged in a row. The non-conductive tape is attached onto the first and second contact fingers conforming to the arranging row of the first contact fingers so that the second contact finger is mechanically fastened with the first contact fingers. An encapsulant encapsulates the first chip, the second chip and the non-conductive tape with a plated metal layer formed on the bottom surfaces of the first and second contact fingers and exposed from the encapsulant. Accordingly, delamination of the conventional substrate or a die paddle can be avoided and the amount of tie bars used can be decreased. | 01-10-2013 |

20130069223 | FLASH MEMORY CARD WITHOUT A SUBSTRATE AND ITS FABRICATION METHOD - Disclosed is a flash memory card without a substrate, primarily comprising a memory chip component, a controller chip disposed on the memory chip, and an encapsulant encapsulating both chips. Formed on an active surface and a back surface of the memory chip component are a first RDL (redistribution layer) and a second RDL respectively. A plurality of TSVs (through silicon vias) penetrate from the active surface to the back surface to electrically connect both RDLs. A plurality of contacting fingers are disposed on the back surface of the memory chip component and electrically connected with the second RDL. Additionally, the encapsulant has a card appearance with one surface of each contacting finger to be exposed. Accordingly, the flash memory card can save conventional substrate structure with better reliability and efficiency for packaging processes. | 03-21-2013 |

20090184814 | Wireless tire pressure monitoring system with interactive multiple frequency channel - A wireless tire pressure monitoring system with interactive multiple frequency channel includes a controlling host module and multiple tire detection units. The controlling host module includes a first CPU, a key unit, a display unit, a low-frequency wireless transmitter, and a high-frequency wireless receiver. The tire detection units are separately provided on tires of a vehicle and each include a second CPU, a tire information detecting device, a low-frequency wireless receiver, and a high-frequency wireless transmitter. A default standard value may be set via the key unit. The low-frequency wireless transmitter transmits a low-frequency signal to each of the low-frequency wireless receivers for requesting the tire detection units to transmit current tire information, which is then sent via a high-frequency signal transmitted by the high-frequency wireless transmitter to the high-frequency wireless receiver. | 07-23-2009 |
