20080315402 | PRINTED CIRCUIT BOARD, MEMORY MODULE HAVING THE SAME AND FABRICATION METHOD THEREOF - A printed circuit board, a memory module having the same, and a fabrication method thereof. The printed circuit board includes an interconnection substrate on which electronic components are mounted and in which a plurality of signal lines are arranged. The signal lines are electrically coupled to the electronic components. A heat sink is disposed on one surface of the interconnection substrate to dissipate heat of the electronic components, and in which no signal lines are arranged. The printed circuit board includes a bending substrate coupling the interconnection substrate to the heat sink, and formed of a flexible material configured to be bent. | 12-25-2008 |
20110256671 | SEMICONDUCTOR MEMORY MODULE WITH REVERSE MOUNTED CHIP RESISTOR - A semiconductor memory module having a reverse mounted chip resistor, and a method of fabricating the same are provided. By reverse mounting the chip resistor on the semiconductor memory module, the resistive material is protected, thereby preventing open circuits caused by damage to the resistive material. Also, a chip-resistor connection pad of a module substrate is formed to extend higher from the module substrate than other connection pads connected to other elements. Thus, the resistive material of the chip resistor does not contact the module substrate, thereby preventing poor alignment and defective connections. | 10-20-2011 |
