20120276783 | CONNECTOR HAVING LEAD PINS EXTENDING FROM BOTTOM AND SIDE SURFACES THEREOF - A connector for connecting to a printed circuit board, including a connector body and a plurality of lead pins extending from the connector body and soldered onto the printed circuit board. The lead pins extend from a region including a bottom surface of the connector body and a side surface adjacent to the bottom surface, thereby overcoming the drawbacks as encountered in prior techniques including missing and poor soldering during SMT soldering process or the connector falling off from the soldering point in use. | 11-01-2012 |
20130002436 | System and Method for Managing Solder Paste - A system and a method for managing solder paste are disclosed. The storage information of solder paste cans stored in a storage room is established, production information is accessed from a production managing system for analyzing an amount of solder paste cans in need, the solder paste cans to be used are inquired and obtained from the storage room, and the solder paste cans are delivered to the warm up room for warm up treatment. The solder paste is thus systematically managed, such that the efficacy of management is improved and labor cost is reduced. | 01-03-2013 |
20130004266 | Device for Managing Solder Paste - A device for managing solder paste includes a storage room, a warm up room, a preparing room and a central control device, wherein the storage room, the warm up room and the preparing room respectively have a transportation unit for delivering a solder paste can. There are reading devices disposed respectively at an inlet/outlet of the above rooms for reading information of the solder paste can when the solder paste can passes thereby, and the central control device updates storage information for the solder paste cans. The central control device may access production information of a production line from a production managing system, and thus analyze the mold number and amount of solder paste cans, receive the solder paste cans based on a first-in, first-out manner, and deliver the solder paste cans to the warm up room for the warm up treatment. | 01-03-2013 |

20130068822 | STENCIL FOR PRINTING SOLDER PASTE ON PRINTED CIRCUIT BOARD - A stencil for printing solder paste on a printed circuit board improves an assembly process, cuts production costs, and saves storage space. The stencil is coupled to a fixing frame having a plurality of fixing portions and a motor unit. The motor unit generates a plurality of pulling forces. The stencil includes a solder paste printing region and a plurality of fixing regions. Vias are disposed in the solder paste printing region. The directions of the pulling forces are coplanar with the solder paste printing region. The edge of the solder paste printing region extends outward to define the fixing regions. The fixing regions are movably fixed to the fixing portions and bear the pulling forces to flatten the solder paste printing region of the stencil. | 03-21-2013 |

20140308114 | DUST-PROOF FAN - An exemplary dust-proof fan includes a frame, a stator mounted in the frame and a rotor received in the frame. The rotor includes a bracket and multiple blades pivotably mounted to the bracket. The bracket includes an inner ring and an outer ring surrounding the inner ring. Each blade has an inner pole inserted into the inner ring and an outer pole inserted into the outer ring. The blades are spaced from each other to form multiple airflow passages therebetween when the dust-proof fan is in use. The blades are overlapped with each other to close the airflow passages when the dust-proof fan is not in use. | 10-16-2014 |
