Abstract: A test method for a semiconductor device includes: loading a test tray having semiconductor devices of first and second lots arranged thereon into a test chamber; storing lot information of each of the semiconductor devices; performing a test program on each of the semiconductor devices; obtaining ID information of each of the semiconductor devices; matching the ID information with the lot information to generate lot sorting information; and sorting the semiconductor devices based on results of the test program and the lot sorting information.

Abstract: A manufacturing method for a printed circuit board includes: transferring roughness of a metal film to an insulating layer by laminating the metal film on the insulating layer, the metal film having the roughness formed on one surface thereof and having a discrete metal layer laminated thereon; exposing a surface of the insulating layer, on which the roughness is transferred, by removing the metal film; processing the surface of the insulating layer having the roughness formed thereon with an acidic solution; and forming a circuit pattern on the insulating layer by a plating process.

Abstract: A mobile terminal including a function key configured to select at least one of a first list of menu items and a second list of menu items, a selecting key configured to select a function from at least one of the first menu list and the second menu list, and a display configured to display at least one of the selected first list of menu items, the selected second list of menu items and the selected function. Further, the first list of menu items and the selected function are selectively displayed on a first display portion of the terminal, and the second list of the menu items is displayed on a second display portion of the terminal. The terminal also includes a controller configured to activate the function selected by the selecting key. In addition, when the activated function displayed on the first display portion is a screen occupation function which is not to be interrupted, the first display portion does not display the list of first menu items when the function key is selected.

Abstract: A mobile terminal and a screen changing method in the mobile terminal are discussed. The method in one embodiment includes selecting a function key on the mobile terminal, determining a type of the selected function key, and changing a current process displayed on one of a first and second display portions of a display of the mobile terminal according to the type of the function key determined in the determining step.

Abstract: A mobile terminal and an apparatus and method for processing an alert message of a mobile communication terminal, are discussed. The apparatus includes at least one module for generating at least one alert message and outputting the generated alert message, and a controller for selectively displaying the outputted alert message on a second display unit according to a type of a task being executed on a first display unit.

Abstract: A method for managing resources in a mobile terminal includes determining whether or not a required resource is available to perform a requested task on the mobile terminal and selectively performing the requested task based on whether or not the required resource is available.

Abstract: A method of testing a semiconductor device, which can reduce a period of time for testing a packaged semiconductor chip. First, semiconductor chips to be tested are classified in a lot unit. The semiconductor chips are fist tested in units of lots. The defective semiconductor chips among the semiconductor chips of a predetermined number of lots that are first time tested are collectively retested. First test data regarding the semiconductor chips may be classified and stored for each respective lot. Retest data regarding the semiconductor chips may be classified and stored for each respective lot. Test data regarding the semiconductor chips may be classified and stored into first test data and retest data for each respective lot.

Abstract: Disclosed is an aqueous alloy plating solution for surface treatment of a modular PCB. The plating solution comprises 1-30 wt % of an organic acid having at least one sulfonic acid group (—SO3H), 0.1-20 wt % of a complexing agent, 0.1-15 wt % of a thio-compound having at least one —S—, 0.05-5 wt % of a water soluble gold compound, 0.001-1 wt % of a water soluble silver compound and 0.1-10 wt % of a sequestering agent, based upon the weight of the plating solution. According to this invention, all plating properties required for the modular PCB are obtained through a single plating process, instead of the conventional double plating process.
