Abstract:
A method of forming a semiconductor package is disclosed including disguising the test pads. Test pads are defined in the conductive pattern of the semiconductor package for allowing electrical test of the completed package. The test pads are formed in shapes such as letters or objects so that they are less recognizable as test pads.
Abstract:
Provided is a flexible substrate wherein a connection portion between the flexible substrate and an electric circuit board meets requirements of narrow wiring pitch and low resistance at the connection portion. An electric circuit structure, which has the flexible substrate and the electric circuit board to which the flexible substrate is connected, is also provided. A wiring pattern (22) is formed on a flexible base film (21), a connection terminal (25) connected electrically to an electrode terminal of another electric circuit board is arranged at an end portion of the wiring pattern (22), and the connection terminal (25) includes wide connection terminals (25b, 25c) having a terminal width extending across plural lines of the wiring pattern (22).

Abstract:
A label assembly includes a support and a label body. The label body is configured to allow a label to be attached thereto. The support includes an upright post, and a fixing portion formed at a distal end of the post opposite to the label body. The fixing portion is configured to removably attach the label assembly to a circuit board. A circuit board supporting the label assembly is further provided.
Abstract:
A cable connector includes a base formed on a circuit board, a plurality of pins extending from the base and electrically connected to the circuit board, and a signal type indicator. A plurality of through holes is defined in the signal type indicator to receive the pins, and an emblem is arranged on the signal type indicator to indicate the signal type of the cable connector. The diameter of each through hole is greater than the diameter of each pin so that the pins can pass through the through holes of the signal type indicator for mounting the signal type indicator on the base.

Abstract:
A semiconductor package circuit board has an indicator for specifying a location of a defective circuit board unit. The semiconductor package circuit board includes circuit board units arranged in an m-by-n matrix pattern. The indicator has marking areas arranged in an m-by-n matrix pattern so that the marking areas are marked in correspondence to locations of identified defective circuit board units of the circuit board units. An operator can readily put a defective mark on the indicator without any confusion. The operator or a sensor can readily recognize the defective mark. Since the indicator can be formed on the circuit board unit, the integration of the semiconductor package circuit board can be increased, and the productivity can be substantially improved. Furthermore, a pathway of the sensor can be reduced, and interferences that might occur if the sensor moves can be hindered.
Abstract:
A control panel for use with a beverage brewing device is provided. The control panel includes a circuit board and connector assembly in combination with a least one overlay. The circuit board, board includes at least one and commonly a plurality of devices which may include switches and lights. A plurality of overlays are configured for use with control areas. The control areas are analogous to switch controls or light areas which are provided on the circuit board. The overlays may have but are not required to have a one-to-one correspondence with the components on the circuit board. The multiple overlays in combination with a single circuit board allows for a many-to-one combination of overlays to circuit board. Additionally, the circuit board may be programmed to activate or deactivate selected components so that components underlying an overlay without a corresponding control area cannot be activated. Reprogramming may be done in a variety of situation and may be provided in a self programmable configuration which may include, but is not limited to and RFID device carried on at least one of the circuit board and overlay.
Abstract:
An MMC/SD core unit includes a PCBA in which all passive components and unpackaged IC chips are attached to a single side of a PCB opposite to the metal contacts. The IC chips include, for example, a controller chip and a flash memory chip, or a single-chip (combined controller/flash memory) chip. Multiple flash IC chips are optionally stacked to increase storage capacity. The IC chip(s) are attached to the PCB by wire bonding or other chip-on-board (COB) technique. The passive components are attached by conventional surface mount technology (SMT) techniques. A molded housing is then formed over the IC chips and passive components such that the device has a uniform thickness. The MMC/SD core unit is then inserted or otherwise mounted in an eternal casing to provide a finished MMC/SD device.
