Abstract:
The invention relates to a method for removing from a carrier a carrier part with a housing arranged thereon, characterized in that prior to performing the separating operation a notched line is arranged in the carrier on at least one side of the carrier along at least a part of the length of a separating edge to be arranged. The invention also relates to a carrier part with a housing arranged thereon, which carrier part contains openings on the side of the carrier remote from the housing which are filled with encapsulating material, manufactured with the present method. The invention moreover relates to an apparatus for performing the method.
Abstract:
A process and an apparatus for manufacturing semiconductor devices. The semiconductor devices comprise a carrier on which a die is mounted. During a stamping process a shaft is rotated and a plunger with a stamping tool are moved in the stamping direction in a reciprocating manner. When the stamping tool is lifted, a strip comprising semiconductor devices is moved such that a semiconductor device is positioned under the stamping tool. Subsequently the stamping tool is lowered whereby the leads are cut loose from the strip and are bent into an appropriate shape.

The system (100) includes: at least one machine (101) which is used in the manufacturing or testing process; at least one sensing device (115), coupled to the at least one machine (101), for measuring a process parameter associated with the at least one machine (101); and a controller (DNM), coupled to the at least one sensing device (115), for receiving and storing measured data from the at least one sensing device (115). The method includes the acts of: measuring a value of a process parameter associated with a machine (101) used in the manufacturing or testing process; converting the measured value of the process parameter into a digital data signal having a specified data format; transmitting the digital data signal to a controller (DNM); and storing the digital data signal in a database.
Abstract:
A lightweight, economical, reliable and adaptable tool (100) for use in joining wire connector assemblies such as those utilized in telecommunications includes a base member (102) including a housing (118) and a cam mechanism (400) with a T-bar (114) pivotally connected with a cam mechanism (400). Removable wire connector holders (200) are provided which can be interchanged on the base member (204) and force applicators (200 and 320) for use with particular wire connectors can be applied to the T-bar (114). By providing interchangeability for the wire connector holders (200) and the force applicators (220 and 320) the disclosed tool (100) is capable of being utilized with a variety of industry standard wire connector assemblies without requiring multiple tools. In addition, the tool (100) is formed utilizing a simplified construction and is made from materials which reduce the weight, increase the reliability and reduce the cost thereof.
Abstract:
Methods and apparatus for facilitating the use of existing onsertion machines (50) by trimming and sequencing a plurality of components to be onserted on an as-needed basis from components of generic values obtained from the manufacturer and providing the sequence of components to a single pick-up (30) point on the onsertion machine. Post-encapsulation trimming of these components by laser (222) also results in novel components of high precision.
Abstract:
A modular connector press (20) for terminating different types of connectors (40) to a flat cable (22) includes left and right cable tray assemblies (48, 49) that are mounted for accurately positioning and laterally translating the cable in a first direction transverse to the axial direction of the cable between a loading position for initial positioning of the cable and a termination position where the cable is positioned beneath a press ram (21). Each tray assembly (48, 49) includes a main body (54), a cable tray (55) and means for mounting the cable tray (55) to the main body (54) to allow adjustable translation of the cable tray in a second direction transverse to the first direction of translation of the tray assembly means. Each cable tray (55) includes a plurality of connector positioning slots (61) allowing the accurate positioning of terminated connectors of a harness on each cable tray. The left and right tray assemblies (48, 49) can be fastened together to form a two tray unit, each tray of which, with respect to the ram of the press, can be accurately and relatively positioned in the second direction allowing the accurate positioning and termination of a third connector therebetween. The modular press (20) also includes a plurality of different types of interchangeable connector test heads (26) allowing the press to be easily modified to terminate and test a variety of different connectors to a connector harness.
Abstract:
A component lead cutting and forming apparatus for axial lead electronic components respectively having first and second leads secured to tape, including bending dies for supporting the first and second leads of an axial lead component in process. The bending dies (121) are supported by slide blocks (125), and strain relief clamps (133) selectively clamp the first and second leads against the bending dies. First and second parallel carriage blocks (129), which are adjustable in separation, support the slide blocks. Driving apparatus including an air cylinder translates the slide blocks between a first position and a second position in a linear direction generally orthogonal to the orientation of the axial leads of the component in process, and further controls cutting blades (149) for cutting the leads of the component in process. The cutting blades are secured in parallel cutting blade support blocks (151) which are adjustable as to separation. Bending rollers (143) supported by the carriage blocks cooperate with the bending dies to bend the leads of the axial lead component in process as the slide blocks are linearly translated from the first position to the second position. When the slide blocks are in the second position, grippers (211, 213) grasp the processed component legs and translate the component for robotic pick-up presentation.
Abstract:
A piezoelectric element (1) is mounted to a clinch lever (144) for detecting stress-strain generated therein when cutting and clinching leads (100a) of an electronic component (100) that has been inserted in corresponding holes (102a) formed in a circuit board substrate (102). A detected voltage d is compared to a threshold voltage s selected from a plurality of threshold voltages preset in the device. When the detected voltage d exceeds the threshold voltage s, the insertion detecting section outputs a signal indicating that the insertion of the leads in the holes has been performed normally.
