Abstract: Process for shaping conductors critically spaced on a carrier that are bonded to contact locations on a substrate surface. The conductors are cantilevered with each adjacent conductor bonded to a contact location that is a different distance from the carrier. Each conductor remains in the plane of the support of the carrier to the vicinity of its respective contact location where it is shaped to extend nearly vertically toward the substrate then horizontally across the contact location exerting pressure on the contact location.

Abstract: In order to reemploy the centering strips when equipping wiring backplanes with contact blades, the contact blades (2, 12) have their press-in zones introduced into a blade holder (1, 11) serving as a centering strip, being introduced thereinto in attitudinally correct allocation to one another. The contact blades (2, 12) introduced into the blade holder (1, 11) are pressed into the wiring backplane (5, 15) from the blade holder (1, 11) with a press-in die (7, 17) and the blade holder (1, 11) is pulled off from the contact blades (2, 12) when the press-in die (7, 17) is retracted.

Abstract: For soldering a terminal (14) to a land (13) formed on an FPC (12) made of a material having a softening point below 230.degree. C., such as PET, by using a flow soldering or reflow soldering technique, an opening (17) larger than the land (13) is formed in a thermal insulation holder (11) including a phenolic paper base copper clad laminate board or the like so that the land (13) and the terminal (14) are within sight, and the thermal insulation holder (11) is held in contact with a surface of the FPC (12) to which solder is applied so that the land (13) and the terminal (14) are located within the opening (17) to perform the soldering using the flow soldering or reflow soldering technique, whereby molten solder readily reaches the land (13) through the opening (17) which need not be worked into a conventional trapezoidal configuration in vertical section, thereby preventing poor soldering.

Abstract: Disclosed is a modular jack having a first plurality of wires which extend in a common vertical plane from the bottom wall of the housing across the opened end and to the top wall and then extend horizontally forward and then angularly downwardly and rearwardly back toward the rear opened end. A second plurality of wires extends first in a common vertical plane from the bottom wall across only a part of the rear opened end and then extends obliquely, horizontally and upwardly toward the front opened end.

Abstract: A crimp terminal is supplied to a predetermined crimping position. Into the barrel of the supplied terminal, the wire end of an insulated conductor is inserted. At that time, the cable conductor end is aligned in the desired proper position for crimping. Even when the cable conductor end is deformed or broken in the stripping or supply processes, all the cable conductor ends can be reliably accommodated in the barrel of the terminal. Accordingly, it is possible to prevent crimping defects caused by exclusion from the terminal of one or more wire ends.

Abstract: A mold is provided for use in encapsulating integrated circuit (IC) dies attached to die attach pads of lead frames, wherein the mold has one or more support elements in cavities of the mold for supporting the die attach pad portions of the lead frame while the mold is closed on the lead frame and encapsulation material is injected to encapsulate the IC dies and die attach pads. The support elements are, in a preferred embodiment, pins extending from the surfaces of the cavities in the mold, and the pins keep the die attach pads from moving into contact with surfaces of the cavities, so die attach pads or dies are not exposed in finished packages. In a preferred embodiment the pins each are tapered in the extended portion, so the amount of exposure of the die attach pad is absolutely minimized. In another embodiment, the support elements are retractable.
