Semiconductor device and its manufacturing method

A film circuit connector in which respective conductive tracks in film contact areas on front, mating faces are pressed together into electrical connection between side walls of a metal channel-section receptacle spring and a compressible elastomeric plug spring which engage respective rear faces of the films, the compressible plug spring providing a counter-force to the receptacle spring force, accommodating any variations in receptacle spring force arising longitudinally thereof, ensuring constant contact force between all tracks. Tabs for anchoring and grounding the receptacle spring to the circuit board are struck out and bent down from opposite walls of the receptacle spring, enabling electrical shielding of contact areas. Linking portions of conductive tracks connecting the mating contact portions on the front face of the film to board connecting portions, are formed on the rear face of the film for electrical and mechanical protection and may be insulated on all sides. The film is formed with windows for exposing conductive tracks for connection to a circuit board and pockets for trapping board mounted solder pads for connection to the conductive tracks. Film positioning and clamping members in the receptacle locate end film portions inwardly minimizing occupation of board space.

A device for mounting a flat package on a circuit board, comprises a rectangular base frame attached to the circuit board, a rectangular clamping frame and a cover frame for releasable locking engagement with the base frame for retaining the clamping frame in pressing engagement with a flat package mounted on the circuit board within the base frame. The clamping frame has recesses formed in respective corners and lands forming stop surfaces with elastic strip locating grooves formed on opposite sides thereof. Further elastic strip locating grooves and elastic strip anchoring grooves of constricted cross-sectional size, extend along a lower, clamping face and on the undersides of the lugs. The base frame has contact guiding wall surfaces extending downwardly and inwardly from respective corners thereof for retaining the flat package contacts in precise alignment with respect pads of the circuit board.

A film circuit connector assembly comprises matable housing assemblies each including an outer insulating housing receiving a film circuit supporting member carrying a film circuit with a mating contact area therein extending away from a mating face along a film circuit supporting wall with a circuit board engaging area of the film circuit extending out from a base of the housing assembly. A cylindrical spring is mounted in a recess extending along at least one film supporting wall in engagement with a rear face of a contact area pressing the contact areas of the mating connectors together. In one example, the housing assembly clamps free ends of the film circuit conductors in resiliently deformed condition into engagement with the circuit board. Apertures may be formed through the insulating web of the circuit board engaging area exposing conductive tracks thereof at locations corresponding to respective reflow solder pads of a circuit board and forming pockets receiving and confining the reflowing solder therein to avoid solder bridges being formed between adjacent tracks.

Respective opposite ends of an insulating housing body of a surface mount connector are integrally formed with pairs of opposed, resilient, L-shaped arms, aligned with respective recesses extending under a board engaging face and embracing respective anchoring portions of respective retaining plates with a solder tab of each retaining plate received in a respective recess. Free ends of the arms extend towards each other in spaced apart relation defining between them an inspection window through which a reflow solder join between the solder tab and a dummy pad on the circuit board can be seen and checked from above the board.

In an IC connector for connecting lead terminals of an IC package of the dual in-line type to terminals of a circuit board, first grooves and first projections are formed on two surfaces of a slide body. The main body has two walls each of which has a surface which has a plurality of second grooves and which opposes at least one surface of the slide body. One end of each connecting terminal is inserted in each second groove. The other end of each connecting terminal extends through each second groove to be connected to a predetermined terminal of the circuit board. The slide body is supported by a supporting means such that the slide body may be movable between a first position and a second position along the direction of arrangement of the second grooves. When the slide body is in the first position, the first and second grooves define gaps therebetween into which or from which the lead terminals may be inserted or removed. When the slide body is in the second position, the second grooves and first projections oppose each other so that the first projections urge the connecting terminals against the second grooves against the elastic force of the connecting terminals. When the lead terminals are inserted in the second grooves, the connecting terminals and the lead terminals are urged against each other.
