Compliant bonding of beam-leaded semiconductor devices is improved by deforming a compliant member into apertures of a rigid bonding grid during a bonding process. The deformation of the compliant member provides a desired clearance around brittle body portions of the semiconductor devices so that the body portions remain undamaged during bonding. In one example, the deformation takes place during exertion of bonding force and, in another example, just prior to the exertion of the bonding force....

Compliant bonding of successive beam-lead semiconductor devices to successive metallic patterns on substrates is accomplished with a bonding apparatus that uses an indexable compliant member. A bonding head of the apparatus is provided with a single movable tip which disengages from the compliant member during indexing of the member. The movable tip engages with a portion of the compliant member that is suspended between two drive sprockets when it is desired to perform a bonding operation. The ...

This invention relates to a new ceramic-metal composite body and a method for producing the same. Particularly, a compliant layer composition is utilized for preventing the rupture of a ceramic article and/or the yielding or failure of a metal during the pouring, solidification and cooling of a molten metal which has been cast around the ceramic. A slurry composition for the compliant layer includes plaster of paris, a liquid vehicle and a filler material. The slurry composition is coated on the...

A compliant electrical connector pin has opposed convex surfaces to grip the surfaces of a hole in a circuit board, the pin having a compliant region so that the pin compresses to reduce the cross sectional area of the pin as the pin is inserted into the hole with the pin having a transition zone proximate the compliant region with the transition zone and the compliant region sufficiently interrelated so that the transition zone partially expands the hole in the circuit board before the hole in ...

A compliant pin for preferable insertion into a multi-layer backpanel is disclosed. The pin includes a wire-wrap area, a pin stop, and a connector area. Between the connector area and the stop there is located the compliant area which forms the critical function of pin support and electrical connection. The compliant area includes first and second legs spreading out to define an eye from the pin stop adjacent the wire-wrap area of the pin. Similarly, the paired legs come together at a symmetrica...

A compliant walker for humans having limited use of their legs and lower back includes an upright wheeled frame which at least partially surrounds an upright user wearing a partial body harness which is attached to the frame by means of cable compliant apparatus consisting of sets of cable segments and angle bracket members connected between opposite side members of the frame and adjacent side portions of the harness. The type of partial body harness utilized takes two forms, the first being a t...

A compliant terminal comprises a pair of legs facing each other. Each of the legs is provided with an outwardly expanded portion in the intermediate portion. The expanded portions form an elastic contact portion for compressed fitting with a through hole. The leg portion is also provided with a pair of inward projections in the boundary region between the intermediate and free end portions. The inward projections of the two legs are substantially in contact. Therefore when the legs are inserted ...

A compliant joint is provided for prosthetic and robotic devices which permits rotation in three different planes. The joint provides for the controlled use of cable under motion. Perpendicular outer mounting frames are joined by swaged cables that interlock at a center block. Ball bearings allow for the free rotation of the second mounting frame relative to the first mounting frame within a predetermined angular rotation that is controlled by two stop devices. The cables allow for compliance at...

A compliant gear which includes an inner hub portion, an outer ring gear portion, and a compliant laminate between the hub portion and the ring gear portion. The laminate includes a rigid laminar shim of generally uniform thickness sandwiched between a pair of elastomer layers of generally uniform thickness. The laminar shim and the elastomer layers extend generally parallel to the axis of rotation of the gear.
