A structure for mounting a device on a circuit board, comprising two relay substrates provided parallel to each other between the circuit board and the device, one of the relay substrates being constituted by a relay socket substrate with an array of socket pins being inserted into and supported by the relay socket substrate, each of the socket pins being soldered to a corresponding one of solder pads in the circuit board, the other relay substrate being constituted by a relay pin substrate with an array of relay pins, for connection to the device, being inserted into and supported by the relay pin substrate, each of the relay pins being soldered to a corresponding one of solder balls provided in the device, the relay pins, in the relay pin substrate, each in its one end opposite to the soldered end being detachably fitted in the socket pins each in its one end on the socket side. This construction enables repair and replacement of the device and the evaluation and tests of the performance of the device.

Structure for mounting device on circuit board

A printed circuit board connector is formed by a fixed base portion (4) that is provided in a fixed manner onto a printed circuit board (1) and a movable base portion (5) that can be mated as one with the fixed base portion (4) in either of two (or three) different directions with respect to the fixed base portion, these directions differing from each other by 90 degrees. A cable-side connector (3) can be connected to the movable fixed base portion 5. By changing the direction of mating of the movable base portion with respect to the fixed base portion, it is possible to change the direction (compare FIGS. 3 and 4) of connection of the cable-side connector with respect to the fixed base portion. This enables the change of the connection direction of the cable with respect to the printed circuit board. This also enables the direction of connection of a cable-side connector with respect to the printed circuit board to be changed while using one and the same board-side connector, thereby enabling a reduction in the number of components required for printed circuit hardware, while achieving universality and sharing of connectors.
