A method of precisely positioning a quantity of conductive spacers (e.g., spherically shaped solder balls) on respective conductive pads (e.g., copper pads) of an underlying substrate (e.g., an FR4 printed circuit board or flexible circuit member) wherein the spacers are forcibly retained within a suitable holder and, when engaged with the respective pads, reflowed to effect a plurality of positive electrical connections between the spacers and pads. Such forcible retention allows for partial extension of the spacers from the invention's carrier, which is also disclosed.

Method of making an electronic package having spacer elements

An electronic apparatus (for example, a portable computer) which includes two portions (for example a display and a keyboard) which are connected, electrically, by a flexible cable. The apparatus provides a unique coupling scheme wherein a movable member is used which moves (for example, rotationally) on at least a part of each of the two portions in a manner substantially independent of the motion of such parts. The flexible cable passes through this member (through opposite openings in the sides thereof) and, significantly, engages the member during movement (pivotal) of one/both of the two portions to assist in effecting the member's rotation. Such movement is attained without harm to the cable, while assuring a compact design for the final product incorporating the coupling structure.
