    摘要: The present invention comprises cost-effectively manufactured, electrically conductive and mechanically compliant micro-leads and a method of utilizing these compliant micro-leads to interconnect area grid array chip scale packages (“CSPs”) to printed wiring boards (“PWBs”). The preferred method includes orienting a plurality of conductive compliant micro-leads, secured to one another in parallel with tie bars and tooling, to align with a corresponding pattern of conductive pads located along the surface of an area grid array CSP. The compliant micro-leads are electrically connected and mechanically secured to the corresponding connecting surfaces of the area grid array CSP. Next, the securing tie bars and the tooling are removed. The opposite ends of the conductive compliant micro-leads are then oriented to align with a corresponding pattern of conductive surface pads on a PWB. The opposite end of each compliant micro-lead is then electrically connected and mechanically secured to its corresponding connecting pad located on the surface of the PWB, thereby establishing a compliant electrical connection between the area grid array CSP and the PWB. An alternative embodiment of the present invention utilizes an area grid array interposer with compliant micro-leads to provide additional compliancy.

    摘要: The invention provides an apparatus and method for positioning solder balls in a desired array on a substrate. A positioning means is provided for positioning the solder balls in positions corresponding to the array of positions the solder balls are to take up on the substrate. A container for receiving a plurality of solder balls and which is movable between a first position remote from the positioning means and a second position directly thereover supplies solder balls to the positioning means. Means are provided to bias the solder balls in the direction of movement of the container from the first to the second position whereby to reduce or obviate damage to the solder balls during such movement.
