Abstract
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.
