摘要:
An integrated circuit chip (903), which has a plurality of pads (903b) and non-reflowable contact members (1201) to be connected by reflow attachment to external parts. Each of these contact members (1201) has a height-to-diameter ratio and uniform diameter favorable for absorbing strain under thermomechanical stress. The members have a solderable surface (1202) on each end and a layer of reflowable material on each end. Each member is solder-attached (1204) at one end to a chip contact pad (903b), while the other end (1203) of each member is operable for reflow attachment to external parts.
