Abstract
The ball grid array package (10) uses a flexible base (30) having a substantially flat center plate (34) disposed at a first level coupled to a substantially flat base plate (32) disposed at a second level. The center plate (34) is coupled to the base plate (32) by a plurality of flexible narrow straps (36-38) arranged substantially surrounding the center plate (34). The flexible base (30) accommodates the thermal expansion in the pedestal (18) caused by the powered up integrated circuit (16) so that the rest of the package does not expand and induce stress in the solder joint between the ball grid array (12) and the printed circuit board (14).
