Abstract
The invention relates to a printed circuit board structure, which comprises a first body, a second body and a sleeve. The sleeve is arranged between and connected with the first body and the second body so as to generate a differential height between the first body and the second body. Via the differential height are solved the problems of insufficient probe stiffness and poor wafer-sort quality, which is caused by decreasing the probe diameter to adapt to miniaturized chips.
