Tensile (?) Strength of PCB SMT pad | 16 February, 2015

Could anyone point me in the direction of finding out how much strength an SMT pad has in relation to being pulled away from the substrate/laminate? We are in process of trying to build a 6mil thick board and want to know if a chip can be placed onto this small thickness board without the worry of the pad coming off under certain circumstances.

Material: Fr4 Copper weight: 1oz finished Thickness: .006"
