The assembly of the stainless steel feedthrough box for the CC cryostat resulted in distortion of the slotted plates through which the circuit boards must be installed. Due to the o-ring grooves in the plates and the presence of small pump out passages it is difficult to machine the surface flat after installation. Installing the boards on the distorted surface requires distorting the g-10 flange and the board which is glued to it to match the surface distortion and achieve a seal. This results in stresses for which the epoxy bond may not be adequate. The purpose of this work is to estimate the shear and normal stresses in the two critical planes between the board and flange and evaluate epoxy joint performance
