description abstract	Abstract: During fabrication of the TIROS-N Microwave Sounding Unit, connector cleaning fluids penetrated to the interior of the chassis. This caused severe swelling of the conformal coating material and the subsequent fracture of electronic components, dissolution of polyurethane insulation on the magnet hookup wire, and removal of component identification markings. To preclude detrimental results, care should be exercised in the selection of fluids to be used with or in the presence of polymeric and elastomeric materials.
