Patent ID: 8007626

Claim:
A method of bonding a capillary tube made of polytetrafluoroethylene or other suitable thermally deformable material to a port in a glass wafer comprising the steps of: treating a surface of the capillary tube to render said surface bondable and wettable by a conventional epoxy resin; inserting a support inside said capillary to prevent inward deformation of said capillary during subsequent fabricating steps; inserting said supported capillary inside said port on said wafer; heating an end of said capillary proximate a bottom portion of said port to effect melting of a portion of said heated end of said capillary; moving said melted end of said capillary into contact with a wall of said port at a desired location for said capillary in said port, thus forming a temporary seal between said capillary and said wall of said port; and introducing an epoxy around said capillary to bind said capillary to said wafer.
