Abstract: A heat transfer pad includes a bladder and a pad port. The bladder has an outside perimeter, an inner face and an outer face enclosing a bladder interior. The pad port has a tubing segment with a proximal end which extends through the outside perimeter of the bladder into the bladder interior. A port seal is formed by bonding the inner and outer faces of the bladder to the proximal end of the tubing segment at a port bond point distal to the outside perimeter of the bladder in the bladder interior. The proximal end of the tubing segment is maintained unbonded to the inner and outer faces of the bladder between the port seal and the outside perimeter of the bladder, thereby defining a strain relief section of the bladder which resists occlusion of the pad port.

Abstract: A process control procedure for a bonding process includes predetermining a deformation limit and a deforming time limit is for deforming a bonding precursor member. The bonding precursor member is deformed while monitoring instantaneous deformation values and instantaneous deforming time values for the bonding precursor member. A deforming shut-down time value is set at an instantaneous deforming time value corresponding to an occurrence of a first condition or a second condition. The first condition is an instantaneous deformation value for the bonding precursor member reaching the deformation limit and the second condition is an instantaneous deforming time value for the bonding precursor member reaching the deforming time limit. Deformation of the bonding precursor member is shut down at the deforming shut-down time value, thereby producing a deformed bond member from the bonding precursor member.
