Abstract: The invention is directed to assembly of a plurality of joined panel parts. Some of the individual parts contain a pre-applied curable adhesive to one or more sides or edges. An initiating metal activator is applied to complementing edges and cure is activated when the parts are assembled. The pre-applied adhesive system contains monomer(s), initiators, oligomers, an acid, and a sulfonyl compound. An activating or initiating metal foil, dispersion or coating is applied to the complementary surface. The bonding is effected when the adhesive system is activated by mating the edges. The activating metal is a reducible elemental transition metal. The metal is affixed to one surface which is brought into proximity with the curable adhesive compound dispensed onto the complementing part.

Abstract: An apparatus for monitoring parts bonded by a bonder such as an RF bonder having tunable electrodes for delivering respective variable amounts of RF energy to respective portions of the bonded part includes a plurality of thermometers, at least one thermometer for each electrode, for measuring respective surface temperatures of the bonded part. The apparatus also includes an electronic digital computer that records and displays effects of tuning the electrodes and circuitry for interfacing the computer to the thermometers. The computer receives and processes temperature measurements generated by the thermometers and information on a dwell time of the bonded part in a nest with no power, the electrodes' temperatures, an ambient temperature, and a geometry of the bonded part, and the computer uses this information to determine the effects of tuning the electrodes.
