Abstract: A component for use in manufacturing articles such as printed circuit boards having a sheet of copper foil and a metal sheet. One surface of each of the copper sheet and the metal sheet are essentially uncontaminated and engageable with each other at an interface. The copper sheet and the metal sheet are maintained together to define an unjoined and substantially uncontaminated central zone inwardly of the edges of the sheets. A bond is formed between the copper sheet and the metallic sheet along the peripheral edges thereof. The bond has sufficient adhesive strength to maintain the sheets together during manual handling of the component at room temperatures. The bond is temperature-sensitive, wherein the bond deteriorates when exposed to temperatures in excess of about 180° F. (about 82° C.).

Abstract: An applicator syringe for containing and dispensing moisture-sensitive or moisture-reactive adhesives comprises a generally sealed barrel containing a plunger having a non-stick polymeric seal and a hydrocarbon grease disposed between the seal and the adhesive contained in the barrel. As the plunger advances in the barrel, a sealing, thin film of the hydrocarbon grease is deposited on the interior walls of the syringe barrel to provide a moisture-impervious seal between the polymeric seal and barrel and to aid in smooth advancement of the plunger in the barrel.
