Zusammenfassung:The present invention is concerned with a method for adhesively bonding two surfaces together with a liquid adhesive and particularly is concerned with significantly reducing, if not entirely eliminating, air entrapment in the bond. In addition, the present invention is directed to an assembly for bonding two surfaces together as well as directed to the bonded surfaces obtained according to the present invention. The present invention is especially applicable for binding flat or at least substantially planar surfaces such as used for fabricating microelectronic components such as liquid crystal display assemblies and heat-sink attachments as well as various commercial applications such as windowpane glass and auto windshield applications. Two surfaces are adhesively bonded together by providing on one of the surfaces a central, single point adhesive contact deposit and providing on one of the surfaces, adhesive extending from a central point deposit in a spoke-like array diagonally across substantially the entire surface. Also provided is the article obtained by the above method as well as the assembly used for bonding the two surfaces together. The surfaces are brought together, one on top of the other, with the adhesive located between the surfaces to cause the adhesive to spread out and cover the surfaces to thereby bond them together.
