A laminating apparatus for a provisionally laminated body is provided and is configured to form an end laminated body including one of a first resin film and a second resin film conforming to protruding and recessed portions of a substrate. The laminating apparatus may include first and second laminating mechanisms. The first laminating mechanism may include a first enclosed space forming receiver, a depressurizer, a heater, and a first pressure laminator to form an intermediate laminated body from the provisionally laminated body. The second laminating mechanism may include a second enclosed space forming receiver, and a second pressure laminator to form the end laminated body from the intermediate laminated body.

Laminating apparatus

An addition/condensation curable silicone resin sheet comprising (A) an organopolysiloxane containing at least two silicon-bonded alkenyl groups and at least two silicon-bonded alkoxy or hydroxyl groups, (B) an organopolysiloxane containing at least two silicon-bonded hydrogen atoms and at least two silicon-bonded alkoxy or hydroxyl groups, (C) an organopolysiloxane containing at least two silicon atoms having two alkoxy or hydroxyl groups and one hydrogen atom on a common silicon atom, and (D) a hydrosilylation catalyst is plastic and solid or semisolid at normal temperature. The silicone resin sheet is easy to work, effective to cure, and likely to form a cured layer around an LED chip.
