Abstract: A laser pressure head module including: a pressure member including: a first light-transmitting member; a second light-transmitting member; and a sealed space between the first light-transmitting member and the second light-transmitting member; and a gas supply unit to supply gas to the sealed space to generate a pressing force. The second light-transmitting member is to be expanded or moved in an external direction by the pressing force.

Abstract: A mold for printing a wiring includes: a bendable part between a first lever part and a second lever part; a first protruding portion protruding from a top face of the bendable part; a second protruding portion protruding from the top face of the bendable part and at one side of the first protruding portion; and a third protruding portion protruding from the top face of the bendable part and at the other side of the first protruding portion. The first and second protruding portions are spaced apart from each other with a first hinge groove therebetween, the first and third protruding portions are spaced apart from each other with a second hinge groove therebetween, and a width of each of the first and second hinge grooves increases as they respectively extends upwardly in the thickness direction.
