Abstract:
A method of processing greensheets, wherein the following steps are performed: a) providing a greensheet (1) having a width, length, thickness, a first side (5) and a second side (7); b) bonding to the first side of the greensheet at least one strip (a, b, c...), wherein the strip lies in a first plane; c) bonding to the second side of the green sheet at least one strip, wherein the strip lies in a second plane; d) processing the greensheet; and e) removing the strips from the processed greensheet.
Abstract:
PROBLEM TO BE SOLVED: To provide a device for providing a uniform axial load distribution when laminating layers of a multilayer ceramic chip carrier. SOLUTION: The device comprises a base plate 1201 configured so as to support a plurality of green sheet layers from under. The base plate has at least one elastically-attached load support bar 1202 arranged adjacent to the outer edge thereof. The load support bar is attached onto one or more biasing members so that the upper surface of the load support bar can extend as far as a selected distance on the upper surface of the base plate.

Abstract:
PROBLEM TO BE SOLVED: To provide an improved method and apparatus for flattening a sintered multilayer ceramic substrate for fabricating a microelectronic chip. SOLUTION: In the apparatus for flattening the sintered-ceramic electronic package substrates having surfaces facing each other and suffering from undesirable cambers, the substrates are arranged alternately with spacers. At least one heating zone is movable to close or apart from the alternately arranged stack of the ceramic substrates and spacers and includes a heat conducting medium that performs a heating action at a desired rate by directly contacting or coming very closely to the side surface of the stack. A plunger serves for applying pressure to the stack in the direction perpendicular to the surfaces facing each other of the substrates. At least one cooling zone is movable to close or apart from the stack and includes heat the conducting medium that dissipates the heat, having been introduced by the heating zone, by directly contacting or coming very closely to the side surface of the stack. A reducing gas supply communicates with at least one heating zone and at least one cooling zone to supply the gas and maintains a controlled reducing gas atmosphere in the interior of the apparatus.
