Original Kurzfassung:
We present a method to design specific heater
electrode distributions on substrates with high thermal
conductivity such as sheet metal. The substrate is covered with
a thin polymer insulation layer on both sides, which are, in
turn, carrying screen printed, electrically conductive heater
electrodes and another protective polymer layer. The
temperature inside a predetermined optimization area is
demanded to be as uniform as possible, which is required for
various high-precision heating applications. A uniform
temperature distribution is required when realizing a newly
proposed ?lab on metal? approach. For this purpose, an
optimization algorithm yields the required distances between
the electrodes. The resulting electrode distribution was
numerically obtained for certain optimization areas. We show
that, for the exemplary uniform temperature distribution, the
electrode to electrode distance follows an approximately linear
decrease, starting from the centermost electrode. Finally we
describe the fabrication of a test device and show infrared
measurements of the FEM modeled uniform temperature
distribution on the experimental realized device.
