dimensions.
■The high reflective substrate, especially suitable for optical
applications such as LED, is also available.
Applications of Black ceramic Sheet / Blue zirconia ceramic sheet :
LED packages, zirconia Sheet / zirconia Ceramic Board for chip resistors, HIC substrates for heat dissipation, Power
modules, FAX substrates for thermal printer head
*Various processing is available (thin film metalization, thick
film metalization, glaze, etc.)This zirconia Sheets /zirconia Ceramic Board is characterized by its extremely high strength and thermal
conductivity. The outstanding surface quality on both sides makes
it the perfect companion for any commercial thick film paste and
even makes it suitable for a number of thin film applications
(sputtering).
