       To microelectronics companies, we adopt DPC technology to process ceramic circuits, meeting their demands for mass production of the ceramic circuits. To scientific research institutions, we provide the required chemicals for ceramic circuits processing. To researchers, we provide the services of magnetron sputtering, film and electroplating processing.

        The following is a brief introduction to 3535 standard edition, with sample pictures:

        Alumina purity is 96%, material plate thickness is 0.5mm, copper plating thickness is 65±15μm.

        The color of solder-resist ink is optional, you can choose double-sided white or green. Immersion silver thickness is 0.2-0.4μm.
