CoorsTek ADOS-90R is a thick-film ceramic electronic substrate specifically designed to block light transmittance, making it suitable for light-sensitive semiconductor devices. This substrate is formulated to absorb stray light, enhancing performance in applications where light interference is a concern. The ADOS-90R features a thickness range from 0.381 mm (0.015") to 2.54 mm (0.100") and is available in standard and custom sizes. It exhibits a flexural strength of 400 MPa (58 kpsi) and a thermal conductivity of 31 W/m-K at 20 ¬8C. The substrate also has a high volume resistivity of over 10^14 Oc-cm at 25 ¬8C, ensuring reliable electrical insulation. This product is ideal for engineers looking for durable and economical solutions in thick-film electronics, particularly in applications requiring opaque substrates.
CoorsTek developed the standards for thick-film ceramic substrates and continues to provide economical yet durable substrates for hybrid integrated circuits, surface mount devices, sensors, and other thick-film electronics.
Alumina is the material of choice for most thick-film ceramic substrates — delivering durable, cost-effective performance for hybrid electronic circuits with proven reliability. CoorsTek has engineered different grades, formulations, and thicknesses to provide an optimal fit for a variety of applications.
