Heat Spreaders
Characterized for Laser Diode and RF/Microwave Monolithic Integrated Circuits
The ALU and BeO family of devices provide an optimized mounting platform for Gallium Arsenide (GaAs) devices providing Dielectric Standoff, Thermal Spreading, and CTE Matching while the AlN series is optimized for Silicon (Si) devices.
Tabulated thermal resistance values assure device Junction Temperature control and management with the entire product family of ALU---, BeO---, ALN--- submount devices
Characteristics
5 micron dielectric border on the front side has “zero burrs” to facilitate edge mounted laser diodes and arrays and prevent solder/epoxy squeeze out. The back side is fully metalized.
Edge to edge surface planarity on both sides is guaranteed at < 3 microns
Series Resonance: (C < 1pf) > 30GHZ
(C = 1to 2pf) > 22 GHZ
Breakdown Voltage: > 100V
Ordering Information
| Material | ALU : Alumina (99.6%) BeO: Berylium Oxide AIN: Aluminum Nitride |
 |
| Thicknesses Available |
0.005”, 0.010”, 0.015”, 0.020”, and 0.025” |

See detailed product selection table (below) for specific sizes and material properties to meet your application.
In the event that one of our standard products does not meet your needs, Ion Beam Milling can fabricate a custom product to your specifications
Application Note
VCSEL (bottom surface) temperature = Tj = Ta + Pd (total thermal resistance)
| Example 1 | Tj = 25 °C + 5W (0.108 + 4.52 +0.108) = 48.7 °C |
| Example 2 | Tj = 25 °C + 5W (0.108 + 0.49 +0.108) = 28.53 °C |
