ATC Q-BRIDGE THERMAL CONDUCTOR ATC Q-Bridge Thermal Conductor ATC’s new Q-Bridge Thermal Conductor is manufactured with the highest quality materials for reliable and repeatable performance providing a cost effective thermal management solution. These devices are constructed with Aluminum Nitride (AlN) or Beryllium Oxide (BeO) and are available in standard EIA form factors. Q-Bridge provides the designer with the ability to manage thermal conditions by directing heat to a thermal ground plane, heat sink or any other specific thermal point of interest. The inherently low capacitance makes this device virtually transparent at RF / microwave frequencies. This device has the added benefit of offering additional layers of protection to adjacent components from hot spot thermal loads. Q-Bridge provides the benefit of increased overall circuit reliability. ATC’s Q-Bridge is manufactured using one-piece construction, providing a RoHS compliant SMT package that is fully compatible with high speed automated pick-and-place processing. It is available in various EIA case sizes. Custom configurations are also available. Applications: • GaN Power Amplifiers • High RF Power Amplifiers • Filters • Synthesizers • Industrial Computers • Switch Mode Power Supplies • Pin & Laser Diodes Features: • High Thermal Conductivity Functional Applications: • Low Thermal Resistance • Between active device and adjacent ground planes • Low Capacitance • Specific contact pad to case • Increases Circuit Reliability • Contact pad to contact pad • RoHS Compliant • Direct component contact to via pad or trace • More efficient thermal management • Edges fully metalized Termination Materials ATC Termination Code Termination Materials Y Silver Platinum Non-Magnetic Termination S Silver over Magnetic Termination Note: Non-edge wrapped style in all case sizes is supplied with S termination Edge wrapped style in case sizes 0302 through 1111 is supplied with Y termination Edge wrapped style in case sizes 2010 through 3737 are supplied with S termination ATC # 001-1143 Rev.
