Wireless telemetry electronic circuit board for high temperature environments

In a combustion turbine engine, a circuit assembly affixed to a turbine blade in the engine for receiving sensed information about the condition of said turbine blade and transmitting said sensed information to a receiver external to said turbine engine, said circuit assembly comprising:

• a printed circuit board comprising an alumina substrate and having conductive traces formed of a thick film gold paste deposited thereon;
• discrete active and passive components of said circuit assembly being attached to said printed circuit board by gold powder diffused under high temperature;
• and,
• gold wire bonding between said conductive traces and said active components in order to complete said circuit assembly, said gold wire bonding being oriented parallel to a longitudinal axis of the turbine blade which is a direction of centrifugal forces to be exerted upon said printed circuit board during operation of the turbine engine.
