02:44 Jul-08-2002 Re: Bonding transducer using Indium : Hi,All, : Could anyone describe the procedures to bond a LiNbO3 transducer onto a buffer rod? What are the advantages/disadvantages comparing to epoxy resin bond? Thanks for the help.
My laboratory used to realise transducers like this but the activity is now deleted. First advantage is to be able to realise transducers of above 30MHz. The limit is then your ability to make the transducer thin (My labo made 2GHz transducer i think...). In vacuum, Indium or gold can be used to join the transducer and the buffer rod. Can't explain the details though...
I'm personnaly looking for industries that can realise 30MHz transducers "on demand" with specific transducer dimensions, sapphir buffer rod, etc... Any idea ? Panametrics don't !

An article in “Composites World Magazine” showcases Non
Destructive Testing of aero-structures
with Laser Shearography.
Over the years Dantec Dynamics has supplied many solutions for the
aerospace industry. Referring to specific customer projects
several of these cases are examined to outline the advantages of
using Laser Shearography for automated defect detection.
