about acoustic impedance layer

Hello everybody,

Now we're developing a high frequency ultrasound probe, however we have difficulties in adhering between the first matching layer and ceramic. Whether do you some advice or service about it? Thanks a lot ! Please email to me: liyongchuan@asisz.com

Re: about acoustic impedance layer
Hello Peter,
What are you calling high frequency? Most companies use 25 MHz or 30 MHz as a cut off where anything under these frequencies will follow standard transducer production. Above these frequencies, the active element is so thin that it is often bonded onto a solid, flat substrate (often a fused quartz or silica) to give the xtal the support needed.

Best Regards
E
