Hello,
I am very disappointed by this announcement because I spent quite some effort to design RF electronics for this stack up.
Discontinuing the stack up after just two years is a no go for me. Two years is a typical development duration for more advanced projects. This happened overnight without any preannouncement (At least I did not notice it).
I am (and also others I know personally are) in the middle of a development. The stackup was verified to support analog RF signals up to 20GHz. We must now find another prototyping PCB house.
My confidence in AISLER is shattered.
Regards,
Tobias
