-delamination of FPCs observed when cleaning with safewash; (LTU suggested to clean wit acetone)

-the wirebond tests presented in the slides have tails of 250um;

-according to theory the diffuser supporting the FPC dissipates ultrasonic energy; supporting the FPC directly on a solid substrate reduces dissipation of ultrasonic energy and improves wirebonding quality; [This is not obvious from this results]
