Hi,
Some days ago I was told,that target pads in YAG laser drilled microvias are
suffering of "like pink-ring" phenomena after permanganate desmear if the
target layer is treated by "oxide substitution" based on peroxide ( such as
Multibond,Cobra bond,Circubond,Alphaprep etc).
What are comments on such statement??
Happy X-mass
