We would need information and acceptance criteria on thermal shock testing
of blind and buried vias.
The idea is to design the vias to form chain patterns and measure their
resistance/resistance change during thermal shock.
Does anyone have experience on this or know of any standard test
pattern/method/conditions/ acceptance criteria?
Your help is highly appreciated.
Please, respond as soon as possible to IPC TechNet or directly to:
