We have used it for single sided boards and we found the Z expansion to be 
excessive. I would suspect plating vias would not be very reliable once 
thermal expansion started. I recommend speaking with your board vendors as 
they should have reliable data to go by.		-Ed Current

Subject: 	CEM1 Substrate material

Has anyone used CEM1 substrate material?  Can CEM1
be plated through?

I believe it is a low cost material that is used
in the mass production of comsumer products.
Holes are punched rather than drilled.

Thank you in advance for your help.
