Hi All,
Is there a PCB guru out there who can tell me what is the minimum recommended
pre-preg thickness for volume manufacturing? I want to increase inter-plane
capacitance by reducing the pre-preg thicnkess between my power and ground
planes. Currently we are using a pre-preg thickness of 4mils. I did some
research and found that pre-preg comes in thicknesses as low as 2mils. Can we
go as low as 2mils between planes on an FR-4 PCB designed for RoHS compliance
and still have a board which can be reliably built in high volume?
Thanks in advance for your replies.
Kindest Regards,
Gilles Aminot
