Abstract: Printed circuit boards comprise laminates, e.g. CEM-3 laminates, having insulating substrates which include polymeric particles, particularly core-shell particles having an average diameter of about 0.05 to 30 mu m, which reduce the dielectric constant and dissipation factor of such laminates. Comparative Tracking Index (CTI) is significantly improved.
