CEM-3 copper clad laminates (CCL) were made from epoxy bromide A80
curing agents of phenolic novolac (PN)
bisphenol F novolac (BPFN) and bisphenol A novolac (BPAN) with accelerants of DMP-30
HMTA and 2-MZ. The effects of these three novolacs on the properties of CEM-3CCL
such as mechanical properties
electrical properties
water absorbance and heat resistance
were discussed. The results show that the mechanical properties of CEM-3CCL fabricated by the three novolacs don’t have distinguished difference. The water absorbance
