Tretrafunctional epoxy has three carbon bonding sites and is extremely
brittle. Therefore, drilling, routing and processing in general is
difficult. Multifunctional is a combination of tretrafunctional and
difunctional (two carbon bonds) which is less brittle and more process
friendly. Both will have about the same Tg.

Subject: [TN] laminate types?


Hello Technet
I've got a question for our PWB experts today.  What is the difference
between tetrafunctional and multifunctional laminate?
