Superiority of R-2400

Miniaturization of circuit boards by multilayering (cross-sectional view)

Conventional Materials   R-2400
Insufficient resin flowability makes circuit filling difficult.   Excellent resin flowability achieves superior circuit filling properties.
Multilayering of circuit boards is not possible because insulating layers cannot be formed.   Multilayering of circuit boards is possible because insulating layers can be formed satisfactorily.
