Double Sided (Silver / Copper) Polymer Through Hole Board
Features
Significant cost reduction is possible by replacing copper plating through-hole PWB with polymer through-hole PWB.
High density circuit design is widely available.
Double sided surface mount PWB is available by using polymer through-hole PWB.
Highly reliable PWB is realized by using polymer through-holes on paper phenolic board.
