HIST-500, HIST-100 is black oxide and reduction process chemicals for multilayerPWB.
It attains good adhesion between resin and copper by minute roughening form of metal copper, and realize high reliable PWBs without haloing.
(Black Oxide & Reduction Process)

Features

• High peel strength and high heat-resistance can be obtained by roughening the metal copper minutely.
• By using this process, PWB can have high reliability without haloing occurrence.
