PTH Treatment Process :  ( 貫孔电镀制程 )
 
   
A PTH process has the function, to build up a conductive layer on the nonconductive areas. The classical PTH process based on electroless copper is most widely in operation and provides a high reliability. Jetchem's alkaline activator system, provides a very dense and uniform Palladium layer, with an excellent initial coverage power to the electroless copper.

贯孔电镀制程主要于PCB非导电区域形成导电层。传统化学銅方式为最稳定、信赖度最高的方法。超特提供鹼性的纯肥系统，把能密集且均勻吸附于非导电区域，形成良好催化环境，使化學铜能完整覆蓋。
