PTH Treatment Process :  ( 貫孔電鍍制程 )
 
   
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.

貫孔電鍍制程主要于PCB非導電區域形成導電層。傳統化學銅方式為最穩定、信賴度最高的方法。超特提供鹼性的純肥系統，把能密集且均勻吸附于非導電區域，形成良好催化環境，使化學銅能完整覆蓋。
