 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(qū)域形成導電層,。傳統(tǒng)化學銅方式為最穩(wěn)定,、信賴度最高的方法,。超特提供鹼性的純肥系統(tǒng),，把能密集且均勻吸附于非導電區(qū)域，形成良好催化環(huán)境,，使化學銅能完整覆蓋,。
