年月 修正補充 A7 B7 五、發明說明(/ ) 本發明關於一種具有貫穿接觸部(貫穿接點)( Durchkotaktieerung)的電路板的製造方法。 I I I i —---- — I (請先閱讀背面之沈意事項再填寫本頁) 貫穿接觸的銅層狀物(Laminat )在做構造化( Strukturierung )時的一個問題爲··要保護該孔免受刻飽介 質侵蝕。 在M-Hammel的「導入電路板技術」卯〜100頁,Eugen G. Lenze出版公司(1991)中,爲解決此問題,提議用搭 營技術(Tenting Technik)。在此所用之刻融抵抗物爲一種 固體膜(乾膜抵抗物),它一如一天幕(Zelt)位在孔的 範圍上》但這種方法的缺點爲在貫穿接點周圍形成銅環, 如此電路板的接線密度就會受限。 依 H. Schwab「Electrodeposition of Photoresists fo Printed Wiring Board Application」EIPC 冬令會議 1992,如 果使用施有電浸(電沈積)(electrodeposition)漆的正光 抵抗物做刻蝕抵抗物,則這種環可減小或甚至完全消除。 但一般工程中使用之正光抵抗物却需較長的曝光時間。此 外,電浸漆的技術成本很高。 經濟部智慧財產局員工消費合作社印製 本發明的目的在於提供一種較低成本的方法,將貫穿 接觸的內層及外層作構造化。 茲發現,當使用一種負性工作的液體電鍍抵抗物,可 使銅環形成的情事大大減少或完全避免。 本發明的標的爲一種具有貫穿接點的電路板的製造方 法,‘其特徵在以下的方法步驟: A)將一貫穿接觸之銅層狀物兩側施覆—種負電鍍抵抗 3 本紙張尺度適用中國國家揉準(CNS)A4規格(210 X 297公轚)
