【摘要】：介紹了一種基于超聲噴涂的電路印刷方法,適用于各種柔性材質(zhì)的基體,可以更高效、更環(huán)保地完成柔性印刷電路(FPC)的制造。其主要思想是:納米銀導(dǎo)電油墨通過超聲噴頭霧化,進(jìn)而噴涂在覆蓋有金屬掩膜版的聚酰亞胺(PI)膜基體上,低溫?zé)Y(jié)(125℃×20 min)之后就得到柔性電路。測試結(jié)果表明,圖案化的導(dǎo)電線路(寬度為500mm)經(jīng)過多次彎曲后仍能保持良好的導(dǎo)電性,其表面方阻隨噴涂層數(shù)的增多而穩(wěn)定地減小,8層涂覆所得線路的方阻為(21±2)mΩ/sq。掃描電鏡觀察表明,導(dǎo)電線路平整光滑,毛邊誤差在50mm以內(nèi)。
[Abstract]:This paper introduces a circuit printing method based on ultrasonic spraying, which is suitable for various flexible materials. It can make flexible printing circuit (FPC) more efficient and environmentally friendly. The main idea is that nano-silver conductive ink is sprayed on the substrate of polyimide (Pi) film covered with metal mask by ultrasonic spray head, and the flexible circuit is obtained after sintering at low temperature (125 鈩，
