卷对卷丝网印刷机在超薄挠性覆铜箔层压板上丝网印刷液态光致抗蚀液,实现COF精细线路的制作。研究了液态光致抗蚀液的感光性能与分辨率力等性能,考察了制作出COF的线路效果。实验结果表明,液态光致抗蚀液网印的针孔数随厚度的减小而增加,液态光致抗蚀剂曝光级数随曝光能量的变化趋势与干膜是一致的,11μm厚液态光致抗蚀剂分辨的最小线路宽达到25μm,满足COF精细线路制作的要求。
捲對捲絲網印刷機在超薄撓性覆銅箔層壓闆上絲網印刷液態光緻抗蝕液,實現COF精細線路的製作。研究瞭液態光緻抗蝕液的感光性能與分辨率力等性能,攷察瞭製作齣COF的線路效果。實驗結果錶明,液態光緻抗蝕液網印的針孔數隨厚度的減小而增加,液態光緻抗蝕劑曝光級數隨曝光能量的變化趨勢與榦膜是一緻的,11μm厚液態光緻抗蝕劑分辨的最小線路寬達到25μm,滿足COF精細線路製作的要求。

Liquid photoresist was printed on ultra thin and flexible copper-clad laminates by Roll to Roll silk-screen printing machine.Photosensitive property and resolution of liquid photoresist were studied and effects of COF fine lines were investigated.The results indicate pin holes may increase with diminishing thickness of liquid photoresist,the relationship of exposing level and light Intensity of liquid photoresist is corresponded with that of dry film and the maximal resolution of fine lines is caught up to 25 μm with liquid photoresist in thickness of 11 μm.Liquid photoresist shows good agreement with manufacturing COF with fine lines.
