感光剂

A photosensitive resin for UV curing acrylic powder coating has been synthesized by esterification of methacrylic acid and GMA-type acrylic resin at the presence of ethyl acetate as solvent, tetramethylammonium chloride as catalyst, YK as inhibitor.

以醋酸丁酯为溶剂，四甲基氯化铵为催化剂，氮氧自由基为阻聚剂，由甲基丙烯酸缩水甘油酯类丙烯酸树脂与甲基丙烯酸酯化反应制得了UV固化粉末涂料用感光性丙烯酸树脂。

There are TAIHONG 2LPSE0503MW-250 single unadhesive ED flexible copper coated lamination and Nippon Steel CIPW-25080 single ED FCCL.Regards to photoresists, Dupont FX915 dry film would be the best choice for the production of COF FPC after the comparison in photosensitive property, resolution, adhesiveness and operating procedure between the different resist thicknesses of Dupont FX900 series.

光致抗蚀剂方面：通过对比杜邦FX900系列两种不同抗蚀层厚度干膜(FX930与FX915)的感光性能、分辨率、附着力、操作工艺等，确定出杜邦FX915(抗蚀层厚度15μm)为更适用于COF挠性印制板制作的干膜；并对干膜的曝光参数进行了优化，最佳曝光级数5级(相对于21级曝光尺)，曝光能量片式150mJ/cm~2、卷式110mJ/cm~2，使其更加适合于精细线路的制作。

Even partial tenting using a liquid photoimageable solder mask will cause contact problems, as the mask liquid will tend to run away through the via hole.

即使是用液态感光防焊剂局部覆盖也会导致接触问题，因为液态覆盖物会通过过孔流动。
