ITO蚀刻膏工艺流程
Process flow of ITO etching paste
ITO玻璃(薄膜):在其导电层需要蚀刻的部位丝网印刷“蚀刻油墨”→烘箱烘烤→自来水/超声波清洗→烘干玻璃表面水份→蚀刻工艺完成。
ITO glass (film): in the conductive layer to be etched in the site of screen printing "etching ink" - oven baking / water / ultrasonic cleaning / drying glass surface water / etching plete.
本工艺流程的特点与传统的刻蚀工艺刚好相反(传统工艺中覆盖油墨部分的导电膜被保留,而本工艺覆盖刻蚀油墨的导电膜部分则被刻蚀掉)。
The characteristics of the process flow and the traditional etching process is just the opposite (the traditional process of covering the ink part of the conductive film is retained, and this process covers the etching ink part of the conductive film is etched off).
ITO蚀刻膏具体工艺步骤:
ITO etching paste specific process steps:
将约200~400克蚀刻油墨稍稍搅拌均匀后倒至丝网印刷台面,
Will be about 400 to 200 grams of etching ink slightly stirred evenly to the screen printing table,
选用网目为(250目或420目)、水性耐酸型感光胶网板进行丝网印刷,印刷范围为需要蚀刻的部位,印刷厚度为15—20um。
Choice of mesh for (250 mesh or 420 eye), waterborne acid type photosensitive plastic mesh for screen printing, printing is the place to be etched, printing plate thickness 15 - 20um.
根据ITO玻璃(薄膜)来源及导电层厚度,选用不同的蚀刻烘烤工艺,以下为本公司建议工艺,仅供参考:
According to the ITO glass (film) source and conductive layer thickness, the use of different etching baking process, the following for pany's mended process for reference only:
部分导电层厚度较薄的ITO薄膜,印刷后常温放置约20分钟即可完成蚀刻,环境湿度控制在50
