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”一烘箱烘烤一自来 水/超声波清洗一烘干玻璃表面水份一蚀刻工艺完成。

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 process complete.

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 the company's recommended 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%左右 5 小时内蚀刻膏无扩散。

Part of the conductive layer thickness of the thin ITO film, after printing at room temperature for about 20 minutes to complete the etching, environmental humidity control in about 5 hours within 50% hours of etching paste without diffusion.

薄膜(ITO)蚀刻温度，常温-80 C,蚀刻时间10-20分钟。

Film (ITO) etching temperature, room temperature -80 C, etching time 10-20 minutes.

玻璃(ITO)蚀刻温度，80-120 C,蚀刻时间10-20分钟。

Glass (ITO) etching temperature, 80-120 C, etching time 10-20 minutes.

烘烤后放置 2小时内无明显扩散。

No apparent diffusion was within 2 hours after baking.

用清水冲洗蚀刻完成的ITO玻璃(薄膜),必要时可采用2凉氧化钠液+超声波清洗。 ITO glass (film) with clear water to flush the etching, when necessary, can use 2% sodium hydroxide solution + ultrasonic cleaning. 烘干水分，得成品。

Drying moisture, get the finished product.

ITO 蚀刻膏注意事项： ITO etch paste precautions:

1 •生产环境温度控制在20-28 C,湿度45-60%。如在自然温度下蚀刻，环境湿度控制在 50%左右 5 小时内无扩散，湿度过高，油墨可能出现扩散现象。

1 .Production environment temperature control in 20-28 C, humidity 45-60%., such as etching in the natural temperature, environmental humidity control in about

5 hours without diffusion, humidity is too high, ink may appear diffusion phenomenon.

2．烘烤时间和温度的合理配置可以提高工作效率和节省资源，在一定范围内，蚀刻油墨 会随时间的加长和温度的升高而增强蚀刻力度和增加清洗难度。

如某ITO玻璃在100度烘

烤10分钟时蚀刻不完全时。可以采用升温到 110度 1 0分钟、或 100度 1 5分钟均能提高 蚀刻效果。

The rational allocation of 2 baking time and temperature can improve work efficiency and save resources, in a certain range, the etching ink will be increased with the increase of the extension of the time and temperature and enhanced etching efforts and increase the difficulty of cleaning.

If a ITO glass

100 degrees bake for 10 minutes in the incomplete etching. The warming up to 110 degrees for 10 minutes, or 100 degrees 15 minutes can improve the etching effect.

3．产品存放在阴凉干燥处、 6(8°保存。保质期 2(3 个月。

3 .Store in a cool and dry place, 6 (8 degree preservation. Shelf life of 2 (3 months.

4．本产品属酸性材料，在使用过程中务必避免与金属器具直接接触。如误入眼睛，立即 用大量清水冲洗，然后就近入医院做进一步处理。

4. This product is acidic material, in use process must be to avoid direct contact with the metal utensils. Such as strayed into the eyes, rinse immediately with plenty of water, and then into the nearest hospital for further treatment.

5. 本产品常温具有蚀刻能力，如不慎污染 ITO 膜或 ITO 玻璃，需立即用清水或 2%氢氧化 钠液清洗。

5 .This product has the ability to etch at room temperature, such as accidentally contaminated ITO film or ITO glass, the need to immediately wash with water or 2% sodium hydroxide solution.
