3、力, 不殘膠 - 弱黏, 好撕除- 撕離不帶電應用二: ito glass protection (sg: sensing glass)博霖型號: af915- ito 玻璃貼合 oca 前的保護- ito 接觸角變化不可超過15度, 無離型轉移confidential為什麼要選用bojal抗靜電護膜?1. 好操作: bojal anti-static 護膜撕除離型膜時依然保持平坦. 好操作 = 產能提升 & 良率提升非抗靜電護膜, 撕除離型膜時會因靜電導致護膜捲曲.2. 降低灰塵吸附: 撕除離型膜時, 若無抗靜電, 容易吸引附近大量灰塵到膠面上, 降低產品潔淨度. 博霖 抗靜電膠可有

4、效解決此困擾.3. 撕離不帶電: 液晶, ic原件, 電路板etc.撕除bojal抗靜電保護膜時, 其特殊抗靜電膠可避免撕除靜電破壞被貼物下面的液晶, ic, 電路板等對靜電敏感之物件.4. 表面無白色釋出物:它牌護膜表面會有白色釋出物. 可擦拭 = 污染源. bojal 護膜沒有此問題.博霖 gasket材料應用abab電容式觸控面板黏著區: 觸控面板黏合lcm兩種辦法: 1.用光學膠2.用 gasket + 2片ar cover glassito glass (sensing glass)oca 光學膠 (175um)lcmcover glassito glass (sensing gla
