目前觸碰面板針對玻璃基板對成本要求價格低廉且厚度更薄,而現階段最大問題在於Sensor製程後玻璃的強度不足,導致摔落時易碎。面對此問題,業界已研發出物理和化學方式的強度加工方式,對玻璃的強度問題可得到很大改善玻璃二次強化,化學二次強化主要利用HF微蝕刻玻璃斷面因切割所產生之延伸性裂痕,使裂痕縮小甚至消失來提升產品機械抗壓力。
本次實驗則是針對化學二次強化方式,利用逆向工程法從蝕刻條件?研磨條件?切割裂片條件回推前製程進行探討影響二次強化之各相關因素。
在製程中 HF濃度會因為蝕刻玻璃而逐漸下降,進而影響蝕刻速率,但本身若蝕刻過久,會造成產品外觀不良,而蝕刻不足則裂痕無法消除或減輕,無法達到機械抗壓力增加的目的,若玻璃切割與磨邊製程不佳,會產生許多 >100 μm以上的延伸性裂痕 (crack),會因為需使用較長時間之蝕刻時間,則會產生明顯的玻璃邊緣水波紋,造成外觀不良,若選擇高密度的磨輪去進行磨邊,降低延伸性裂痕的程度,雖有助於化學二強的修補效果,但製程耗時且成本高,亦不具量產性。故本研究將針對二次強化之蝕刻管控、研磨、切割各條件進行測試,以4PBT(4-Point Bending Test)分析其各條件抗壓力之平均值及B10壽命,找出最佳強化條件,提升目前現有之基板抗壓應力性質。


This experiment is for the secondary hardening chemical methods, the use of reverse engineering method from the etching→Grinding→Cutting pushed back the process to discuss the impact of all relevant factors secondary hardening.
Process in the HF concentration because of etched glass and gradually decline, thereby affecting the etch rate, but itself if etching too long, will result in poor product appearance, and lack of etching the cracks can’t be eliminated or reduced, can not achieve the mechanical resistance to pressure increase purposes, If the glass cutting and grinding processes poorly, will produce a lot of> 100 um or more of crack extension (crack), because of the need to use the longer etching time, could have a substantial edge glass water ripples, resulting in poor appearance, If you choose to carry out high-density grinding wheel, reduce the degree of extension of cracks, may help repair two strong chemical effect, but the process is time consuming and costly, nor a mass productivity.
Therefore, this study will be tested against the strengthening of the
Management and control of secondary etching, grinding, cutting various conditions to 4PBT(4-Point Bending Test) analyze their respective conditions of AVG(Average) anti-stress and B10, to find the best conditions for strengthening.
