Quartz press bars are a critical component widely used in the manufacturing and repair of electronic devices, particularly in hot press equipment and within the LCD industry.
Quartz press bars can be custom-manufactured to meet specific customer requirements, including various shapes (such as L-shaped, T-shaped, square bars, double-stepped, etc.), dimensions, and precision levels. Professional manufacturers possess advanced processing equipment and extensive manufacturing experience, enabling them to provide customers with high-quality, high-precision quartz press bar products.

High Light Transmittance
Quartz press bars exhibit extremely high light transmittance, typically reaching 99% or greater, ensuring efficient light transmission during pressing processes.
Excellent Flatness
Their surface flatness is exceptionally high, often achieving ±0.002mm, which facilitates high-precision pressing operations.
High-Temperature and Chemical Resistance
The quartz material demonstrates outstanding resistance to high temperatures and chemical substances, maintaining stability even in harsh working environments.
High Hardness
Quartz has a high hardness, providing the press bars with good wear resistance and scratch resistance during use.
アプリケーション・シナリオ
Quartz press bars are widely applicable in various hot press equipment, such as COG Bonders, OLB Bonders, FPC Bonders, PCB Bonders, and pressing equipment used for repair purposes.
In the LCD industry, they are also extensively used in screen repair and production processes to improve product manufacturing efficiency and yield rates.
Handle with Care
Quartz glass products are valuable materials and must be handled with care to avoid collisions and drops.
Temperature Limits
All types of quartz glass have a maximum operating temperature. This temperature should not be exceeded, as it may result in devitrification or softening and deformation.
Cleaning Procedures
Quartz glass products intended for high-temperature use must be thoroughly cleaned before use. This can be accomplished by soaking in a suitable cleaning solution, followed by rinsing with high-purity water or treatment with alcohol.
Avoid Thermal Shock
Although quartz glass has good thermal stability, variations in residual stress and product shape can result in varying levels of thermal shock resistance. These differences should be taken into consideration during use.
Prevent Contact with Alkaline Substances
As an acidic material, quartz glass should be kept away from alkaline substances (such as water glass, asbestos, and compounds of potassium and sodium), particularly at high temperatures, as contact will significantly reduce its crystallization resistance.
よくある質問
石英ガラスは硬くて脆い材料で、物理的、化学的性質が優れ、機械的硬度が非常に高く、電気絶縁性がよく、高温と耐食性に優れ、遅延性能が低く安定で、光透過性がよい。半導体、光学、電気、化学、航空宇宙、自動車などの分野で広く使用されている。硬くて脆い材料は加工が難しく、多くの分野で刃先の倒れが小さく、材料ロスが少なく、断面粗さが小さく、切断厚さ範囲が広い切断加工が急務となっている。石英ガラスの伝統的な切断方法は機械的切断、すなわち砥石切断である。非伝統的な切断方法には、ウォータージェット切断、電気化学放電ワイヤー切断、連続レーザー切断などがある。機械的切断はコストが低いが、ホイールと材料が接触するため工具の摩耗が大きく、材料が工具によって汚染されやすい。石英ガラスはエッジ崩壊、マイクロクラック、残留応力が発生しやすく、材料の強度や性能に影響する！曲線切断が難しく、研削や研磨などの後処理が必要。レーザー切断は材料に直接触れないため、接触応力がなく、複雑な曲線切断が可能です。ピコ秒レーザーは、スポット径が小さい、精度が高い、材料との作用時間が短い、作用面積が小さいなどの利点があり、硬くて脆い材料の加工に適しています。
