Phoenix, Arizona USA, March 9, 2004 - Continuing breakthroughs established the TLC Phoenix-600® High-Accuracy industry choice for microsheet glass singulation.
With the microelectronics industry constantly moving towards smaller, thinner and lighter glass substrates for displays, photonics, optics, sensors and a host of other products, it has long presented a problem for the glass cutting industry, which generally had limitations of cutting 0.012"/0.30 mm thick substrates. Thinner substrates produced very poor yields and high production costs.
For the past two years, TLC has been working in close conjunction with the aerospace industry to develop a singulation process with the TLC Phoenix-600® on even thinner glass. The most recent progress has been to establish successful parameters to produce a repeatable process for cutting 0.006"/0.15 mm microsheet substrates with high yields - still using a carbide wheel. Pressed even further by weight limitations, the aerospace industry has asked TLC to continue research in cutting 0.003"/0.075 mm microsheet glass using a diamond stylus.
As the TLC Phoenix-600® will cut circular and curvilinear, as well as rectilinear (X-Y) parts, its multifunctionality is easily incorporated into production lines for a wide variety of specialty micro-sized thin, flat glass parts.
One customer requested TLC to develop a process to cut 0.027"/0.70 mm glass into 0.040"/1.0 mm X 0.040"/1.0 mm squares, while maintaining part polarity after singulation. This being accomplished, the customer is currently looking forward to doubling their production capacity within the next few months.
More recently, TLC was asked to develop a process to cut 0.35"/9.0 mm circles out of 0.043"/1.1 mm Borofloat with a tolerance of +0.00 mm to -0.2 mm. Evaluation analysis of test results and is quite favorable and afterbreak edge tolerance meets qualification specifications.
To reduce contamination, TLC has perfected formulas to cut through protective polymer membranes (Nitto® tape or similar coating) and the glass at the same time, leaving the protective layer on the glass until it is placed into its final application.
With the introduction of the Gen-3 TLC Phoenix-600®, TLC anticipates meeting the ever-increasing difficult challenges of the thin, flat specialty glass cutting industries.
