CoreFlow’s innovative aeromechanical non-contact solutions significantly improved yield and production performance at a world-renown FPD manufacturer.
The Challenge
When we first met with our customer, an Asia-based FPD manufacturer, they were operating non-CoreFlow air-floating platforms for conveying and inspecting glass substrates. They were experiencing instability of the floating glass, leading to the following difficulties:
- Frequent scratching of the glass substrate, due to contact with the conveyor.
- Poor production yield as a result of the high reject rate.
- Inefficient pressure supply, leading to high energy costs.
Following a series of meetings, the customer agreed to test CoreFlow’s high-precision air-floating solution for handling glass substrates of a variety of sizes and thicknesses and was highly satisfied with the results.
The Solution
In 2018, the customer kicked-off a 3-year program to upgrade their existing conveyor lines with CoreFlow’s solution. The improved stability enabled the customer to use the conveyor for glass substrates of a variety of sizes and thicknesses.
To simplify the upgrade, Coreflow designed special PA and PV air bars in accordance with existing form factors, allowing for a seamless retrofit that required no support frame modifications. “The exceptional added value of our non-contact system is that it can be utilized to support glass substrates of multiple dimensions and thicknesses using the same conveyor”, explained Ami Herman, CoreFlow’s VP of Sales and Marketing. “This outstanding capability is achieved thanks to CoreFlow’s solution-oriented approach, based on the SmartNozzle™ technology, which is at the heart of CoreFlow's non-contact air floating systems.”
Results
The customer has reported the following achievements since implementing the CoreFlow solution:
- Zero scratches!
- Improved production yield due to elimination of substrate damage.
- Decrease of 80% in operating costs, thanks to the reduced air pressure requirements.
The customer plans to continue to upgrade additional lines with CoreFlow solutions, and in parallel, intends to build new lines using CoreFlow systems as well.
“This successful joint process illustrates the value we place on the establishment of close cooperation with our partners,” said Mr. Herman. “It all starts with studying the requirements and understanding the existing challenges in order to design and deliver advanced, customized substrate-handling solutions. Working closely with our partners, understanding their current and future needs, and designing the solutions to address them is a key to a successful long-term relationship”.

CoreFlow Announces New Stage Blockage Monitoring System for PV (Pressure Vacuum) air-floating stages
CoreFlow Ltd., a leading solutions provider of non-contact advanced handling and conveying systems announced the successful testing of the newly developed monitoring system for Air Floating stages.
Stage blockage events reduce manufacturing system performance, harming substrate floating height precision. In extreme cases, blockages may cause direct contact between the substrate and the stage surface, damaging the substrate.
The system, monitors the stage supply in the process area, enabling alerts in a short time after a blockage occurs. This indication allows the production team to pinpoint an occurring event faster after one glass cycle time, significantly reducing troubleshooting time and increasing production yield.
The Stage Blockage monitoring system is compatible with CoreFlow PV Air Floating or Vacuum stages. For example, it can be used on coating systems, inspection systems, inkjet printers, and it is scalable to any substrate size with any nozzles pattern distribution like orthogonal in two axes, staggered distribution in one axis, axis-symmetric, or random distribution. The system can set to monitor all vacuum nozzles in the system or only part of them.
"The Stage Blockage Monitoring System that was develop by CoreFlow’s leading engineering team, brings our customers a competitive edge and a great value in their product yield and quality," said Eric Joely, CoreFlow CEO. "We are proud to continue and develop leading-edge products for our customer to support the growing challenges and demands in the FPD industry"

CoreFlow HQ, August 26, 2020 – CoreFlow Ltd., a leading solution provider of non-contact advanced handling and conveying systems, announced the successful testing of CobraMotion™ - a newly-developed technology designed to prevent damage to the edges of glass substrates in flat-panel display (FPD) fabrication.
As glass substrates become larger and thinner, new and innovative non-contact handling and conveying techniques are needed to protect them from damage. The primary challenge is to ensure that the leading and trailing edges of the substrate, which naturally tend to bend toward the handling platform, will not contact the platform – thus avoiding scratches and breakage.
CobraMotion™ is a unique pressure/vacuum (PV) technology designed to avoid contact between a PV stage and the warped glass substrate. With CobraMotion™, the vacuum force and mass flow rate (MFR) applied to the leading edge and the trailing edge of the glass are reduced, while the vacuum force and MFR applied to the center of the glass remain constant. As a result, the equilibrium height of the glass is higher at the edges than in the center, thus preventing damage to the edges of the substrate, and improving yields.
“CobraMotion™ is a unique solution that was developed by CoreFlow to give our customers a competitive edge and outstanding product yield and quality," said Eric Joely, CoreFlow’s CEO. "We are proud to develop leading-edge technologies and solutions, and to help our customers meet the growing demands and challenges in the FPD industry"
