New magnet bar achieves high levels of coating uniformity
Bekaert introduces its adjustable magnet bar AMB v3.0 for horizontal and vertical applications at Glasstec 2008. The magnet bar enables user-friendly optimization of layer thickness uniformity and improves material utilization efficiency. Layer thickness can be tuned with a central adjusting mechanism that optimizes magnetic field strength at the target surface. Extremely robust, the AMB v3.0 provides great stability with a full application target range.
Using the AMB v3.0, target utilization will increase and the cross corner effect will be significantly reduced. Fundamental research and revolutionary design work of the mechanical constructions have lead to the magnet bar offering high repeatability.
Adaptable AC inverter’s for reliable large area glass coating
Bekaert’s new INV 400 MF AC inverter (35kHz) is part of the unique solution for sputter electronics for large area glass coating. DC power supplies next to the coating line are connected via economical DC cables (and thus leading to less EMC issues) to the new inverter which gives the flexibility to generate AC in the cathode.
The dual-cathode sputtering inverter uses a DC power supply to prevent anode contamination, particularly in reactive sputtering where dielectric materials are deposited. It also adapts to each situation so there is limited interruption of the process in a variety of sputtering methods, whilst alternation of targets between cathode and anode cleans the surface, ensuring stable deposition rates over long periods.
Self-detecting arc handles scenarios with early response and the self-seeking frequency controller are highly efficient because of low power losses. Reliable switching means low downtime and its modular structure allows easy maintenance. Special attention was given to the way of arc handling, to minimize the energy during the arc and the restoration of the plasma afterwards. The controller is designed to operate autonomously: no operator tweaking is required to get the process running. Being physically located close to the sputtering process gives unique possibilities for faster and more adequate interactions in order to better control the plasma.
New rotatable sputter targets
A further highlight at Glasstec 2008 will be Bekaert’s extended range of rotatable sputter targets with materials for the deposition of TCO layers used in PV cells (e.g. thermal sprayed AZO rotatable target, Zinc Oxide doped with Aluminum oxide (1-2 wt%)).
Koen Staelens, Product Market Manager of Bekaert Sputter Products, comments: “Because of our innovative technological vision and intensive R&D, as well as our in-depth understanding of customer applications and fast worldwide customer service, we lead in automotive and architectural rotatable sputter solutions. With the development of the INV 400 and Magnet bar AMB v3.0 we have further sharpened our competitive edge.”
And he adds: “Our dynamic philosophy and approach will drive our entry into the PV market because we have the right customized sputter hardware solutions and rotatable sputter target materials for the photovoltaic market. Since Glasstec is the world’s largest trade fair for the glass industry it is simply the number one platform for presenting our advanced technologies to a global audience.”
High performing glass separation materials
For this edition of Glasstec Bekaert Bekintex® will also participate in the Bekaert booth, presenting an extensive range of high performing glass separation materials for the production of complex glass forms, such as Novaquench, Megaquench(patented), as well as the introduction of an entirely new product in knitted fabrics.
Bekaert Bekintex® offers a great number of solutions such as knitted and woven fabrics, tape and quench products, knitted and braided sleeves, felt products and ropes. These fabrics prevent optic defects and will make the production process seamless and ever-more productive.
