Novel Scan Concept Extends Image Field
At the Laser World of Photonics tradeshow in Munich, Germany, SCANLAB GmbH and ACS Motion Control Ltd. are premiering a new powerful scan concept. The jointly developed syncAXIS control software enables simultaneous control of a 2D scan head and a 2D mechanical stage with two servo motors. The combined system substantially increases the image field size for wide-area marking, and in addition provides superior capabilities for cutting of glass, drilling of large PCBs and laser micro-machining. Unlike tiled processing, this innovative laser processing system with an extended image field can significantly slash process times, thereby delivering enhanced productivity and cost reduction in manufacturing.
Until now, a scanner's image field has been the key limitation in laser processing – regardless of whether that entails marking, cutting, drilling or even microstructuring. Wide-area process tasks are executed stepby-step, by processing individual 'tiles'. This approach can involve relatively long process times and stitching errors, i.e. marking displacements at image field boundaries.
To eradicate those deficiencies, the two companies developed the syncAXIS control software, that enables to simultaneously control a laser scanner and a mechanical stage to substantially extend the image field, increase processing throughput while achieving unprecedented levels of accuracy. Here, a demonstration system that consists of: A SCANLAB excelliSCAN 14 scan head with a telecentric 100-mm objective for a 54 x 54 mm2 image field that is controlled by an RTC6 scanner controller; an ACS Motion Control NPMpm NanoPWM dual axis drive module controlling a high accuracy XY stage, and a picosecond laser. The control concept is based on slaving the mechanical stage to the scan system and thus extending the actual field of view of the scanner. Operating the entire system is similar to operating a system that consists only of a scan head and its associated RTC6 controller, utilizing similar set of commands. Therefore, any application that currently can operate a SCANLAB scan head will be able to operate such a combined system with minimal effort.
Boosted productivity thanks to simultaneous motions
Compared to conventional tiled laser processing, significant process advantages can be accrued by intelligently coupling and simultaneously controlling the scan system and an XY stage. In addition to avoidance of stitching errors, accuracy is substantially improved and throughput is increased by up to 40%.
"Numerous test runs by our application experts impressively demonstrate practicality of the new scan concept. In every case, significant process advantages were confirmed when compared to tiling – whether for marking large circular shapes with text, circular shapes in a matrix, diamond patterns or multiple bore holes," reports SCANLAB CTO Norbert Petschik on the successful collaboration. "Even special test patterns for checking the impact of vibrations due to the XY stage's high dynamics revealed no residual effects".

Un nuovo concetto di scansione amplia il campo visivo
L'innovativo software di controllo offre molti vantaggi nel processo della lavorazione laser
Alla fiera Laser World of Photonics di Monaco SCANLAB GmbH e ACS Motion Control Inc. presentano un nuovo concetto di scansione. Il software di controllo syncAXIS control, frutto della collaborazione tra le due aziende, consente la gestione simultanea di una testa di scansione 2D e di una piastra di posizionamento XY meccanica con doppio servo assi. Il sistema combinato espande considerevolmente il campo visivo, consentendo quindi la marcatura di superfici estese, e si rivela estremamente utile per il taglio del vetro e la foratura di circuiti stampati di grandi dimensioni nell'ambito della produzione di componenti elettronici e della microlavorazione. Diversamente dalla lavorazione a piccoli segmenti, la lavorazione laser simultanea con campo visivo più ampio riduce in modo significativo i tempi e i costi aumentando così la produttività.
