Deposition mask display significant advantages

Tecan : 04 September, 2003  (New Product)
Continuing its advance into the provision of next-generation display solutions for the most demanding applications, Dorset based Tecan is experiencing increases, both in interest, and orders, for electroformed vacuum deposition masks, making it a front runner in the race for advanced display technologies.
Typically used to deposit inks onto substrates during the manufacture of an increasingly expansive range of flat panel display technologies, the high-accuracy masks offer a number of advantages over traditional techniques such as inkjet printing or screen printing with emulsion stencils. The electroforming process employed by the company at its world-class facility is exceptionally well-refined, producing high-tolerance display masks with burr-free aperture edges and controllable draft angles to ensure optimum print definition. Display technologies able to take advantage of the masks include liquid crystal displays, organic and inorganic light-emitting diode displays, plasma panel displays, vacuum fluorescent displays and field emission displays.

Manufactured using highly accurate electroforming techniques, the masks benefit from low tooling costs with superior tolerances, delivering greater density designs with higher accuracy aperture edges. Multi-level masks can also be produced, with 'stepped' recesses, limiting the need for spacer sheets in multiple-sheet sets, if required. Single masks, traditional multi-mask sets, stepped masks and frame systems are all available to meet the individual needs of the customer.

During manufacture, masks are subjected to computerised co-ordinate measuring as part of the company's rigorous statistical process control system to produce fully traceable 'proven' batches, suitable for delivery direct to the customer's production environment. All specified variables, such as aperture size, tolerance and thickness, are accurately measured and logged ensuring users can by-pass their own detailed goods-in inspection, if required. As a result, time and costs are saved, and traceable quality control with hard copy back-up documents are assured.

In recent years, and over the last twelve months in particular, the company has increased pace on a series of pro-active initiatives, helping it to become more involved with various forums and projects under the LINK Information Storage and Displays Programme. During this period a growing number of leading-edge display designers and providers, along with those in parallel markets, have become involved with the company in joint-development ventures.

Furthering this initiative, Tecan is planning to host a seminar and workshop in the central Cambridge area, in November 2003, to demonstrate its full range of capabilities to the burgeoning display technology community in the region, many of which are operating at the evolutionary edge of next-generation flat panel display technology.
