High-performance evaporation masks, for use across a wide range of selective
vacuum chamber processes, have been further enhanced, by leading provider
Tecan - combining coplanar rigidity with optimum aperture accuracy.

Using Photo ElectroForming (PEF) and photo-etching techniques, the company
produces cost-effective nickel and stainless steel masks which out-perform
traditional alternatives. The technique combines 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. Similarly,
multi-level masks can be produced with the thinnest possible cross-section
where apertures occur, to virtually eliminate photo-shadow and optimise
process accuracy. The technology also allows selective areas across the
mask to remain thicker - assuring coplanarity and operational robustness.

An established ability to fabricate all mask types ensures traditional and
new market requirements are catered for from a single source. The company
can produce whatever is required, from traditional multi-mask sets, to
stepped masks in stainless steel or nickel. The manufacturing techniques
cost-effectively cater for development, prototyping, small-, medium- and
large-scale production applications - affording consistently accurate
results and low-maintenance parts. Frames for any process need can also be
supplied.

The PEF 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.

Typical applications include a wide number of simple and complex
micro-engineered electronic components and products, in industrial,
aerospace, automotive, medical and pharmaceutical markets. For example,
evaporation-depositing gold or silver contacts onto quartz crystal
oscillator tracks. They are also used in sputtering and spray processes for
the fabrication of similar components onto substrates such as silicon or
glass and for the deposition of a wide range of other surface finishes.
Display technologies also benefit from employing the masks - such as liquid
crystal displays, organic and inorganic light-emitting diode displays,
plasma panel displays, vacuum fluorescent displays and field emission
displays.
