Evaporation masks minimise process costs
Tecan has developed high-performance evaporation masks, for use across a wide range of selective vacuum chamber processes, such as the deposition of gold and silver on various substrates.
Tecan has developed high-performance evaporation masks, for use across a wide range of selective vacuum chamber processes, such as the deposition of gold and silver on various substrates Significantly more durable and accurate than traditional types, the masks represent excellent value for money and will typically withstand the post-deposition cleaning process for up to ten times longer, keeping replacement costs to a minimum

Tighter tolerances for nickel evaporation masks
Tecan has developed a range of high-performance nickel evaporation masks, for use in a range of selective vacuum chamber deposition processes, such as gold and silver plating on silicon.
Evaporation masks last longer
Tecan has new surface plating options for its high-performance evaporation masks, delivering significant increases in operational life by virtually eradicating damage from current cleaning processes.
Using electroforming and photo-etching techniques, the company produces tightly costed nickel and magnetic stainless-steel masks which out-perform traditional photo-etched molybdenum.
The technique combines low tooling costs with superior tolerances, delivering greater density designs with higher accuracy aperture edges.
Multilevel masks can also be produced, with 'stepped' recesses, limiting the need for spacer sheets in multiple-sheet sets, if required.

Evaporation masks, for use across a wide range of selective vacuum chamber processes, have been further enhanced by Tecan - combining coplanar rigidity with optimum aperture accuracy.
Can-on-board solder migration problems solved
Tecan Components has solved a range of problems associated with automated soldering of RFI screening cans/fences onto PCBs with the introduction of the 'Plimsoll line and lattice bridging stencils'.
Cost-effective single masks, traditional multimask sets and stepped masks are available to meet the individual needs of all custom designs.
During manufacture, masks are subjected to computerised co-ordinate measuring as part of the company's rigorous statistical process control (SPC) 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.
Time and costs are saved, and traceable quality control with hard copy back-up documents, is assured.
An established ability to fabricate all mask types ensures established 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 magnetic 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 be supplied.
Evaporation masks are used to fabricate a wide number of simple and complex microengineered electronic components and products, for single and multilayer applications in industrial, aerospace, automotive, medical and pharmaceutical markets.
For example, evaporation-depositing gold or silver contacts onto quartz crystal oscillator tracks and automotive thermocouples.
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.
