Single-part filters meet custom needs
Single-part filters eliminate contamination due to trapped debris and avoid de-lamination at the edges, as well as providing consistent cross-sectional thickness.
Single-part filters for a diverse range of applications can be cost-effectively produced for bespoke needs using photo electro forming (PEF) and photo chemical machining (PCM) Whatever the application, from inkjet nozzles to audio baffles, or light filters to particle characterisation, Tecan can produce customised metal filters in a single manufacturing process

New wafer bumping stencil boosts yields
Electroformed wafer-bumping stencils from Tecan Stencils Limited (TSL), are being used to accurately deposit solder paste directly onto silicon wafer die.
Multi-level stencils for improved PCB manufacture
TSL manufactures multi-level stencils which deliver the distinct paste volumes required by the diversity of components used on today's electronic assemblies in a single printing action.
Unlike conventional wire-woven products, the single-part filters do not have cross-over areas.
This brings a range of benefits, including the elimination of contamination due to trapped debris, no de-lamination at the edges, consistent cross-sectional thickness and consistently accurate aperture shapes and sizes.
The processes allow both simple and complex designs to be realised which can contain apertures and matrices of varying shapes and sizes and with single or multilevel planes.
A filter could have a small number of highly-accurate and extremely fine apertures, say for an optical application, or in the case of a particulate filter, be so tiny that many millions feature on a single part, each one, for example, as small as 3 microns across.
Tecan's filters are burr and stress-free, with feature sizes and tolerances to suit individual application requirements.
Various surface textures and finishes are also possible, including bright, semibright, matt, brushed and smooth.
The company ensures the individual part is produced cost-effectively from the PEF or PCM process, or a combination of the two, to optimise its required performance characteristics.
