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.
Using electroforming techniques, the company is able to produce tightly costed sheet masks which out perform traditional photo-etched molybdenum which has limits on how small, or defined, apertures may be.
The method allows the production of far tighter tolerances, so that greater density designs with higher accuracy aperture edges are produced.
So robust is the Tecan mask, that it will typically withstand the post-deposition cleaning process for up to ten times longer than other masks - significantly reducing the need for replacements.
Single masks, and multi-mask sets are available to meet the individual needs of custom designs.
Evaporation mask techniques are used to fabricate a wide number of simple and complex micro-engineered electronic components and products, for single and multi-layer applications in industrial, aerospace, automotive, medical and pharmaceutical markets.
For example, evaporation-depositing contacts onto quartz crystal oscillators and the fabrication of similar components, onto substrates such as silicon or glass.
The systems cost-effectively cater for development, prototyping, small, medium and large-scale production applications - affording consistently accurate results.
