New Machine Concept for Electronics Fabrication

Name: New Machine Concept for Electronics Fabrication
Brand: SCANLAB GmbH

Posalux SA has introduced a newly designed machine for electronics fabrication that employs SCANLAB GmbH’s highly integrated precSYS 5-axis scan sub-system. The Swiss manufacturer’s laser processing system is specifically tailored to demands of micromachining and is also usable for processing such challenging materials as polymers and ceramics. The machine features precSYS, which enables ultra-precise, highly dynamic beam deflection for guiding the laser spot onto workpieces. New standards in micro-drilling precision are set by results obtained for fabricating electronics test equipment, where bore hole corner radii smaller than 5 µm are now possible. A key component of probe cards are their guide plates. They contain a mechanically stable substrate with thousands of micro-bore-holes through which the probe card’s contact pins must be safely and precisely guided to facilitate subsequent reliable contact with the semiconductor device’s connectors. Substrates are made of ceramics. And it is exactly this material that is so challenging to process.

Greatest Flexibility Combined with Intuitive Operation Posalux’ laser processing machine specifically addresses these requirements. The integrated sub-system by SCANLAB, coupled with an ultra-short-pulse (USP) laser, enables processing of highly diverse materials such as metals, polymers and ceramics, without affecting them thermally. The scan solution provides five axes for defined laser beam guidance in the machine’s x,y,z coordinate axes and a simultaneous superimposed, adjustable angle of incidence (positive or negative). This makes it ideal for fabricating micro-bore-holes with high aspect ratios and freely definable geometries. And the intuitive user interface lets machine operators easily load a bore image, assign process parameters and scan the workpiece surface.

Industry insiders are well aware of the imperative to create ever-smaller bore geometries. This makes it all the more impressive that Posalux’s precSYS infrared machine already fulfills application specifications previously thought only possible at green wavelengths.
