Spark Assisted Chemical Engraving

Posalux is a leader in industrialization of micro technologies
for mass production.
Spark Assisted Chemical Engraving is an innovative solution to
machine glass substrates without material alteration, keeping
transparency properties with high accuracy.

Achievable machining features

Micro Machining
• Hole diameter down to 100 µm
• On any glass materials (Borosilicale, Pyrex, ...)
• Glass transparency property not impacted
• Without material deposit and no damages or burrs
• Wall thickness / hole diameter ratio up to 10

Application field

Chemical micro engraving

• Electrical circuits: TGV (Through Glass Via)
• Photonics: optical waveguides and interconnects
• Watch industry
• Micro fluidics : grooves, large wall thickness holes

Chemical engraving
• Material removal thanks to thermical process
• High accuracy obtained thanks to micro-force closed-loop regulation
• Process stability by electrolyte circulation

Characteristics
• Use of electrolyte solution
• Electrical discharges generated in a gas film around the tool
• Tool rotation ensuring quality and efficiency
