Application Case: Semiconductor Vacuum Fixture CNC Machining

Application context

A vacuum fixture for semiconductor handling needs flatness, sealing paths, stable material and controlled burrs. The quote should include cleaning and documentation expectations from the beginning.

This is an application case playbook, not a fabricated customer success story. It describes the engineering information a buyer should prepare and the manufacturing route FabVector would evaluate before issuing a firm quote.

Suggested manufacturing route

• Machine datum plane, vacuum grooves and hole patterns with flatness checks.
• Add PEEK inserts or isolation features where electrical or thermal separation is needed.
• Clean, deburr and package according to the contamination risk.

Material and finish decisions

• Stable aluminum tooling plate for flat fixtures.
• PEEK for insulating or chemical-resistant contact features.
• Electroless nickel plating when wear and corrosion control are required.

Quality and risk controls

• Vacuum grooves require depth, width and surface finish control.
• Sharp burrs near wafers, films or optics are unacceptable.
• Flatness should be tied to a datum and inspection method.

What to include in the RFQ

• Vacuum map, surface roughness, flatness and hole pattern drawing.
• Cleanliness, bagging and handling requirements.
• Material certificate and inspection report requirements.
