Conventional Machining

(Laser, EDM)

Higher Part Costs

Lower Process Yield

Common Processing Defects

Subsurface Damage

Longer Process

Bullen Ultrasonic Machining

Reduced Part Costs

Higher Process Yield

Greater Design Reliability & Quality

Little To No Subsurface Damage

Reduced Downtime

We Believe You Deserve a Better Solution for your semiconductor component

Preserve Material Reliability

The substrate material’s chemical and physical properties remain unchanged – Non-thermal method results in no HAZ (Heat Affected Zone) and little to no substrate damage.

Expand Design Possibilities

Implement feature sizes not possible with laser machining on thicker substrates. Micron-level accuracy widens the range of capabilities. 

Optimize Production

Eliminate inefficiencies that slow down production and increase the cost. Trust in a faster and more cost-effective process.

BULLEN Semiconductor Capabilities
