Semiconductor Prototyping: Cleanroom Parts
In vacuum and cleanroom work, outgassing and particle generation matter as much as the dimension.

What actually goes wrong in semiconductor & electronics
These are the three problems that decide whether a semiconductor & electronics prototype succeeds or gets scrapped on arrival.
Outgassing in a vacuum environment
A polymer that is fine in an enclosure can outgas in a vacuum chamber and degrade the pump. Material choice and conditioning time are the deciding factors, and they have to be specified.
Particle generation
Aluminium and stainless are standard where particles are critical. A coated or plated part can shed at the coating boundary, so the finish has to be specified with the application.
Flatness and parallelism on a vacuum flange
A flange that does not seal leaks, and a leak costs more than the part. Flatness and parallelism are more demanding than a general tolerance callout.
Our approach on semiconductor & electronics parts
- 01 We ask about the vacuum level, the base pressure and the cycle time before recommending a polymer, and we say no when a polymer will not work.
- 02 For a vacuum application we will machine the flange face in one setup and check flatness with a granite surface plate.
- 03 Parts for a cleanroom are handled and packed to minimise particulate recontamination.

A prototype answers geometry and fit. It does not qualify a product, and we will not pretend otherwise. These are the questions that need a test programme.
