Semiconductor & Test

Vacuum, chamber and clean-environment parts for semiconductor equipment and test handlers.

Semiconductor work is less about the tolerance than about what the surface must not do: outgas, shed particles, or trap the chemistry that runs over it. A part can measure perfectly and still fail because a blind hole kept a burr or a finish holds moisture.

We machine chamber components, test sockets, probe-card hardware, handler fixtures and vacuum fittings, mostly in aluminium and stainless, with cleaning and packaging treated as part of the process rather than an afterthought.

Typical work: low to medium volume, high mix, where cleaning and documentation carry as much weight as the tolerance.

How the work runs

From drawing to shipping, in this order.

Cleanliness reviewWhether the part sees vacuum, plasma or a cleanroom decides the material, the finish and the packing.

MachiningParts machined with dedicated tooling; no coolant residue left in blind holes or threaded features.

Clean and checkUltrasonic cleaning, then flatness, hole position and surface finish measured and recorded.

PackParts bagged individually, with the report and the certificate inside the box.

Materials, equipment and inspection

The practical detail.

Materials and environment

6061 and 7075 aluminium, 316L and 304 stainless, titanium, PEEK, PTFE and machinable ceramics where the drawing allows. Surface finish specified as Ra; anodising and passivation arranged to the drawing.

Inspection

CMM for geometry, profilometer for surface finish, and visual inspection under magnification for burrs and edge quality. Parts bagged individually where the drawing or the customer requires it.

Quality and documentation

Capacity

What the department can actually hold.

Part family	Typical material	What decides the price
Vacuum chamber parts	6061-T6, 316L	Flatness, finish and leak-check requirement
Test handlers and probe stations	7075, 6061	Hole position and thin-wall stability
Wafer handling end effectors	6061, PEEK	Weight, flatness and edge finish
Gas and fluid manifolds	316L, aluminium	Internal finish and passage cleanliness
Insulating components	PEEK, PPS, PTFE	Machining parameters and dimensional stability
Frames and brackets	6061, 7075	Anodising class and colour match

A clean part is not the same as a clean process. If the part goes into vacuum, say so — the deburring, cleaning and packing change with that one sentence.

Where the money goes

What actually drives the price of this work.

Finish callout Ra 0.4 on a sealing face is normal; Ra 0.4 on every face is a polishing job you did not need.
Flatness A 0.01 mm flatness on a 300 mm plate is achievable, but it needs stress-relieved stock and light finishing passes.
Cleaning and packing Ultrasonic cleaning and individual bagging are real costs, and they are cheaper than a rejected lot at the customer's dock.
Material certification Some buyers need mill certificates and a material lot number on the box. That is a documentation cost, not a machining one.
Batch Prototype quantities of 5 cost five times the unit price of 200. Fixtures and programming are the reason.

Straight answers

Questions buyers ask about this work.

How do you control particles and burrs?

Deburring is a specified operation, not a final look: edges broken to the drawing, blind holes cleared, then cleaning and individual bagging where required. Acceptance criteria are agreed before the first batch.

Can you hold flatness on a large plate?

Yes, within what the process can do, and the honest answer depends on thickness and how much material comes off. Tell us the flatness and the plate size and we will quote the sequence that holds it.

Do you machine ceramics?

We machine what can be cut with diamond tooling, quoted case by case. Where the geometry is better moulded or ground by a specialist we will say so rather than take the job.
