Locating & Mounting Interfaces
Define datum relationships, locating faces, bores and mounting patterns. Provide mating references and the inspection condition needed to verify critical geometry.
Precision for equipment
Components for Semiconductor Equipment
Machined equipment components with project-specific requirements for geometry, surface condition, cleanliness and inspection.
Subsystem · Surfaces · Acceptance
Start with the Equipment Subsystem
Requirements vary by subsystem. Identify the component’s role, controlled surfaces and operating environment so the machining, finishing, cleaning and inspection scope can be reviewed together.
Vacuum & Fluid Interfaces
Identify sealing faces, passages and controlled internal surfaces where applicable. Supply the specified leak or pressure test method, conditions and acceptance criteria for scope review.
Controlled Surfaces & Handling
Mark surfaces with particle, residue or contact restrictions. Define finish, cleaning, handling and packaging requirements for the delivery condition used by the equipment.
Geometry · Cleanliness · Records
Define the Acceptance Requirements
Specify measurable criteria and the exact records required. Customer-specific cleaning, testing, documentation and approval scope must be confirmed before order acceptance.
| Feature group | Define on the drawing | Agree for acceptance |
|---|---|---|
| Geometry & datum control | Critical dimensions, datum relationships, mating references and the required surface condition. | Inspection setup, measurement conditions and the report format for the agreed characteristics. |
| Cleanliness & surface limits | Controlled surfaces, particle or residue limits, cleaning specifications and handling restrictions. | Available cleaning scope, verification method, acceptance criteria and packaging requirements. |
| Vacuum & fluid interfaces | Sealing geometry and any specified leak or pressure tests, including conditions and acceptance limits. | Test responsibility, setup, sampling and records for the requirements applicable to the component. |
| Material records & change control | Material specification, required certification, lot identification and drawing/process change requirements. | Traceability records, approved material condition and notification or approval steps for changes. |
Machining methods & approved starting material
Plan the Machining Route
Select machining methods around geometry, material condition and controlled surfaces. Confirm the approved starting form and review any material or process change against the subsystem requirements.
CNC Milling
Review datum faces, pockets, mounting patterns and passages against machining access and workholding. Identify features that require coordinated setups or inspection.
Review manufacturing route →CNC Turning
Review rotational features, bores, shoulders and sealing interfaces against the drawing. Coordinate turned and milled features with the required datum relationships.
Review manufacturing route →Material & Starting Form
Specify grade, material condition, stock form and required material records. Any proposed alternative starting form requires review against geometry, surface and acceptance requirements.
Review manufacturing route →Finishing, inspection & delivery requirements
Surface Finishing
Define surface condition, treatment, masking and dimensions checked after finishing. Include cleaning compatibility requirements in the review.
Review requirements →Quality Planning
Agree the inspection method, specified test scope, sampling, material records and final report format.
Review requirements →Handling & Delivery
Identify protected surfaces, handling restrictions, packaging specifications and any required assembly operations before delivery.

Application context & review inputs
Prepare the Equipment Part Review
Send the drawing together with the specifications that define controlled surfaces, test methods and delivery condition. Identify which requirements apply to the part and which apply to the assembled subsystem.
Drawing package checklist
- Controlled 2D drawing and 3D model with revision.
- Critical datum relationships, mating interfaces and controlled surfaces.
- Particle or residue limits, cleaning specifications and test methods.
- Material records, finish, handling restrictions and packaging.
- Quantities, delivery schedule, inspection report format and change requirements.
Semiconductor Equipment application notes & review sequence
Application context
Semiconductor-equipment components may place special emphasis on geometric control, surface condition, cleanliness, vacuum or fluid interfaces, material traceability, and change control. Requirements differ widely by subsystem.
Engineering priorities
The RFQ should identify controlled surfaces, particles or residue limits, cleaning and packaging, leak or pressure tests, critical datum relationships, material certification, finish, handling, and the exact inspection report expected.
Process Planning
We compare geometry, quantity, material, design maturity, secondary operations and inspection requirements before recommending CNC machining, die casting, or a combined route.
Project Information
Provide the CAD model, controlled drawing, order quantities and annual demand, operating environment, critical interfaces, finish, tests, documentation, packaging, and any customer-specific quality requirement.
Coordinate the Review Steps
1. Define functional requirements
Capture the operating environment, interfaces, load, quantity, material condition, and acceptance criteria and records.
2. Select the manufacturing process
Compare material, stock or casting form, machining access, secondary operations, finishing, and production risk.
3. Verify critical characteristics
Inspect the agreed characteristics with suitable equipment, methods, sampling, and controlled records.

Before You Send the Drawing
How should cleanliness requirements be specified?
Identify controlled surfaces, particle and residue limits, cleaning methods, handling and packaging requirements, test methods and acceptance criteria. Include these requirements in the RFQ.
What application information should I share?
Describe interfaces, operating environment, loads, failure risks, demand, critical features, finish, tests, documentation, cleanliness, and packaging.
When should customer-specific quality requirements be provided?
Include applicable standards, approvals, validation, documentation, traceability and change-control requirements with the RFQ so their scope and availability can be confirmed before order acceptance.
