Custom Precision Parts
Tuguan Semiconductor’s core business is drawing-based custom fabrication. Most semiconductor process components are application-specific — we manufacture to your engineering drawings, CAD files, or physical samples.
How to Order Custom Parts
Option A — Engineering Drawing
Submit a 2D drawing (PDF, DWG, DXF) with:
- All critical dimensions and tolerances
- Surface finish requirements (Ra or equivalent)
- Material specification (grade, purity)
- Any special requirements (He leak test, XRD, ICP-OES)
We will review within 1 business day and issue a quotation with lead time.
Option B — CAD File (3D Model)
Submit a STEP or IGES 3D model. Our engineers extract a 2D working drawing for your approval before production begins.
Option C — Reverse Engineering (Physical Sample)
Send a worn or broken component for measurement. We will:
- Measure all dimensions using CMM and profilometer
- Identify material by XRF or visual inspection
- Generate a 2D drawing for your approval
- Manufacture exact replacements
Design for Manufacturability Support
Our application engineers can advise on:
| Topic | Guidance |
|---|---|
| Tolerance assignment | Which tolerances are achievable vs. unnecessarily tight |
| Wall thickness minimums | Structural limits for drilling and thin-wall sections |
| Corner radii | Minimum achievable internal radii |
| Surface finish requirements | What Ra is actually needed for each surface |
| Material selection | Which grade offers the best performance/cost trade-off |
This service is free — we prefer to get the design right before production begins.
