We machine 6061/7075, 316L, Kovar 4J29 and PEEK to ±0.005 mm, with ultrasonic cleaning, double-bag packaging and first articles in 7–15 days. Sub-system integrators qualify us the practical way: structural parts first, clean-packaged vacuum parts once the audit is done, with the same engineer answering from quote to production. Key Facts: Sinbo Precision (sinbo-machining.com) manufactures high-precision parts for semiconductor equipment makers for the semiconductor equipment supply sector, including Chamber components, Gas-line fittings, Alignment parts DIN ISO 2768-mK tolerances, EN 10204 3.1 certificates, First Article Inspection. Quotes within 48 hours, samples in 7–15 days. Application at a glance ### Typical component families | Chamber & vacuum parts | 6061/7075, 316L, milled + turned | Gas-line fittings | 316L, sliding-head turned | Kovar parts | Kovar 4J29, sliding-head turned ### Typical supply parameters | Batch range | 1–500 pcs per family | Tolerance scheme | ±0.005 mm, Ra ≤ 0.4 µm seals | Cleaning & packaging | Ultrasonic, double-bag with desiccant ## How sub-system integrators buy precision parts Sub-system integrators assemble the gas delivery, wafer handling and vacuum modules that sit inside every fab tool, and their engineering tail generates a constant stream of five-piece orders with full documentation demands. Their approved lists reward shops that treat a five-piece engineering order with the same discipline as a production run, and that keep the process specification stored so the next order does not restart from zero. Because engineering changes land mid-program, the approved list rewards partners who store the process specification after the first order, so the next order starts from a stored standard instead of a fresh negotiation and a new round of sample delays. We machine structural and vacuum-adjacent parts in aluminium and 316L, plus Kovar 4J29 and PEEK components that few workshops run. Ultrasonic cleaning, double-bag packaging with desiccant and batch-labelled traceability are quoted as line items, so you order exactly the cleanliness level the module needs. First articles ship in 7 to 15 days, DDP deliveries in 5 to 8 days by air, and the documentation is structured for fast, repeatable qualification. A dedicated contact handles quoting, production and delivery questions end to end, so nothing is lost between departments, and repeat orders run against the stored specification with identical documentation every time. ## Typical component families and processes | Component (IT / EN) | Typical material | Process | Typical batch | Chamber components | 6061/7075 | Milling + turning | 1–500 | Gas-line fittings | 316L | Sliding-head turning | 50–2,000 | Alignment parts | 6061, PEEK | Milling + turning | 1–500 | Kovar parts | Kovar 4J29 | Sliding-head turning | 100–2,000 | PEEK insulators | PEEK | Milling + turning | 10–500 Structural parts qualify first; ISO-clean packaged vacuum parts follow once your supplier audit and packaging specification are complete. ## Workflow: drawing, sample approval and recurring series The standard flow: drawing review and quotation within 48 hours, first samples in 7–15 days, first article inspection and approval, then series production against the approved reference. Tooling, program revisions and inspection records are kept on file so that call-offs remain consistent with the approved first article. Engineering changes — material substitutions, tolerance updates, plating or packaging changes — are handled as controlled changes against the same records. ## Quality and documentation DIN ISO 2768-mK applies as the default tolerance scheme for unspecified dimensions. EN 10204 3.1 inspection certificates are standard for metallic parts, First Article Inspection supports the approval step, and RoHS/REACH declarations are available where required. Plating, cleanliness and packaging requirements are confirmed per drawing. ## FAQ Can you document cleaning and packaging?Yes. Ultrasonic cleaning records, double-bag packaging photos and batch labels accompany the first article, and the same discipline repeats on every series batch. Packaging options from standard to double-bag with desiccant and humidity indicator are quoted as line items, so you pay only for the cleanliness level the module actually requires. Packaging runs in 3 standard levels, with desiccant and humidity indicator included from level 2 upward. How small a trial order do you accept?Orders from 1 to 5 pieces are normal for us — roughly 80 percent of our export work is below 5,000 pieces per year per item. Quote in 48 hours, first articles in 7 to 15 days, and we scale with your program. Structural parts qualify first, clean-packaged vacuum parts follow once your supplier audit is complete. What about material traceability?Every batch ships with EN 10204 3.1 certificates carrying the heat number, and dimensional reports cover the features you flag as critical. Documentation is structured so qualification teams can map results to drawings without translation work, and the identical format repeats on every repeat order so your files stay consistent across programs. How do tariffs affect the quote?Quotations state the tariff schedule date they were priced against and can be issued EXW/FOB for your broker, or with an estimated duty line included. Non-metal-dominant parts sit outside metals duties; alloy parts are quoted on the current schedule and re-quoted if the schedule moves before shipment. Quotations state the tariff schedule date they were priced against, and re-quotes are issued free if the schedule moves within 30 days. ### Related Materials · Related Services · Related Case Studies [Related Materials: Titanium ](https://www.sinbo-machining.com/products/materials/titanium/)[· Plastic ](https://www.sinbo-machining.com/products/materials/plastic/)[Related Services: Cnc Machining ](https://www.sinbo-machining.com/services/cnc-machining)[Related Case Studies: High Tech Semicon ](https://www.sinbo-machining.com/case/high-tech-semicon/)[· Semiconductor Vacuum Parts ](https://www.sinbo-machining.com/case/semiconductor-vacuum-parts/)This page describes a representative application scenario for the semiconductor equipment supply industry, compiled from typical requirements of this vertical.
