Capabilities and Scope

Processes & Materials

  • CNC turning, CNC milling, multi‑axis machining, deburring, finishing, inspection support
  • Kovar / ASTM F15 (Fe‑Ni‑Co) and related grades per drawing

Part Sizes & Quantities

  • Small to medium components typical of hermetic packages
  • One‑off prototypes through repeat low‑volume batches

Tolerances and Finish

Held per drawing. Focus on tight dimensional control, flatness on sealing faces, and burr‑free edges. Discuss critical features during RFQ. Note: Secondary processes (plating, heat treatment, surface prep) can be aligned if specified at RFQ.

DFM Guidance for Kovar and Fe‑Ni‑Co Alloys

Kovar machines differently than common steels or aluminum. Consider these guidelines to improve outcomes:

Sealing surfaces: Define flatness, parallelism, surface roughness; call out edge break or radius.
Burr control: Specify standards (“no measurable burr”) on critical features; avoid over‑polishing.
Thin walls & small features: Provide minimum wall thickness targets; add generous corner radii.
Threads & counterbores: Include standards, tolerances, thread reliefs; note sealing/venting needs.
Datums & inspection: Establish functional datums; call out measurement methods for flatness, runout.
Drawing clarity: Include material grade (e.g., ASTM F15), condition, cosmetic zones, handling notes.

Quality, Traceability, and Documentation

Material Certification

Heat/lot traceability for Kovar / ASTM F15.

Dimensional Inspection

Focused Inspection

Sealing features, flatness, surface finish.

Controlled Deburring

Cosmetic inspection for hermetic packages.

Certificate of Conformance

First‑article style reports on request.

Protective Packaging

Clean packaging to safeguard sealing faces and edges.

Who This Service Is For

Best Fit

  • Teams needing custom Kovar housings, lids, rings, frames, flanges, or complex parts
  • Projects requiring tight‑tolerance CNC machining, thin‑wall/small‑feature control, burr‑free finishes
  • Programs that value DFM feedback, documentation, and reliable repeatability over lowest unit price
  • Buyers needing material certification, traceability, and clear English communication

Not a Fit

  • Projects seeking only the lowest quote without quality or specialization
  • Very high‑volume commodity work with no precision or material specificity
  • RFQs without drawings, dimensions, quantities, or application context
  • Requests for material substitutions without engineering validation

FAQs

Do you support first articles before production release?

Yes. We routinely provide first‑article style documentation on request and lock down process controls for repeat orders.

Can you help improve a design before machining?

Yes. We provide practical DFM guidance focused on Kovar’s machining behavior, sealing features, and burr control.

What quantities do you support?

One‑off prototypes through repeat low‑volume batches. Share your forecast or expected reorder cadence if available.

What about inspection and traceability?

We provide material certs (heat/lot traceability) and dimensional reports aligned with your drawing and inspection scope.

What affects price and lead time?

Material availability, part size and complexity, thin‑wall risks, tolerance/finish requirements, inspection scope, and batch size.
