Overview

Four Core Customization Capabilities

Hongyi's Customization Center integrates four core capabilities — thin-film metallization, precision machining, custom packaging and testing services — covering the full process chain from substrate to finished product. Our engineering team works alongside you to translate your design precisely into a production-ready product.

Thin-Film Metallization
Thin Film Metallization

Thin-Film Metallization

Using vacuum sputtering, evaporation and photolithographic patterning, we deposit precision metal films of 0.05μm ~ 5μm on ceramic, alumina, AlN and similar substrates — meeting next-generation thermal management, optical and RF packaging applications.

  • Multiple alloy systems: Cr / Ni / NiCr / Au / Pt
  • Pattern accuracy ±5μm, film thickness uniformity ≤ 3%
  • Supports large substrates 50.8mm × 50.8mm ~ 200mm × 200mm
  • ROHS / REACH compliant throughout the process

Process

Five-Step Customization Process

From requirement to delivery, every step has a dedicated engineer assigned — fully transparent and traceable end-to-end.

01
Requirement Discussion

An engineer aligns with you on technical details — power, resistance, package, environmental specs and other key parameters.

02
Solution Design

Based on your application, we provide an initial solution, simulation and cost estimate within 5 business days.

03
Sample Build

After solution sign-off, engineering samples are delivered within 2–4 weeks with a complete test report.

04
Mass Production & Delivery

Production runs with full incoming, in-process and outgoing inspection — delivered to your schedule.

05
Continuous Improvement

Process and quality are continuously refined per usage feedback — supporting long-term cooperation and technology upgrades.

Frequently asked questions

What kinds of customization does Hongyi offer?
Four core capabilities: (1) thin-film metallization for special electrical characteristics, (2) precision machining for non-standard dimensions, (3) custom packaging and terminations, (4) full reliability testing per customer specification. We can deliver special resistance values, custom power ratings, non-standard packages and full integrated cabinet solutions.
How long does a custom project take from inquiry to mass production?
Typical timeline: requirement discussion (1 week) → engineering review and quote (1 week) → tooling and sample production (2–4 weeks) → customer sample approval (varies) → mass production (3–6 weeks). Total 8–12 weeks for moderate complexity. Simple variants on existing platforms can ship samples in 1–2 weeks.
Is there a tooling fee for custom resistors?
Tooling cost depends on complexity. Variants on existing tooling (different resistance value, same package): no extra fee. New mechanical packages: typically $300–$2,000 USD one-time, often waivable for orders above 5,000 pieces or recurring annual volumes. Quote includes a clear breakdown.
Do you sign NDAs for confidential designs?
Yes. We routinely sign mutual NDAs covering both your design files and our process know-how. Either party's standard NDA template works; we can also use a Hongyi template with mutual review. Once signed, all customer-supplied files are stored on access-controlled internal systems and shared only with the assigned engineering team.
Can you handle low-volume custom prototype runs?
Yes — prototype quantities from 5–20 pieces are routine for engineering validation. We do charge cost-recovery for prototype runs (typically $50–$300 per piece depending on complexity) but waive that fee once you commit to a production order. We've prototyped resistors for university labs, startup R&D and aerospace one-offs.
What file formats do you accept for custom drawings?
We work with PDF (preferred for review), DWG/DXF (AutoCAD), STEP/IGES (3D models), and dimensioned spec sheets in any common format including hand-sketched concepts. For electrical specs, we accept Excel BOMs or plain-text part lists. Send via email or any file-sharing link in your inquiry.
