SKD Service and Process
1. Core Definition
SKD (Semi-Knocked Down) is a hybrid manufacturing model between fully assembled OEM products and complete knock-down (CKD) kits. For smartwatches, SKD suppliers provide pre-integrated core modules, allowing clients to focus on final assembly and branding customization.
2. Typical SKD Kit Components
| Module | Included Components | Client Customization |
|---|---|---|
| Mainboard | Pre-soldered PCBA (MCU + sensors + BT) | Firmware flashing, functional testing |
| Display | Assembled screen + touch panel | Watch face UI design |
| Structure | Case + strap + buttons (unassembled) | Surface finishing/logo engraving |
| Accessories | Battery + charger + screws | Final assembly & packaging |
3. Key Differences vs. OEM/ODM
• OEM: Supplier delivers fully finished products (e.g., Apple Watch manufacturing)
• ODM: Supplier offers pre-designed solutions (e.g., Huami for Xiaomi)
• SKD: Provides semi-finished modules with client control over critical stages (e.g., software customization)
4. Industry Applications
▸ Startups: Validate markets rapidly without $100K+ mold costs
▸ E-commerce brands: Swap materials (e.g., eco-friendly straps for EU/US markets)
▸ Enterprise clients: Develop industry-specific software (e.g., mining worker health monitors)
5. Three Core Values of SKD
① Lower Technical Barriers
• Pre-validated hardware (e.g., Nordic chips + PPG sensors)
• No RF debugging/sensor algorithm development required
② Cost Efficiency
• 30% cheaper than full OEM (no custom molds)
• MOQ as low as 200 units (vs. 5,000+ for OEM)
③ Agile Production
• 2-3 weeks from kit to product (vs. 3-6 months for full development)
• Supports small-batch iterations (e.g., test 500 units first)
6. SKD Decision Checklist
✓ Need software control?
✓ Have basic assembly capabilities?
✓ Require fast time-to-market (<1 month)?
✓ Budget under $100K?
If 2+ apply, SKD is your optimal solution.
7. Latest Trends
• Standardized modules: Type-C compatible mainboards for multi-housing use
• Open-source support: Arduino-compatible development environments
• Hybrid models: SKD + ODM combos (e.g., custom UI on public hardware)
Case Study:
A German outdoor brand used SKD to:
① Select waterproof mainboards
② Develop proprietary altimeter algorithms
③ Customize titanium cases
Result: Launched in 6 weeks with 45% lower cost vs. traditional OEM.
Ideal for:
• Hardware startups
• E-commerce private labels
• IoT developers
