For companies looking to reduce production costs, improve supply chain flexibility, and build local manufacturing capability, CKD and SKD assembly models are practical and efficient solutions.

Indisplay in China Shenzhen provides complete CKD and SKD manufacturing support, helping customers move from imported components to local assembly and finished product delivery.

What Is CKD?

CKD, or Complete Knocked Down, means that products are shipped as fully disassembled components. The customer’s local factory completes the full assembly, testing, and final adjustment process.

This model is suitable for customers with strong assembly capability, skilled workers, complete production equipment, and dust free room conditions. CKD can support local manufacturing policies, reduce trade risks, and provide better long-term cost advantages in certain markets.

What Is SKD?

SKD, or Semi-Knocked Down, means that key components, such as the screen, main board, or other core modules, are pre-assembled before shipment. The customer only needs to complete the remaining assembly work, such as housing installation, accessories, and final product integration.

Compared with CKD, SKD is easier to operate and requires lower assembly complexity. It is ideal for customers who want to start localized production quickly with limited factory conditions.
CKD / SKD Production Process

1. Requirement Analysis and Material Planning

Before starting a project, Indisplay evaluates the customer’s production environment, supporting equipment, staffing, and assembly capability. Based on the actual situation, we recommend whether CKD or SKD is more suitable.

Our R&D team prepares the CKD or SKD BOM list, while the engineering team provides container loading plans, shipment quantity suggestions, detailed assembly SOP documents, and assembly videos. These materials help customers understand the full process before production begins.

2. Sample Assembly and Process Verification

According to project requirements, Indisplay assembles and verifies complete sample units. This step helps confirm the accuracy of the BOM and ensures that all components match the final product design.

We also provide complete product test reports, including optical performance testing, whole-machine performance testing, sample review reports, and reliability testing. Reliability tests may include power on/off testing, high and low temperature storage testing, humidity testing, temperature change testing, vibration testing, drop testing, and road simulation testing.

After verification, the engineering team finalizes the assembly SOP and training videos for customer use.

3. Incoming Material and Pre-Assembly Quality Control

All incoming materials are inspected before production. Key components such as open cells, power boards, main boards, light bars, touch frames, cameras, small boards, tempered glass, profiles, back plates, sheet metal parts, and cartons are checked through full inspection or sampling inspection.

For SKD projects, Indisplay can complete modular pre-assembly based on the work order and SOP. For example, most structural and functional parts can be pre-installed, while core modules such as the main board, power board, or open cell are reserved for final assembly.

During production, quality teams carry out line inspection, first-piece inspection, and vibration inspection to ensure that SKD semi-finished products meet shipment standards.

4. Packaging Design and Transport Verification

Different materials require different packaging methods. Structural parts such as profiles and sheet metal components can be packed with wooden frames to prevent deformation. Open cells are packed in original LCD packaging with pallets to make loading safer and reduce breakage risks.

For first-batch shipments, Indisplay performs simulated transport testing, including vibration and drop tests, to verify packaging reliability.

5. Final Inspection and Export Documentation

Before shipment, Indisplay conducts OQC final inspection. SKD assembly sets are randomly opened and checked to confirm quantity, appearance, labeling, and packing accuracy.

We also prepare the required export documentation, including dangerous goods declarations when lithium batteries are included, CO(certificates of origin), and HS code pre-classification documents.

6. Logistics Loading Support

To reduce transport damage, Indisplay provides container or truck loading plans. These plans show how components should be stacked and secured to prevent movement, collision, or deformation during transportation.

7. Local Assembly and Technical Support
After the goods arrive at the customer’s factory, Indisplay provides assembly SOP documents, operation videos, and remote technical guidance. If needed, engineers can also be arranged for on-site support.

This helps customers complete local assembly more efficiently and reduce production risks.

8. Feedback and Continuous Improvement

After assembly, we follow up on production time, assembly difficulties, missing materials, damaged parts, and other customer feedback.

Our quality, engineering, and production teams review the feedback and continuously improve the SOP, packaging plan, BOM list, and spare parts system. For SKD projects, we can also build a dedicated spare parts reserve to quickly replace missing or damaged components.

In summary, With professional CKD and SKD assembly solutions, Indisplay helps customers reduce logistics costs, improve local production efficiency, lower trade risks, and respond faster to market demand.

Whether customers need full component assembly through CKD manufacturing or faster modular production through SKD manufacturing, Indisplay provides reliable, flexible, and practical support for localized manufacturing.
