CSP LED Strip Production: A Masterclass in Precision and Innovation

CSP (Chip Scale Package) LED strips are at the forefront of LED technology, offering unmatched brightness, efficiency, and durability. Their compact design and advanced manufacturing process ensure superior performance for a variety of applications. Let’s explore the meticulous steps involved in crafting these innovative lighting solutions.

Step 1: Raw Material Inspection

The process begins with a rigorous inspection of the PCB boards and CSP LED chips. These core components undergo strict quality checks to ensure they meet the required standards, setting the foundation for a reliable and durable product.

Step 2: Die Bonding

Using intelligent die-bonding machines, CSP LED chips and resistors are accurately placed on the PCB board. Precise alignment during this step is crucial to achieving the exceptional performance and uniformity of CSP LED strips.

Step 3: Soldering

Automated reflow soldering is used to seamlessly bond components to the PCB. This critical step ensures reliable electrical connections, enhancing the strip’s overall functionality and longevity.

Step 4: AOI Inspection and Repair

After soldering, Automated Optical Inspection (AOI) is performed to detect any defects or misalignments. Online repairs follow, ensuring a high yield of perfectly assembled CSP LED strips while maintaining stringent quality control standards.

Step 5: Moisture Drive-Off

To ensure durability, the LED boards are baked at high temperatures to remove residual moisture. This step prevents potential damage to the components and enhances the strips’ longevity.

Step 6: Encapsulation

An automated dispensing machine applies a protective encapsulation layer to the LED boards. This layer shields the components from environmental factors and mechanical stress, ensuring reliable performance in various conditions.

Step 7: Brief Baking

The encapsulated LED boards are briefly baked at 175°C for 15 minutes in a 16-meter-long tunnel oven. This process solidifies the encapsulant, securing the components in place.

Step 8: Extended Baking

To further enhance the encapsulant’s durability, the LED boards are subjected to an extended bake at 175°C for one hour. This step provides additional reinforcement, ensuring optimal protection.

Step 9: Automatic Strips Dividing

An automatic strips dividing machine precisely separates the CSP LED strips into specified lengths. This step ensures consistency and prepares the strips for their final applications.

Step 10: Aging Test

Each CSP LED strip undergoes rigorous aging tests to confirm stability and reliability. These tests simulate real-world conditions, guaranteeing that the product performs flawlessly over its lifespan.

Step 11: Packaging and Final Inspection

The final step involves a comprehensive inspection to ensure each CSP LED strip meets the highest quality standards. The strips are then carefully packaged in anti-static bags or custom-designed packaging, ready for delivery.
