What is CSP LED Strip?

CSP LED strips represent the forefront of lighting innovation, offering a sleek and efficient design. These strips are characterized by their Chip Scale Package (CSP) LEDs, which are notable for their minimal size and high efficiency. The unique aspect of CSP technology lies in its packaging, with the LED package being only slightly larger than the chip itself, leading to reduced thermal resistance and enhanced durability. 

Not only do CSP LED strips stand out for their design efficiency, but they also excel in performance. The strips, mounted on a flexible PCB and coated with a distinct, translucent milky-white silicone, deliver superior luminous efficiency and consistent color quality. This is mainly due to their ability to achieve a 3-step Macadam color tolerance, setting them apart from other LED types like COB strips. Their adaptability and reliability make them a versatile choice for various lighting needs, including residential, commercial, outdoor, and automotive settings.

CSP LED Strips Production

The Manufacturing Process: How CSP LED Strips are Made

  • Step 1: Raw Material Inspection

    Quality inspection of PCB boards and LED chips, the core components of CSP LED strips, is critical. This step involves rigorously testing the materials for quality assurance.

  • Step 2: Die Bonding

    CSP LED chips and resistors are precisely placed on the PCB board using an intelligent die-bonding machine, ensuring accurate alignment essential for CSP LED strip performance.

  • Step 3: Soldering

    The CSP LED strip components are seamlessly soldered using automated reflow soldering, a process crucial for establishing reliable electrical connections.

  • Step 4: AOI Inspection and Repair

    After soldering, an Automated Optical Inspection (AOI) is performed, followed by online repairs to ensure a high yield of perfectly assembled CSP LED strips. This step is crucial for maintaining quality control.

  • Step 5: Moisture Drive-Off

    Post-inspection, the LED boards undergo a high-temperature baking process. This crucial step drives off moisture, ensuring the longevity and durability of the CSP LED strips.

  • Step 6: Encapsulation

    Using an automated dispensing machine, a protective layer is applied to the CSP LED strips. This encapsulation safeguards the components and enhances the product's overall resilience.

  • Step 7: Brief Baking

    The encapsulated LED boards are then subjected to a short baking for 15 minutes under 175°C in a 16M long tunnel oven. This process solidifies the encapsulant, securing the CSP LED strip's components in place.

  • Step 8: Extended Baking

    Following the brief bake, the LED boards undergo an additional high-temperature 175°C baking for one hour in baking oven. This extended baking ensures further solidification of the encapsulant for enhanced protection.

  • Step 9: Automatic Strips Dividing

    The precision separation of the CSP LED strips is carried out using an automatic strips dividing machine. This step ensures accurate sizing and preparation for the final application.

  • Step 10: Aging Test

    The CSP LED strips undergo extensive aging tests to guarantee stability and reliability, a critical step in ensuring long-term performance.

  • Step 11: Packaging and Final Inspection

    After completing all tests, the CSP LED strips are carefully packaged. A final inspection is conducted before dispatch to ensure that each product meets the highest standards of quality and performance.
