Step 01
Raw Material Inspection
Incoming inspection (IQC) for bare LED chips, flexible printed circuits (FPC), IC chips, and solder alloys to verify conductivity and binning purity.
Production Excellence
Automated LED Manufacturing Facility in Shenzhen
Shenzhen Livdo Lighting Technology Co., Ltd. operates a 2,053 m² state-of-the-art facility certified onsite by SGS Group. Founded in 2014, we specialize in end-to-end manufacturing of continuous FCOB flexible LED strips, addressable RGB/RGBW pixel strips (WS2811, WS2812B, WS2815, SK6812), and intelligent SPI/PWM controllers.
Equipped with high-speed SMT lines, automated phosphor dispensing, multi-zone reflow ovens, and dedicated burn-in aging racks, our facility maintains rigorous standard operating procedures (SOP) to ensure zero-defect shipment for engineering projects, brands, and distributors globally.

Step 01
Step 02
Solid Crystal (Die Bonding)
High-precision placement of bare flip-chips onto FPC pads ensuring thermal dissipation and structural adhesion.
Step 03
Phosphor Dispensing
Automated linear phosphor coating over continuous flip-chip arrays to deliver continuous dot-free FCOB linear light output.
Step 04
Tin Pasting (Stencil Printing)
High-precision stencil printing of lead-free solder paste onto flexible PCB pads for strong, reliable electrical joints.
Step 05
SMT Pick & Place
High-speed SMT placement of SMD LEDs (2835, 5050), driver ICs (WS2811, WS2815, SK6812), capacitors, and resistors.
Step 06
Reflow Soldering
Multi-zone thermal profile reflow soldering guaranteeing void-free solder joints without thermal stress to delicate LED packages.
Step 07
In-Line Testing 1
Immediate post-reflow electrical testing to identify and rectify short circuits, open circuits, or missing component solder joints.
Step 08
PCB Cutting & Assembly
Precision panel cutting along designated cut marks to prepare custom PCB strip lengths for soldering and extrusion.
Step 09
Wire Soldering
Manual or automated soldering of input/output wires, 3-pin/4-pin JST connectors, or waterproof terminal cables according to buyer specifications.
Step 10
Full Burn-In Aging
Continuous full-power burn-in aging for hours to stress test thermal stability and eliminate early-life electrical failures.
Step 11
Reel Rolling
Controlled tension winding of continuous 5m/10m LED strips onto plastic spools without bending or stressing solder points.
Step 12
Final QC Inspection
Comprehensive visual and optical checks for CCT consistency, lumen output, 3M adhesive backing, and IP silicone seal integrity.
Step 13
Anti-Static Packaging
Sealing in anti-static moisture-barrier aluminum bags with desiccant packs, private labels, and reinforced export cartons.
Step 14
Finished Goods Warehouse
Inventory staging under climate-controlled conditions, ready for prompt air, sea, or express export delivery worldwide.
