NEW DC 12V 5 in 1 Led Chip 5050smd 30 led/m LED Strip RGB+WW+CW Waterproof Led Strip Light

Strict Quality Control

We have a strict quality control system from raw material to finished led strips.Each step must pass strict inspection, strive to produce superior products:
1.Incoming Raw Material Inspection
Comparing incoming raw material and sealed sample in terms of class, quality grade, technical data, ensuring the consistency with purchasing requirements, thus guarantee the ensuing manufactured product fulfilling customers’ requirements.
2.Led Drying
Leds will absorb humidity when exposed to air, which requires 24H drying before SMD.
3.Light-on Test after SMD
After pasting of leds onto the PCB board, each strip panels will be powered to see if any insufficient soldering, slanted leds, and dead leds, if yes, they have to be repaired until qualified; if no, then flowing to the next stream.
4.Light-on and beating test
Strips after SMD (0.5M) should be soldered to 5M roll, after which they have to be lighted again to check if any dead leds, and together with beating test to see if leds fixed tight on pcb board
5.Aging Test
Finished products must undergo at least 8 hours’ aging test 100%
6.Light-on test of finished product
Finished product, before packing, must be lighted again after aging to check if any dead leds.
7.Pre-shipment Inspection
Proofing finished product with customers’ requirements again before shipment, to ensure the consistency of products with customers' needs.
