Q Step 6 Phosphor-Encapsulant Preparation and Dispensing
A To achieve white light emission by converting the blue light from the LED chips through wavelength conversion using a phosphor mixture, and to simultaneously protect the fragile COB circuits. This process precisely determines the final lamp's Correlated Color Temperature (CCT) and color rendering properties.
-
Q Step 7 Curing Oven
A After the phosphor-encapsulant is dispensed onto the COB strips, the strips are carefully transferred into a curing oven for 2hours, transforming it from a liquid or gel state into a solid, durable, and transparent protective layer.
-
Q Step 8 In-process Test
A To identify and rectify any defects (such as short circuits, open circuits, or faulty components) that may have occurred during the previous manufacturing steps, ensuring that every COB LED strip meets its specified electrical and functional requirements.
-
Q Step 9 Automatic Machine for Adhesive Tape
A Automaic machine will aligns the 3M double-sided adhesive tape precisely with the back of the flexible COB strip PCB
-
Q Step 10 Customized Length per request
A our workers will cut cob led strip into different length, which requested by customers.
-
Q Step 11 Aging Test & QC Test
A Aging Test
100% of the finished COB strips that have passed all previous tests are powered on and placed into an aging room for 4hours to check if any failures
QC Test
Visual Inspection: Checking for uniform illumination, absence of dark segments, color consistency, and physical defects like bubbles or contamination in the encapsulant.
Basic Electrical Test: Verifying that the cob strips draw current within the specified range and do not short circuit.
Photometric Check: Assessing whether the light output, color temperature (CCT), and chromaticity meet the required specifications.
-
Q Step 12 Package & Shipping
A After cob strips are passed all the test, our workers will pack it into the carton and transported to finished goods warehouse. Now our cob led strip is waiting for shipping agent's pick up.

Q Flexibility and Durability
A COB led strip lights are much more flexible than other flexible strips because of the small size of the diodes and the uniform weight distribution. These diodes are so small and closely spaced that no point of the strip is the same. This uniformity makes it easy to set up the strips without planning around a 5050 SMD LED sticking out where you don’t need it. This extra flexibility will make it easier for them to fit into tight areas and turn corners in your application.
