Outgoing Quality Control(OQC)
OQC is the quality of the products before delivery management, focuses on the state of the packing of the goods, anti-collision materials, product identification, safety signs, Accessory Kits, user manual, product performance test report, carton label, etc., a comprehensive inspection, to ensure customer agreement and when receiving content conform to the agreement.LED Corn Bulb 20W E27
Inspection items include:
A. Packaging inspection of finished products: whether the packing is firm, whether it meets the transportation requirements, etc.
B. Inspection of finished products: if the trademark batch number is correct.
C. Appearance inspection of finished products: whether the appearance is damaged, cracked, scratched, etc.
D. Functional inspection of finished products.LED Corn Bulb 20W E27
LED chips have two basic structures, transverse structure and vertical structure.
The two electrodes of the transverse structure LED chip are in the same side of the LED chip, and the current flows in an equal distance between the n-and p-type limits.
Vertical structure of LED chips, two electrodes on both sides of the LED epitaxial layer respectively, because of the graphical electrode and all p - type restrictions as a second electrode layer, make almost all current through the LED epitaxial layer, vertical rarely transverse flow of current, can improve the current distribution of the flat structure, improve the luminous efficiency, also can solve the problem of p of shading, improve the LED light emitting area.
