· Core Component Advantages
LED Chips: Selected high-brightness LED chips provide stable lumen output, good consistency and reliable performance under continuous operation.
IC / Integrated Circuit: Constant-current control helps stabilize power output. Protection design can improve operating reliability when used within the specified electrical conditions.
Capacitor: Selected capacitors with suitable voltage endurance and temperature rating support smoother operation and longer service life.
Inductor / Transformer: Copper winding and a matched magnetic core help provide stable current control and reliable electrical performance.
PCB Board: Aluminum PCB construction supports heat dissipation and stable operation of the LED and driver components.
Our DOB: Higher-specification LED chip solution, matched inductor/transformer, selected capacitors and a thicker aluminum PCB can provide better consistency and long-term stability when these specifications are confirmed for the product.
· SMT Production & Quality Control
DOB modules are produced through a standardized SMT manufacturing process. Controlled solder paste printing, component mounting, reflow soldering, electrical testing and visual inspection help improve batch consistency before packing.
Process: PCB loading → Solder paste printing → LED/component mounting → Reflow soldering → Electrical test → Visual inspection → Packing
