Customed-made Alu 1.5 OZ Multilayer Lighting LED PCB Assembly Service

LED PCB Assembly refers to the process of mounting, soldering and electrically connecting light-emitting-diode (LED) packages and their driver/control components onto a printed circuit board (PCB) that has been specially designed for high heat dissipation, enabling the finished module to be powered and emit light immediately. Unlike conventional PCBA, LED PCB Assembly focuses on opto-thermal-electrical co-design:

• Substrate & thermal management
  • Aluminum-core (MCPCB), copper-core or ceramic substrates conduct heat away from the LED junction
  • Thick copper planes, thermal vias and TIMs lower the junction-to-ambient thermal resistance
• Optical requirements
  • High-reflectivity white solder-mask (≥88% reflectance) maximizes light output
  • Phosphor dispensing or color-bin matching controls chromaticity and CRI within specifications
• Typical process flow
  • Incoming inspection → solder-paste stencil printing (optimized for thermal pads) → high-speed pick-and-place (polarity check) → reflow soldering (peak 240-255°C, nitrogen atmosphere) → AOI/AXI → selective wave (if THT parts) → optical & electrical test (luminous flux, color temp, junction temp) → burn-in → conformal coating (lens area masked) → final QC & pack
