1.2 Million LED Tubes / Month —
A Battle-Tested SMT Solution
A high-efficiency, cost-effective Surface Mount production line designed for LED tube PCBA at scale. From PCB loader to Reflow Oven, every station is engineered for uptime, yield, and ROI — built on Southern Machinery's Shenzhen manufacturing DNA.
Why LED Tube PCBA Is Tricky at Scale
LED tubes look simple — a long, narrow aluminum or FR-4 strip populated with SMD LED chips, drivers, and connectors. But at 1.2M units per month, every micro-stop on the line costs thousands of dollars.
Long-Board Handling
LED tube PCBs run 600–1500 mm. Standard SMT conveyors don't love that. You need stable rails, dual-side support, and proper transfer at every station.
Thermal-Sensitive MCPCB
White solder-mask FR-4 or aluminum MCPCB. Excess heat in Reflow Oven causes LED color shift and delamination. Profile must be tight, repeatable, and lead-free.
Component Mix
2835/3030 LED chips (huge volumes), plus resistors, capacitors, IC drivers, and end-cap connectors. High-Speed Pick and Place for chips + multi-function placement for the rest.
Sizing the Line for 1.2M pcs / Month
No guesswork. We back-calculate from the target output, working hours, and an OEE target of 85%. Here's how the configuration falls into place.
Required theoretical Pick and Place throughput to hit the 1.2M / month target with 2 shifts × 10 h × 25 days.
= 1,200,000 ÷ (25 × 20 × 0.85)
≈ 2,824 pcs/h
Per machine (2× Pick and Place)
≈ 2,824 ÷ 0.9 headroom
≈ 30,000 CPH total
→ A pair of high-speed chip shooters covers it
with a healthy 20%+ growth headroom.
From Loader to AOI — End to End
A complete SMT front-end for LED tube PCBA. Every station picked to balance throughput, footprint, and CapEx. Optional THT / Wave Soldering modules integrate for driver boards and end-cap connectors.
Selected Modules & Key Specs
Models below are representative — final selection is tailored to your PCB size, component mix, and budget. We can also split between budget / standard / high-end configurations.
