SMT Depaneling Machine — Automated PCB Separation for Production Lines

Inline Conveyor Depanelers

Fully integrated into your SMT line with SMEMA-compatible conveyors. Panels flow automatically from upstream equipment through depaneling to downstream processes — zero manual handling required.

• KL-4500U Inline Depaneling System →
  Curve routing + SMEMA conveyor, high-volume SMT lines
• KL-4500X Inline Depaneling System →
  Extended format inline, larger panel processing

Stand-Alone SMT Routers

Flexible batch-processing depanelers with dual worktables and automated path programming. Ideal for mixed-product lines, prototype runs, and operations that don't require continuous conveyor flow.

• KL-3500II Curve Router →
  60,000 RPM, dual worktables, 4-axis routing
• KL-3500WII Curve Router →
  Wide-format for larger panels
• KL-3530 Curve Router →
  Mid-range precision, cost-effective entry
• KL-3530S Curve Router →
  Compact footprint, limited space SMT lines

What is an SMT depaneling machine?

An SMT depaneling machine is a PCB separation system designed to integrate into surface mount technology (SMT) production lines. It receives populated PCB panels from upstream equipment via SMEMA-compatible conveyors, performs precision cutting or routing to separate individual boards, and passes them downstream — all without manual intervention. SMT depanelers can operate inline (conveyor-integrated) or as stand-alone units with automated loading.

What is SMEMA compatibility in SMT depaneling?

SMEMA (Surface Mount Equipment Manufacturers Association) compatibility means the depaneling machine follows the standard interface protocol for SMT line communication. This allows the depaneler to exchange board-ready and machine-ready signals with upstream and downstream equipment, enabling seamless automated conveyor operation without manual board handling.

Inline vs stand-alone SMT depaneler — which should I choose?

Choose an inline SMT depaneler (KL-4500U/KL-4500X) if you need fully automated, continuous production with conveyor integration — ideal for high-volume lines. Choose a stand-alone curve router (KL-3500II/KL-3530) if you need flexibility for batch changes, multiple fixture setups, or lower-volume production that doesn't require continuous conveyor flow. Stand-alone units are also more cost-effective as an entry point.

Can SMT depaneling machines handle different PCB thicknesses?

Yes. Keli Smart SMT depanelers accommodate a range of PCB thicknesses. Curve routing machines typically handle 0.6mm to 3.5mm boards, while UV laser systems can process even thinner flexible circuits down to 0.1mm. Inline systems feature adjustable conveyor rails and fixture systems to accommodate various panel sizes and thicknesses.

How does MES integration work with SMT depanelers?

Keli Smart SMT depanelers support MES (Manufacturing Execution System) connectivity via standard network protocols. The machine can report production counts, alarm states, and processing status to the central MES, enabling real-time production monitoring and traceability. This integration helps maintain quality control and supports Industry 4.0 smart factory initiatives.
