High Quality PCB FIFO LIFO Buffer Vertical PCB Stock Buffer With SMEMA Compatible

The HS‑HC series Vertical Stock Buffer is engineered to serve as an intermediate buffering station between SMD placement machines and AOI inspection equipment within SMT production lines. It temporarily stores PCBs to balance production tact time, resolve line‑stop bottlenecks from upstream or downstream equipment, and ensure a continuous, stable circuit‑board manufacturing workflow. Fully SMEMA‑compliant, this unit seamlessly connects with mainstream SMT machinery.

• User‑friendly soft‑touch touch‑screen control panel for easy parameter setup and status monitoring.
• Multiple working modes selectable: FIFO, LIFO, Loader, Unloader and Reject mode to match diverse production requirements.
• Fast, smooth and precise indexing movement for stable PCB transfer.
• Built‑in internal PCB magazine rack, maximum storage capacity up to 25 pieces of PCBs.
• On‑board display indicates OK / NG status for each stored PCB layer.
• Upper conveyor platform supports double re‑check for NG defective PCBs.
• Equipped with threshold setting system for flexible production configuration.
• Standard SMEMA signal communication interface for quick integration into existing SMT lines.
• Optional function: Automatic width adjustment.

Applied in SMT assembly lines, placed between SMT pick‑and‑place machines and AOI inspection systems. When downstream inspection equipment pauses operation, the buffer machine receives and stores incoming PCBs; when upstream equipment stops, it releases stored boards to keep the subsequent process running, minimizing production downtime.
