PCB Buffer
■ Can identify NG bad, OK, no board 3 status
■ Number of storage boards: 20pcs
NeoDen SMT Buffer is an automatic conveyor system designed to temporarily store and manage PCBs between different SMT production stages. By absorbing speed variations between machines, it helps maintain smooth material flow, prevents congestion, and provides temporary staging for post-reflow cooling and production optimization.
The system supports FIFO (First-In-First-Out), LIFO (Last-In-First-Out), NG/OK sorting, and pass-through modes, making it suitable for a wide range of SMT production lines.

Why Use an SMT Buffer Conveyor?
Differences in machine cycle times often create bottlenecks in SMT assembly lines. A buffer conveyor acts as a temporary storage station between processes, allowing upstream and downstream equipment to operate more efficiently.
Typical applications include:
- Line balancing between machines with different processing speeds.
- Post-reflow cooling and temporary board holding.
- Production optimization during downstream pauses or slowdowns.
- Flexible FIFO and LIFO production management.
- OK/NG board sorting after SPI or AOI inspection.

Key Features of NeoDen SMT Buffer
1. Double Ball Screw Elevating Structure
NeoDen Buffer adopts a double ball screw structure for vertical movement. This design provides stable rising and falling operation while enabling automatic PCB storage and transfer between different levels.
2. PLC + Touch Screen Control System
The NeoDen SMT Buffer utilizes a PLC and touch screen control system for easy operation and convenient parameter settings, allowing operators to manage the equipment efficiently.
3. Multiple Operating Modes
One machine integrates several production flow modes:
- FIFO (First-In-First-Out)
- LIFO (Last-In-First-Out)
- Pass-through mode
- NG/OK sorting mode
These functions provide greater flexibility for different production requirements and process arrangements.
4. NG, OK and No-Board Status Identification
The system can identify three operating statuses:
- NG board
- OK board
- No board
When connected with inspection equipment such as SPI or AOI systems, the buffer can support automatic board flow management and sorting.
5. Standard SMEMA Interface Compatibility
NeoDen Buffer is compatible with the SMEMA interface standard, enabling integration with upstream and downstream SMT equipment for automated production lines.
