NG Buffer | PCB Handing Buffer
The NG Buffer is designed to effectively manage and store non-conforming (NG) PCBs in SMT production lines. This system ensures that defective boards are handled efficiently, minimizing disruptions to the production process.

- Description
Description
-
Configurable Thermal Management
-
Optional Cooling System: On-demand active cooling mitigates thermal stress on defect boards post-inspection (AOI/SPI).
-
Document Reference: Explicitly listed as optional , contrasting with dedicated Cooling Buffer.
-
-
Dynamic PCB Pitch Configuration
-
4-Step Indexing Pitch: Selectable 10/20/30/40mm spacing accommodates mixed-product lines. Validates against standard pitch options across Loader/Unloader series .
-
Critical Application: Isolates NG boards without disrupting line flow.
-
-
Industrial-Grade Control Interface
-
Sealed Membrane Panel: IP-rated touch interface resists flux/dust ingress. Correlates to Vertical Buffer’s robustness .
-
Operational Efficiency: Enables rapid mode switching during high-volume production.
-
-
Adaptive Material Flow Logic
-
FIFO/LIFO/Pass-through:
-
FIFO: Prioritizes earliest NG boards for rework.
-
LIFO: Expedites recent defect analysis.
-
Pass-through: Bypasses buffering during calibration.
-
-
Cross-Reference: Magazine Buffer confirms identical flow logic for defect management.
-
-
Precision Mechanical Adjustment
-
Lead-Screw Width Adjustment: Manual resizing for PCB widths 250–460mm. Lower precision vs. ball screw but cost-optimized.
-
Retrieval Positioning: Guided access to NG boards reduces handling time.
-
-
Contamination-Protected Transport
-
Enclosed Roller Transmission: Sealed pathway prevents particulate deposition during storage/retrieval. Mirrors Vertical Buffer.
-
Compact Footprint: 500–580mm width (Models BF-250N/BF-330N) minimizes cleanroom space vs. Magazine Buffer.
-
-
Line Integration Standards
-
SMEMA Compliance: Synchronizes error signals with AOI/SPI and MES. Consistent with all PCB Handling products.
-
Unified Transport Height: 900±20mm ensures mechanical interoperability.
