SMT Buffer / NG Buffer

Cooling Buffer: Essential Thermal Management

The Cooling Buffer provides controlled temperature reduction for PCBs after reflow soldering. Its key features include gradual cooling to prevent thermal stress, ESD-safe material construction, adjustable conveyor speed for different thermal profiles, and compact modular design. This system ensures board stability before inspection while maintaining continuous production flow.

Cooling Buffer: Essential Thermal Management for SMT Assembly

The Cooling Buffer is a specialized conveyor system designed to provide controlled cooling for PCBs after the reflow soldering process. It ensures proper thermal management by gradually reducing board temperature before components reach subsequent handling or inspection stations.

Key Features & Functions:

Gradual Temperature Reduction: Prevents thermal shock to components and PCB substrates

Adjustable Cooling Rate: Variable speed control manages dwell time for different board specifications

Static Dissipation: Built-in ESD protection throughout the cooling path

entle Board Handling: Smooth transportation prevents component displacement during fragile post-reflow phase

Process Integration: Seamless SMEMA communication with upstream reflow ovens and downstream equipment

Critical Benefits:

Quality Assurance: Eliminates thermal stress that could cause microcracks or latent defects

Inspection Readiness: Brings boards to optimal temperature for accurate AOI and testing

Line Synchronization: Buffers boards between reflow and next processes, balancing line flow

This thermal management solution protects product reliability while maintaining production rhythm - making it indispensable for quality-conscious SMT lines.
