PCB OSP Surface Finish Machine Technology Explained

PCB OSP Surface Finish Machines apply organic solderability preservatives through automated chemical processing to create protective anti-oxidation coatings on copper circuits. This environmentally friendly solution enhances solderability while preventing copper oxidation during PCB storage and assembly operations.

Key Features of PCB OSP Surface Finish Machines:

Our advanced OSP coating systems integrate precision chemical management with automated conveyor processing to deliver uniform protective films. Key features include:

Multi-Stage Chemical Processing System‌:

  • 14-stage automated treatment including micro-etching, acid activation, and dual DI rinsing for optimal copper surface preparation
  • Precision OSP Application‌: Controlled immersion coating forms 0.2-0.5μm uniform organic film for superior solderability preservation

Automated Conveyor Integration‌:

  • Adjustable Speed Control‌: 0.5-5m/min variable conveyor speed accommodates different PCB thicknesses (0.4-3mm)
  • Precision board handling for minimum 120×80mm panels with 35mm wheelbase accuracy

Eco-Friendly Operation‌:

  • Closed-loop chemical recycling reduces consumption by 40% compared to conventional systems
  • Water-efficient design with integrated DI filtration minimizes consumption to 24-36L/min

Advanced Drying Technology‌:

  • Multi-zone drying system combines blotting, cold-air knife, and 70°C hot-air tunnels for moisture-free output
  • Prevents OSP film degradation while ensuring immediate panel stacking capability

Industrial-Grade Construction‌:

  • Chemical-resistant PP/PVDF tanks and components withstand acidic processing environments
  • Compact footprint (L14.5×W1.6×H2m) with 900mm ergonomic working height for seamless production line integration
  • Essential for high-reliability PCB manufacturing in automotive, medical, and aerospace applications where oxidation-free contacts are critical
