Product overview
The Electronic cover tape coating machine from Shaanxi Beiren Printing Machinery is a precision line engineered for SMT packaging cover tapes. It combines comma blade and screen-roller coating in one platform, supports up to 120 m/min production speed, offers ESD-capable construction and configurable multi-stage drying to meet optical-clarity and peel-force targets. The machine handles multiple coating widths and large rolls for continuous high-yield operation.

Key features

• Integrated dual coating: comma blade coating and screen roller coating in one machine for process flexibility
• High throughput: up to 120 m/min operating speed
• Multiple coating width options: 1350 / 1650 / 1950 mm
• Large unwind/wind capacity: long-run roll handling (Φ1000 mm unwind, Φ1200 mm rewind)
• Multi-stage drying ovens with selectable heating sources to control solvent evaporation and minimize haze
• Designed for functional coatings including anti-static, conductive and anti-fog formulations

Advanced coating technology

• Comma blade system: suitable for coating weights of 30–70 g/m², for thicker adhesive layers with stable film build
• Screen roller system: suited for 10–40 g/m² coatings, enabling thin functional layers with micron-level uniformity

Drying and oven configuration
The line uses a combined roller-type and suspended hot-air oven layout with nine staged zones to achieve controlled solvent removal and optical clarity. Heating options include hot oil, steam, hot air, natural gas and electric heating to suit process and formulation requirements.

Applications

• Heat-activated adhesive cover tapes for passive components (resistors, capacitors)
• Pressure-sensitive anti-static tapes for heat-sensitive components (LEDs, flash memory)
• Conductive and functional coatings for ESD-safe packaging and anti-fog treatments

Manufacturing, R&D and quality
Shaanxi Beiren Printing Machinery combines decades of machine-building experience with in-house fabrication of key components, dedicated R&D and process testing. Supplier services include installation support, operator training and formulation consultation to ensure consistent peel force, ESD performance and optical clarity.

FAQ (technical highlights)

• System difference: Comma blade handles heavier coating weights (30–70 g/m²); screen roller covers thin, precise layers (10–40 g/m²); both are integrated to allow switching without separate lines.
• Drying options: hot oil, steam, hot air, natural gas, electric; multi-stage oven (9 zones × 4 m) optimizes solvent evaporation.
• Available coating widths: 1350 mm, 1650 mm, 1950 mm.
• Technical support: R&D team offers installation guidance, operator training, formulation advice and troubleshooting.
