Precision Screen Printing Systems for PCB Manufacturing
Advanced screen printing solutions deliver micron-level deposition accuracy for solder masks, conductive traces, and functional coatings across PCB production and industrial applications. Core technologies include:
Semi-Automatic Printing Systems
Operating Principle: Pneumatic registration with ±25μm alignment precision ensures consistent pattern transfer through controlled squeegee pressure (4-6kg/cm²) and vacuum substrate fixation.
Key Applications:
Solder mask application on FR4 and metal-core PCBs with 50μm resolution
Legend printing for component identification with 0.1mm line accuracy
Conductive ink deposition for flexible circuits and touch panel interfaces
Fully Automated Production Lines
Operating Principle: Integrated vision alignment and dual-table operation enable 1000+ panels/hour throughput with <5μm registration drift during continuous operation.
Key Applications:
High-volume solder masking for automotive electronics manufacturing
Precision printing of EMI shielding coatings on 5G components
Multi-layer functional coatings for medical device encapsulation
Key Technical Notes:
- Variable Tension Control: Pneumatic screen stretching maintains 30N/cm² consistent pressure to prevent pattern distortion in fine-pitch printing.
- Ink Deposition Uniformity: Zoned squeegee pressure control ensures ±5μm coating thickness across 650×650mm panels.
- Material Versatility: Compatible with substrates from 0.1mm flexible circuits to 15mm aluminum plates without recalibration.
- Rapid Changeover: Tool-less screen clamping and preset profiles reduce job transitions to under 3 minutes.
