Precision Circuit Imaging & Etching Technology

UGPCB Factory demonstrates exceptional process control in circuit patterning and etching. For standard PCB production, we consistently achieve:

• Laser Direct Imaging (LDI) replacing traditional photolithography masks, enabling digital file-based exposure with ±5μm alignment accuracy
• Alkaline etching process ensuring clean line edges with ±15% line width control (industry-leading tolerance)
• Expertise in handling various copper thicknesses (1oz-6oz) with minimized side-etching

High-Precision Drilling & Hole Metallization

Our drilling capabilities cover:

• Mechanical drilling for 0.4mm-3.0mm boards with ±0.025mm hole size tolerance
• Laserbohrung down to 0.1mm microvias
• Hole metallization Erreichen >20μm uniform copper plating through advanced chemical deposition and electroplating
• Special processes for 8:1 Zu 10:1 aspect ratio requirements

Multilayer Lamination & Interlayer Alignment

• Up to 100-layer PCB fabrication using FR-4 Grade A materials
• Precision lamination with ±0.05mm layer-to-layer alignment
• Temperature/pressure/time-controlled processes preventing delamination
• Options for high-Tg materials, high-speed laminates, and heavy copper up to 1000μm

Lötmaske & Surface Finish Options
