Precision Circuit Imaging & Etching Technology
UGPCB Factory demonstrates exceptional process control in circuit patterning and etching. For standard PCB production, we consistently achieve:
- การถ่ายภาพโดยตรงด้วยเลเซอร์ (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
- การขุดเจาะเลเซอร์ down to 0.1mm microvias
