Sinowon Vision Measuring Machine Applications in PCB Manufacturing Process

Precision Geometric Dimension Measurement Solutions for OMM & PCB Quality Control

In PCB (Printed Circuit Board) manufacturing processes - including material cutting, drilling, circuit patterning, plating, soldermask application, legend printing, and final shaping - Sinowon's video measuring system serves as an essential OMM (Optical Measurement Machine) solution for comprehensive quality control. Key applications include:

1. Raw Material Inspection
   Measure copper-clad laminate thickness and flatness at pre-production stage. [Show copper-clad laminate image]
2. Drilling Process Control
   Accurately verify hole diameter and positional accuracy, resolving multilayer PCB alignment issues. [Show drilled substrate image]
3. Circuit Pattern Verification
   Ensure trace width, thickness, and spacing compliance for stable signal transmission. [Show PCB panel image]

4. Final Product Validation
   Complete dimensional inspection of formed PCBs to confirm machining precision matches design specs. [Show finished PCB image]
