SZ-X1 Offline SMT AOI Equipment Specification

I. Product Introduction

1. AOI Working Principle

Adopt modern optical technology and digital camera technology to capture real-time images of workpieces. Images are analyzed and processed via computer and dedicated software to automatically generate inspection results.

2. Functions of AOI

•        Effective inspection rate of AOI: Over 99% (manual inspection rate: approx. 70%)

•        Labor reduction: 2–4 workers per production line with high inspection efficiency

•        Built-in SPC function to accurately count process defects for effective quality control

•        Far higher stability than manual inspection; significantly lower overall long-term operation cost

•        Enhance corporate strength and overall market competitiveness

3. Core Advantages

(1) Supported Inspection Items

•        Post-wave soldering DIP inspection: Excessive solder, insufficient solder, solder voids, short circuits, unexposed pins, etc.

•        SMT inspection: Missing components, offset components, wrong components, reversed polarity, damaged parts, contamination, insufficient solder, excessive solder, short circuits, cold solder joints, etc.

Defect types covered: Wrong capacitor/resistor, cold solder, missing parts, short circuit, offset, empty solder, terminal short circuit, unexposed pins, solder voids, etc.
