3D VISION INSPECTION

Overview

Fancort is an expert developer and integrator of 3D vision inspection systems utilizing the latest sensor and software technologies. Our engineers have experience developing 3D solutions for defect detection and dimensional verification down to 4-micron resolution. Our software engineers can develop seamlessly integrated turnkey solutions utilizing the latest in machine learning and direct data extraction from today’s leading sensor manufacturers. It’s this “best of both worlds” approach of combining leading software and sensor technologies that result in unrivaled solutions for the most demanding applications. An excellent example of our work is the Veri-Spec 3D SMT Form Inspection System. This system was developed as the world’s most accurate SMT dimensional inspection system. It is a parametrized (scalable) dimensional inspection system that verifies inputs from our SmartFlex.

Parameter (Scalable) Inspection Solutions

Today’s 3D vision inspection sensors can produce astounding resolution and huge data sets. It’s what you do with this data that counts most. Sensors alone lack the ability to teach, scale, or set up multiple array solutions easily. On the other hand, machine learning software is gaining ground and becoming easier to use with each passing year. However, a successful machine learning or AI software application needs to be carefully designed to achieve the desired goal or, in some cases, may be overkill. This is where Fancort can help your team bridge the gap by developing a parameterized or scalable turnkey solution. These solutions can be characterized as being tailored to the specific application. The result is a fast and easy-to-use solution with fewer compromises.

Customizable Experience: Choose what data to view and save.

User Interface

User interface can display simplified “GO/NO-GO” indications or be set to display advanced measurement viewing and visualizations.

Data Logging

All process data can be logged locally and/or remotely to a SQL server. Logging options can be chosen to include only the data relevant to the customer.
- MEASUREMENT VALUES
- PROCESS SETTINGS AND VALUES
- 3D POINT CLOUD DATA
- PART NUMBERS AND CUSTOM DATA

Process Control

Viewable control charts for tracking process stability under the influence of a range of factors.

High-Precision Line Scanner / Laser Scanner

High-Precision Line Scanner / Laser Scanner

The scanner has a minimum resolution of 4 μm and a repeatability of 0.4 μm (height) / 0.5 μm (width).

Lead Processing Inspection Systems

Each lead is individually processed to reduce noise issues on highly reflective surfaces. Noise is eliminated without compromising scan data.

3D laser scanner vision system settings are also adjustable and can be saved for each lead material and package.

Specs. and Options

Measurement Options

Each lead is automatically processed and measured individually.

Profile Angles

Measure the lead angles relative to the body.

Toe Angle of 5.079 degrees

J Height of 0.9634 mm

Profile Widths

Measure the lead widths.

Lead width of 0.1925mm

Profile Bend Radii

Measure the radius of each bend.

Bend radius of 0.0118”

Advanced Lead Measurements

System utilizes computation of finite difference of lead profiles to find bends. Finding bends allows the dynamic application of best-fit circles to each bend for radius measurement, and allows for partial lead-length measurements.

Lead Profile, 1st Derivative, 2nd Derivative

XY Angle

Measure individual lead’s XY angle relative to the body.

The top right shows the intersection angle is 88.6/91.39 degrees.
