Product Description:

For many years, cleaning experts have used the world's mature SITA fluorescence measurement technology, including handheld devices, to control various shapes of parts or specific components to continuously and quickly measure their cleanliness online. SITA's new product Fluoscan 3D is a universal, non-contact device for controlling cleanliness levels.

The use of organic substances such as oil, grease, and surfactants that can excite fluorescence under ultraviolet irradiation can easily and reliably detect organic pollutants on parts. The system adopts a three-axis positioning device to automatically scan the surface of the part according to a preset path, with measurement points up to 50 times per second. The test results are displayed in RFU (relative fluorescence unit) values, and the larger the measurement value, the greater the pollution.

Measurement system features:

-High density automatic measurement

-Fast and reproducible surface inspection and evaluation

-Appropriate individual measurement sequence

-Combination of single measurement and surface scanning

-Stable design

-Intuitive software integrated into the system

-Testing and adjustment based on SITA verification standards

-The measured values are comparable to SITA's portable and online cleanliness meters

-Flexible use for new measurement tasks

measuring principle

During the manufacturing process, some typical pollutants such as oil, grease, or surfactants will emit fluorescence when exposed to ultraviolet radiation.

The intensity of fluorescent radiation increases with the thickness of the pollution layer.

An integrated UV-LED light source excites fluorescence, and a photodiode measures the intensity of the generated fluorescence radiation.

application area

Automated testing before welding die cast aluminum

Release agents are used in the manufacturing process of casting parts. In the subsequent process, such as the bonding of the sealing groove, the residual release agent will lead to insufficient adhesion of the bonding joint.

Check the cleanliness of the sealing groove through fluorescence measurement to ensure the quality of the joint.

Inspection of Printed Circuit Boards

In order to meet the high-quality requirements of bonding and welding processes, circuit boards must be free of any organic contamination. Control and ensure high-quality standards through a scanning cleanliness meter.

Early detection of deficiencies and defects can prevent and eliminate expensive system failure costs.

software

Composed of two independent components

-During the measurement process, the individual parts are tested in different locations, and the measurements of different parts of the parts are summarized into one measurement

-Measurement Data Viewer (displaying measurement results)

An independent result viewer can display and evaluate measurement results on various computer devices, as well as output data to Excel
