Automated Optical Inspection-AOI

Automated Optical Inspection-AOI, high-speed high-precision optical image detection system, using machine vision technology as testing method can improve shortcomings of labor inspection method.

AOI machine is an industrial system with optical instruments made surface condition of finished products and then to computer image processing techniques to filter foreign objects or patterns detected abnormalities and other defects.

AOI technology combined with optical sensing systems, signal processing systems and analysis software, currently used in factory production and qualitytesting to screen for machine tool and screw component of defective parts and metal surface abnormal state of the optical detection device.

1. Detection accuracy: + / – 1 Pixel
2. CCD Camera
3. Detection speed depends on size

Thin Film Coating Measuring Instrument

X-ray fluorescence is the most precise measurement method, especially for small-diameter ../parts/, or dual coatings. X-ray fluorescence can analysis thickness of precious metals.

Sample types: plating, coating, film solution (element content of the bath)
Simultaneous determination of five layers / 15 elements / coexisting elements
Materials and alloying elements analysis
Spectrum than four samples simultaneously display
Detectable range of elements: Ti (22) ~ U (92)

LongCloud as professional manufacturer of metal surface treatment can benefit from this advanced technology by measuring coating thickness and metal composition.
It is high accuracy, good stability, powerful statistical functions, wide measurement range and NIST certification standard sheet.

The data can also be easily converted to a tabular report via the E-Form barcode scanner or through a computer using the RS232 interface and cable.

  • RoHS Test
  • Heavy metal content detection

The XRF testing can be used as a screening checkpoint at every stage of production to reduce the risk of misuse of non-RoHS materials. With a switchable dots detection function, the solder point and other details of the detection has a higher focusing ability. XRF analyzer optional point detection function, the detection range can be as small as 3mm. Element analyzers are used in a wide range of applications, in addition to materials testing, environmental regulations (RoHS). LongCloud qualified testing engineers using the XRF analyzer, engineers must obtain training course of radioactive material or can-occur free radiation equipment operator.
