Manufacturers in high-end semiconductor and display module production are continuously seeking ways to improve product reliability while minimizing errors during quality control. This has created a constant need for more accurate inspection methods.

The Adimec S-25A30 and S-25A70 cameras have established themselves as successful products in the semiconductor inspection and metrology sector, providing high-resolution (global shutter), high-image-quality cameras at competitive prices. These models utilize the ON Semiconductor Vita 25k image sensor, which has become a benchmark for quality machine vision cameras.

To meet new requirements for inspecting and calibrating display modules like OLEDs in mobile phones, several improvements are necessary:

  • Higher resolution
  • Better inspection throughput (speed)
  • Ability to detect small contrast variations
  • High sensitivity for measurements conducted under low-light conditions

The S-65A35 and S-65A70 models address these needs by offering increased precision through their 65-megapixel resolution combined with high speed. They incorporate the latest advancements in image quality and improved light sensitivity, largely thanks to the new GPixel-TPSco 3.2 mm Global Shutter sensor (GMAX3265) and Adimec’s camera design expertise.

The Gpixel GMAX3265 is a cutting-edge sensor featuring a 9344 x 7000 pixel array on a compact 37.4mm diagonal, ideal for high-resolution requirements in demanding high-speed applications. This new generation sensor provides low read noise and an excellent wide dynamic range due to its true correlated double sampling (CDS) global shutter technology. Optional removable cover glass is available to address reflection issues.

Key Specifications of the S-65A Series

High-Resolution Imaging Capabilities

  • 9344 x 7000-pixel format
  • 37.4 mm sensor diagonal
    • The S-65A35 CXP 1.1 variant supports up to 35 fps
    • The S-65A70 CXP 2.0 variant achieves a maximum of 70 fps
  • Available in color (S-65A35 only) and monochrome options
  • Utilizes global shutter technology for motion-free imaging

Pixel Size Characteristics (3.2 μm)

  • The compact 2×3.2 μm pixel size accommodates 65 Megapixels while using a physically smaller sensor than the previous Vita 25k model.
  • Despite its reduced physical dimensions, this pixel size offers sufficient full well capacity and angular sensitivity for quality imaging.

Compatibility with Previous Models

Smooth Transition from S-25 Series

The new S-65A series shares several compatibility advantages:

  • The sensor is physically smaller than the Vita 25K but provides similar optical performance while offering more than double the pixel count.
  • It maintains the same form factor as previous Adimec S-25 cameras for simplified integration.

Interface and Speed Considerations

The S-65A35 uses the same CXP 1.1 interface standard as its predecessor, ensuring compatibility with existing systems. For users requiring maximum performance (70 fps) with the S-65A70 model, an upgrade to the faster CXP 2.0 interface is necessary.

These advanced features make the S-65 camera series a significant improvement for real-time metrology and inspection applications in semiconductor manufacturing and display calibration. Adimec has minimized development costs and system impacts when transitioning from their successful S-25 models to these newer platforms.
