Chip appearance defect detection content:

1. Scratches, chipping and foreign matter: these defects may affect the electrical characteristics of the chip, or even lead to product failure.

2. Pin size, mutilation, and deflection: the quality of pins directly affects the connection reliability of circuit products.

3. Flatness, uneven spacing: these problems may lead to problems in the packaging and use of the chip.

4. Coating quality: peeling or scuffing of the coating can affect the reliability and performance of the chip.

Types and features of FA lenses:

Industrial Lens

① High resolution: Provides clear, detailed images to meet the accuracy requirements of industrial applications.

② High Contrast: Enhances the contrast of the image, which helps to better analyse and detect the features of the target object.

③ High Optical Performance: High-quality optical materials and design are used to ensure colour accuracy and minimise distortion in images.

④ Durability and Stability: Designed for use in industrial environments with high durability and stability.

Zoom Lens

① Variable magnification: the magnification can be flexibly adjusted within a certain range to meet the imaging needs of different observation distances and object sizes.

② Wide range of applications: suitable for electronic component inspection, mechanical parts processing, life sciences and materials science and other fields.

③ Motorised variable magnification: widely used in automated inspection systems, can be remotely controlled and conveniently integrated into complex industrial automation systems.

Telecentric Lens

① Low aberration: Significantly reduces magnification variations due to angle of view, maintaining consistency and accuracy of object size measurement.

② High Telecentricity: Ensures that light entering the lens is incident on the photographic element almost parallel to the optical axis.

③ High depth of field: maintains clear image quality at different distances.

④ Coaxial Illumination: Enables shadow-free illumination and improves the accuracy of the machine vision system.

The best lens choice for chip appearance defect detection:

The optimal lens selection for chip appearance defect detection should be decided based on specific inspection needs and scenarios, taking into account the high resolution of industrial lenses, the flexibility of zoom lenses, and the measurement accuracy of telecentric lenses.

1、High resolution industrial lens: suitable for high-precision detection of chip surface defects in the scene, such as scratches, chipping and foreign objects.

2、Variable-magnification lens: When it is necessary to observe the details of chip pins, coating quality, etc., the variable-magnification lens can provide more flexible magnification options to meet different inspection needs.

3、Telescopic Lens: In the scene where high precision measurement and reduction of image distortion are required, the telescopic lens is the best choice. It is suitable for the chip pin size, flatness, spacing and other parameters for accurate measurement of the scene.
