A self-marking chip bad point testing device

The invention discloses a self-marking chip bad pixel testing device, which belongs to the field of chip detection technology. This solution uses an ultrasonic detection ring to detect bad pixels on the chip, and at the same time lays a color-changing marking layer made of two thermochromic particles with different color-changing temperatures on the chip. When a bad pixel is detected, a light-emitting module is used to generate a high-temperature light beam to irradiate the color-changing marking layer to mark the damaged part. When the damaged position is deep, the position is continuously irradiated to cause the color-changing marking layer to produce a secondary color change, so that staff can quickly understand the specific damaged position and reasonably judge whether it is worth repairing. Ferromagnetic fluid is used in combination with a magnetic film to be attached to the inner wall of a reflective cavity, which improves the concentration of the light beam and enables the thermochromic particles to change color quickly. When the temperature inside the reflective chamber is too high, the ferromagnetic fluid loses its magnetism and cooperates with the light-dissipating heat dissipation chamber to absorb a large amount of light, thereby reducing the temperature of the reflective chamber and extending the service life of the device.
