[0002] After the preparation of CIS (CMOS imagesensor) chips, they need to be tested and evaluated before they can enter normal use. The testing of CIS chips usually requires the use of different types of probe cards.
[0003] When testing the existing CIS probe card, it is necessary to adjust the installation position and height of the lens to ensure that the light generated by the light source is projected onto the photosensitive area of the chip under test after being refracted through the lens, and the surface and optical center are consistent. In order to ensure the accuracy of the above projection, the chip usually needs to be placed on a carrier and then the worker manually fine-tunes the chip position.
