  • Detection device and manufacturing method thereof
    Patent number: 11237189
    Abstract: A detection device includes: a metal body having a plurality of main vias, a plurality of main through holes with insulators formed on the hole walls of the main vias, and a plurality of connecting elements disposed in the main through holes. Therefore, when testing a chip with I/O pins of high density with the detection device, the connecting elements contact the insulator only, without contacting the hole walls of the main vias, and the problem of short circuits can be avoided. A method of forming a detection device is also provided.
    Type: Grant
