  • Publication number: 20220170961
    Abstract: A probe card and a manufacturing method of a probe card are provided. The probe card includes a probe head, first and second substrates, a first elastic component, and a first adhesive member. The second substrate is disposed between the probe head and the first substrate, and is disposed on the first substrate. The second substrate faces the first substrate and includes second contacts. The second contacts are electrically connected to first contacts of the first substrate. The first elastic component is disposed between the first substrate and the second substrate, and disposed at an outer side of the second contacts. The first adhesive member is disposed on the first substrate, annularly arranged on the side surface of the second substrate, and disposed at an outer side of the first elastic component.

  • Patent number: 7554477
    Abstract: An amplifier array circuit is provided. An amplifier array includes a main amplifier array comprising a plurality of first amplifiers and a plurality of reference voltages, wherein the first amplifier is coupled to an input signal and the reference voltage corresponding to the first amplifier. A first reversed reference voltage amplifier array is located on one side of the main amplifier array and has a plurality of second amplifiers coupled to the input signal and the reference voltages, respectively. A second reversed reference voltage amplifier array is located on the other side of the main amplifier array and has a plurality of third amplifiers coupled to the input signal and the reference voltages respectively. The averaging network is coupled to a first output terminal and a second output terminal of the first, second and third amplifiers.
