Probe card of using information code to identify and method thereof

Abstract

The invention relates to the automatic identification field and especially relates to a probe card of using an information code to identify and a method thereof. Identification of the probe card is ensured, consequences of conditions that an existing RFID is easy to drop and lose and so on are avoided, simultaneously, cost needed for purchasing the RFID is saved, an expense of a probe card portion needed by a WAT test is reduced and errors caused by the probe card during processes of manufacturer maintenance and the like are decreased.

Description

technical field [0001] The invention relates to an automatic identification technology, in particular to a probe card and method for identification by using an information code. Background technique [0002] Radio frequency identification, RFID (Radio Frequency Identification) technology, also known as radio frequency identification, is a communication technology that can identify specific targets through radio signals and read and write related data without the need for mechanical or optical contact between the identification system and specific targets. The difference in resistance value of the resistor also determines that it can be applied to industrial identification. [0003] The existing technology uses radio frequency identification technology (RFID) to identify the WAT test probe card, and there will be several problems: the RFID is not firmly bonded, the glue is aging, and the manufacturer is easy to drop or lose the RFID when PMing the probe card. Not only does i...

Problems solved by technology

[0003] The existing technology uses radio frequency identification technology (RFID) to identify the WAT test probe card, and there will be several problems: the RFID is not firmly bonded, the glue is aging, and the manufacturer is easy to drop or lose the RFID when PMing the probe card. Not only does it add a lot of extra workload, but it is also likely to cause wrong RFID sticking between different probe cards, which brings trouble to the test; the probe card is easy to drop during the test, which may cause machine downtime, and the consequences cannot be solved. Estimate; if the RFID installation position is not accurate, the machine will not be able to recognize the probe card; if the RFID is installed improperly, the probe card will damage the sensitive components inside the machine during the test; the physical and consumable nature of RFID will require regular purchases, which will also a small fee

However, when the probe card is identified by resistance, there will be problems such as limited identification information and high risk of reading errors.
