Claim Text:
1. A test method for an interposer, comprising: providing an interposer, wherein the interposer has a plurality of conductive lines therein and a plurality of connecting contacts thereon, and the plurality of connecting contacts are electrically connected to the plurality of conductive lines respectively; providing a passive transponder device, wherein the passive transponder device comprises: at least one first circuit, wherein the at least one first circuit comprises an open/short test circuit and at least one pair of connecting contacts, and the at least one pair of connecting contacts are connected to the at least one first circuit; and contacting the at least one connecting contacts in the passive transponder device respectively with at least one selected connecting contacts on the interposer to form a checking area, and conducting a short-circuit/open-circuit test for the interposer through the checking area, wherein when conducting a short-circuit test or an open-circuit test for the interposer through the checking area, a precharge signal is first provided to charge the connecting contacts of the interposer in contact with the at least one first circuit to a high voltage level, then a test result is observed to evaluate the short-circuit test or the open-circuit test for the interposer, wherein the conductive lines are originally isolated in order to disallow electrical connections in the short-circuit test, and the conductive lines are originally connected in order to allow electrical connections in the open-circuit test.
