Abstract
A test probe card structure includes a probe card and a connection circuit common plate. The probe card includes a probe substrate, A test circuit board is disposed between the probe substrate and the connection circuit common plate, The test circuit board has a lest circuit connection section attached to and electrically connected with a common circuit adaptation section of the connection circuit common plate. A circuit extension section is formed around the connection circuit common plate, which is all-channel electrically connectable between a tester and the teat circuit connection section. The connection circuit common plate serves to provide an all-channel test circuit convergence connection ability for the test circuit board so as to greatly minify the size of the test circuit board and lower the manufacturing cost of the probe card.
