20140015560 | INTERFACE BOARD OF A TESTING HEAD FOR A TEST EQUIPMENT OF ELECTRONIC DEVICES AND CORRESPONDING PROBE HEAD - An interface board of a testing head for a test equipment of electronic devices is described. The testing head includes a plurality of contact probes, each contact probe having at least one contact tip suitable to abut against contact pads of a device to be tested, as well as a contact element for the connection with a board of the test equipment. Suitably, the interface board comprises a substrate and at least one redirecting die housed on a first surface of that substrate and a plurality of contact pins projecting from a second surface of that substrate opposed to the first surface. The redirecting die includes at least one semiconductor substrate whereon at least a first plurality of contact pads is realized, suitable to contact a contact element of a contact probe of the testing head, the contact pins being suitable to contact the board. | 01-16-2014 |
20130049782 | METHOD FOR CLEANING A CONTACT PAD OF A MICROSTRUCTURE AND CORRESPONDING CANTILEVER CONTACT PROBE AND PROBE TESTING HEAD - A method for cleaning a contact pad of a microstructure or device to be tested when it is in electric contact with a measure apparatus, being obtained by electrically contacting a flexible probe with said contact pad. The method includes mechanically engaging a free end of the flexible probe in a manner that sticks the free end in the pad; and laterally flexing, by means of a tip charge, the flexible probe in a manner that keeps the free end stuck in the pad, so as to locally dig into a covering layer of the pad and realize a localized crushing thereof. | 02-28-2013 |
20120280703 | TESTING HEAD FOR A TEST EQUIPMENT OF ELECTRONIC DEVICES - A testing head for a test equipment of electronic devices comprises a plurality of contact probes inserted into guiding holes made in at least one upper guide and in a lower guide, separate from one another by an air zone, the contact probes comprising at least one enlarged portion suitable for preventing the escape of such probes from the guiding holes. Conveniently, the enlarged portions of the contact probes adjacent according to a direction of distribution of contact pads of an integrated device to be tested have respective larger sides orthogonal to one another. | 11-08-2012 |
20120280702 | TESTING HEAD FOR A TEST EQUIPMENT OF ELECTRONIC DEVICES - A testing head for a test equipment of electronic devices of the type includes a plurality of contact probes inserted into guide holes which are realized in at least an upper guide and a lower guide separated one another by an air zone. Each of such contact probes include at least a probe body having a substantially rectangular section and a projecting arm from the probe body which ends with a probe tip for contacting one of a plurality of contact pads of a device to be tested. The projecting arm projects outside the probe body so as to have a lug with respect to both faces of the probe body which converge in an edge in order to define a probe tip offset and external with respect to the probe body. | 11-08-2012 |
