Abstract: A probe card provides signal paths between integrated circuit (IC) tester channels and probes accessing input and output pads of ICs to be tested. When a single tester channel is to access multiple (N) IC pads, the probe card provides a branching path linking the channel to each of the N IC input pads. Each branch of the test signal distribution path includes a resistor for isolating the IC input pad accessed via that branch from all other branches of the path so that a fault on that IC pad does not substantially affect the voltage of signals appearing on any other IC pad. When a single tester channel is to monitor output signals produced at N IC pads, the resistance in each branch of the signal path linking the pads of the tester channel is uniquely sized to that the voltage of the input signal supplied to the tester channel is a function of the combination of logic states of the signals produced at the N IC pads.

Abstract: A nosepiece for use with a riveter for installing a blind bolt. The nosepiece has an active area which is annular and effectively matched to the dimensions of the locking collar of the blind bolt. No tapered surface interferes with the sleeve during installation of the blind bolt. Instead, the active area includes a protrusion which intersects a support surface generally at a ninety degree angle. Providing a minimum or no transition fillet radius from the active area to the support area allows for a minimum length of the active area, providing maximum reinforcement to the active area. It also concentrates the operating stresses in a known area, dispersing them from the critical, working surface of the active area, providing an expected failure mode.

Abstract: In slack removal processing for removing slack generated on a wafer sheet by heating blow, a wafer feeding plate is positioned at a height position between a first height position and a second height position. This makes it possible to decrease a gap between an upper end portion of an expanding ring and a lower face of the wafer sheet and allows efficient and uniform processing. Moreover, setting the height position so as to avoid the contact between the wafer sheet and the upper end portion of the expanding ring at least when the slack removal processing is completed reliably prevents shrinking operation of the wafer sheet from being disturbed by the contact between the wafer sheet and the upper end portion.
