SF-MATE   Short Finder Module All Data Aquisition Boards

Short Finder test instrument adds ICT capabilities
SF-MATE
The SF-MATE (or Short-Finder), is a unique test instrument that adds ICT capability to Functional Test equipment. Rather than spending thousands of dollars to test all nodes on a PCB, the SF-MATE limits the number of checks to those defined as critical test points. For example, during a typical assembly process, a PCB inadvertently receives shorts in the lower section.
By verifying specific test points are "short free" (prior to applying power to the PCB), the SF-MATE can prevent damage to the DUT, adjoining test equipment and possible injury to the test Operator. The SF-MATE has 8 input channels that are connected to a special Ohm meter circuit. After a channel is selected, a constant current is supplied to the device-under-test and a voltage is measured that is proportional to the resistance. The Ohm meter limits the current source to 1mA, and the open-circuit voltage is just 200mV (which is less than the nominal turn-on voltage for most PN junctions). When the input exceeds a certain level, the SF-MATE outputs a digital bit that indicates a short .
