Abstract
Vectorless test techniques are attractive methods to quickly and inexpensively identify and diagnose common process related defects on manufacturers printed wiring boards. Junction Xpress is a new AC method developed to locate open and marginal solder connections without the use of digital vectors or overclamp style capacitive probes. Measuring response harmonics rather than simply the fundamental AC response reduces the tendency of false accepts of open connections
