FrameScan FX is an advanced vectorless test tool for detecting open pins on components and connectors assembled onto PCBs. Uses an enhanced in-circuit capacitive coupling technique that tests for open pins by applying an AC signal to an un-powered PCB node and measuring the voltage coupled to a plate positioned in close proximity to the component or connector being tested. Users can reportedly detect open pins more accurately and with greater repeatability.
 
The complete hardware and software suite can extend measurement capabilities. Solves test issues associated with smaller device packages and connector technologies.  Hardware improvements include a new low-noise op amp that increases the front-end gain of the active probe to minimize the effects of noise upon other stages of the measurement circuit.  Software improvements include an automatic Precision Mode that increases the number of measurement samples for low measurement signals.
