Teradyne Inc. announced an advanced vectorless test tool for detecting open pins on components and connectors assembled onto PCBs. FrameScan FX 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. With FrameScan FX, users can detect open pins more accurately and with greater repeatability, said the company.

FrameScan FX is a complete hardware and software suite that can extend a user's measurement capabilities. It solves test issues associated with the many smaller device packages and connector technologies used on today's board designs. FrameScan FX 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.
