FA1240-61 / FA1241-61
FA1240-63

Hioki PCB and substrate inspection equipment leverages our core competency in high precision component testing. The FA1240 series is a 4-arm populated board inspection tool that delivers multi-functional testing in as fast as 0.025 sec./step.

The Hioki FA1240-61 is a specific model within the FA1240 series of flying probe testers, primarily used for high-speed, high-precision electrical inspection of populated (assembled) printed circuit boards (PCBs) without requiring a custom test fixture for each board type

• Large Testing Area: The model -61 has a generous testing area of 510 x 460 mm, making it suitable for a wide range of large board applications.
• High-Speed Testing: It can perform tests at a rapid pace, up to 0.025 seconds per measurement step, which aids in high throughput on production lines.
• Measurement Versatility: It can measure resistance (from 400 µΩ to 40 MΩ), capacitance (from 1 pF to 400 mF), inductance (from 1 µH to 100 H), and Zener diode voltage.
• Defect Detection: The device uses proprietary technology to reliably detect subtle defects like “lead float” (where an IC pin has poor contact but appears correct visually) and “pseudo-contact” conditions, which are hard to find with standard visual inspection.
• Automated Functions: It features automatic alignment and simple visual test functions (using a CCD camera), as well as automatic calculation of probe interference based on component height data, simplifying program creation.

Applications

• Populated PCB Testing: Its main purpose is to perform in-circuit testing on boards after components have been mounted, verifying that all parts are correctly placed and functioning within specifications.
• Quality Assurance: It is an essential tool in electronics manufacturing for detecting various defects, ensuring solder quality, and preventing faulty boards from reaching the market.
• Fixture-less Inspection: As a flying probe system, it uses four independently moving probes to contact test points dynamically. This eliminates the need for expensive, dedicated “bed of nails” fixtures, saving time and cost, especially for prototyping or low-to-medium volume production runs.
• Battery Module Inspection: The FA1240 series is also used for testing the quality of welds in electric vehicle (EV) battery modules, visualizing weld defects based on highly accurate resistance measurements.
