SCORPION FLS980Dxi Flying Probe Tester
Board test capabilities that go way beyond what other flying probes are capable of.
Why are dozens of electronics manufacturers in industries ranging from aerospace to automotive and health sciences to semiconductors, depending on the Acculogic Flying Probe Test Platform for their production testing?
Because they can always ship products with a quality they’re proud of. Circuit board test is getting more complicated. In-circuit tests often cost too much, take too long, and cover too little. But production quality needs to be verified without causing production delays, without cost overruns, and without hassles.
Production Test Challenges
Tight quality control measures and time-to-market pressures are compelling manufacturing companies to choose effective yet lean test and quality control strategies. Flying probe testers require no test fixtures, have few restrictions on board access, and can test boards with a virtually unlimited number of nets.
They also allow developers to complete test programs in a short time. With the SCORPION FLS980Dxi Flying Probe Tester, manufacturers can stay ahead of their competition and economically ensure product quality by catching defects before their customers do.
Flying probe and in-circuit testers (ICT) are used to test printed circuit board assemblies (PCBAs) to ensure quality and functionality.
However, they have some differences in operation, flexibility, and cost-effectiveness.
A flying probe tester is a fixtureless testing tool that utilizes multiple movable test probes to contact specific points on the PCB. It measures the electrical properties of components and checks for shorts, opens, or incorrect component values.
In-circuit testers use a custom test fixture, known as a "bed of nails," to make contact with test points on the PCB. In-circuit testers are generally more suitable for medium to large-scale production.
Flying Probe Testers - key points
- ➡️No need for custom test fixtures: Flying probe testers do not require test fixtures, making them suitable for low to medium-volume production runs and ideal for prototyping and rapid design changes.
- ➡️Flexibility: They can easily adapt to different PCB designs and test complex, dense boards.
- ➡️Shorter setup time: generating test programs is usually quick, and Test programs can be updated to accommodate design changes, enabling faster testing turnaround and reducing production delays.
- ➡️Lower operating cost: elimination of fixture costs reduces NRE costs, making flying probe testing more cost-effective for prototypes and small to medium production runs.
In-Circuit Testers - key points
- ➡️Custom test fixtures: ICT uses custom test fixtures, often called "bed of nails," to contact test points on a circuit assembly.
- ➡️Medium to high-volume production: Electronic manufacturers typically use ICT for medium to high-volume production.
- ➡️High test speed: In-circuit testers can perform tests faster than flying probe testers, as they can access multiple test points simultaneously, making them suitable for high-volume production.
- ➡️Higher initial cost/NRE: The custom test fixtures required for ICT can be expensive, especially for low-volume production or prototypes.
- ➡️Longer test development time: Designing and manufacturing custom test fixtures can lead to more prolonged setup times.
- ➡️Less flexibility: Any changes in the PCB design may require updates to the test fixture, increasing test preparation time and cost. This makes ICT less adaptable to frequent design changes than flying probe testers.
The FLS 980 Catches Defects Before It’s Too Late
The Flexibility of the FLS 980Dxi
The Scorpion Flying Probe Tester is an effective testing solution that can be used throughout a circuit board's lifecycle. During the prototype testing phase, flying probe testers can quickly and accurately test small production runs, enabling engineers to identify and correct any issues before proceeding with full-scale production. In production testing, flying probe testers can provide high-speed and accurate testing for medium to high-volume production runs. And in repair depot testing, flying probe testers can help diagnose issues with boards that have failed in the field, minimizing downtime and reducing repair costs.

Boundary Scan/JTAG Test
Boundary Scan is very good at testing for IC shorts on nets that have boundary scan drivers, and it is also very good at detecting IC opens on boundary scan nets that have at least one boundary scan driver and one receiver. If memory devices are connected to scannable parts, they will also have boundary scan coverage.
Using a combination of digital boundary scan stimulus and analog flying probe voltage measurement can be used to test the functionality of certain types of circuits, such as A/D and D/A converters and voltage references.
Power-up, Functional & RF Testing
Several sources can be used to power up a UUT inside the FLS980 tester. The ability to power up and flexibly control the UUT allows for functional block testing of onboard power generation circuits, operational amplifier circuits, and simple voltage tests. The UUT power supplies have standard current and voltage monitoring capabilities, which can be used to limit or sample board draws under different load conditions. This flexibility in powering the UUT allows for more extensive test coverage and can help ensure that the device or system being tested is functioning properly and meets the necessary specifications.
