ACCURATE AND HIGH-SPEED MEASUREMENT ON SMT BOARDS

Comprehensive Test Coverage
Phase detection measurement and Guarding function ensures precise meas-urements in parallel circuits, 4-wire Kelvin measurement for low-value resis-tances by eliminating the effect of probe contact resistance, etc… Taking advan-tage of the latest measuring technologies, the APT-9411 series measures a wide range of components at high speed and accurately.

Accurate And Flexible Contact
Probe access is programmable based on board topology. Probing speed is slowed down just before contacting the test lands to minimize stress and possible damage to test lands. You can also safely test sensitive SMT boards.

Vision System
The APT-9411 series incorporates a high performance image processing unit that ensures reliable and accurate automatic optical test. Accordingly the tester inspects missing, misalignment, or reversed components that are normally not measured during electrical test.

IC OPEN TEST SYSTEM
IC Open test system is a powerful option to detect unsoldered IC leads in the bus circuits that are hard to detect by measuring internal protection diodes. A unique sensing probe technology is introduced to detect unsoldered IC leads on QFPs and SOPs, as well as unconnected solder balls of most BGAs.
