To remain on pace with the semiconductor technology advances, Integrated circuit (IC) test solutions must offer greater functionality while maintaining a low cost of test. One of the fast-growing emerging markets for semiconductor chips these days is in mobile-charging applications such as the e-mobility and rapid charger market.
Test equipment supplier Advantest Corporation is advancing the testing of power and analog ICs used in the emerging automotive, industrial and consumer mobile-charging applications such as the e-mobility and rapid charger market. The company announced that it has extended the performance of its scalable semiconductor test platform V93000 with a 250W floating power VI source (FVI16) for testing live power and analog ICs.
“Customers can use the new FVI16 to extend the capabilities of their existing V93000 Smart Scale systems to the higher voltages, increased channel count and power demands for high-site-count IC testing while maintaining a low cost of test”, according to the announcement.
“With the FVI16, this versatile test platform is equipped for testing semiconductors for a wider range of power-management devices, from airbags and ABS (anti-lock braking system) controllers to USB-C chargers and cordless power tools.”, the company said.
By supplying 250 watts of high-pulse power and up to 40 watts of DC power, the new source helps to provide sufficient power testing latest generation devices while conducting stable and repeatable measurements.
The system features a digital feedback loop design that the company says provides the best source, measurement accuracy and analog/power performance on the market, compared to competitors’ systems that operate with a traditional analog feedback. Digital feedback technology offers several unique features including spike-free “smart connections” with constant Kelvin monitoring for reliable and highly precise measurements. User-controllable slew rate and bandwidth settings allow fast settling times adapted to the respective load conditions.
The FVI16 unit is also said to feature the industry’s highest instrument-channel density, enabling small system configurations that fit into Advantest’s A-Class test head and therefore lowers cost of test. Sixteen channels with four-quadrant operation allow for source ganging of up to 155 amps per card on high-current tests. For high-voltage testing, source stacking of up to +180 volts per card within a floating range of + 200 volts can be achieved.
The FVI16 has an integrated fast current clamp to protect the loadboard hardware, probe card pins and DUT sockets in case a damaged device creates a short circuit.
The company notes that its FVI16 floating power VI source is already in use at several customer sites, and has generated multiple orders from leading automotive customers in Europe and Japan. Advantest is offering flexible licensing arrangements that allow customers to select the best fit for their specific needs.
