High Density Power Supply Cabinet

ATE Industry's First Advantest 256 Channel Powersupply Solution

Efficient testing with enough tester resources

Today, cost efficiency is more important than ever. Many manufacturers are working on maximizing multi-site testing. Often maximization cannot be achieved efficiently because of limited tester resources. The Integrated Device Power Supplies for the Advantest T5365 (IDPS65) is meant as an external extension to increase the number of DPS’s (Device DUT Power Supplies) of the T5365 tester.

DPS system

The system consists of a 19-inch mainframe, containing the system power supplies, control interface and DPS board modules.  The SE-DPS connects directly to the HIFIX Advantest Handler using dedicated cables. The tester communicates with the SE-IDPS65 unit through a control interface and is linked into the tester bus chain. The SE-IDPS65 has control capabilities for current clamps, current measurement, voltage references, calibration factors, limit value setting and relay switching. All settings can be controlled from within the normal tester environment. The system comes with its own calibration and diagnostics software, to ensure proper functionality and accuracy. 

DPS Module

A SE-DPS is scalable with 12 channel modules. Each channel on the board has its own current measurement circuit and range selection. Current clamping is programmable for the 12 channels together. Each board will also contain it’s own reference voltage for the 112 channels.

Customizable

Because of the modular concept of SE-IDPS65 the DPS system can be adapted to virtually any customer specification.

FV-range: Forced Voltage range.

• All channels have a range of 0.6 - 2.5 V
• Voltage setting resolution: 2mV.
• Accuracy: +/- 5mV.
• Ripple noise: 5mVpp.
• Slew rate: 50uS/V (at current measurement range = 2A).

FI-max: Maximum Forced Current

• All channels are designed for FI-max = 2A
• FI-max for PPS2 and PPS4 together = 2A
