The eXpert tester is the latest in a long line of Exatron Logic Testers. eXpert combines for the first time: high pin count conventional vector test with Exatron's signature analysis test. For the first time: fast test with an accurate AC/DC test. For the first time: program and test with just one insertion. For the first time: built-in true fault grading for both conventional test vectors and automatically generated eXpert vectors.

The primary concern of all test programmers is "UPH," units (tested) per hour. eXpert is fast, very fast. Test times of under 500 milliseconds are typical for very complex devices, to under 10 milliseconds for simple devices. eXpert uses state of the art fast A/D and D/A SMD test circuitry. The internal signal path for all 160 I/O pin drivers is under 4 inches. Exatron's Particle Interconnect (P.I.) socket technology allows the number of connections from the tester's pin drivers to the DUT, even in a handler environment, to be as few as just 2 connections, counting the DUT itself. This permits eXpert to perform very accurate AC tests without the need for traditional "offsets". Add a hardware based, not PC based, fast PLD/PROM programmer and you have a test system that delivers REAL production.

eXpert is very compact, measuring 15" round and 11.5" deep. Add a keyboard and a monitor and the tester is complete. No additional computer is required. A Pentium PC is built into eXpert. This internal PC is equipped with both a 3 1/2" floppy drive and a hard disk drive. eXpert software is machine language based and operates under DOS for maximum speed. Installation of Windows NT/95 is not required, but can be installed for network applications.

eXpert is well suited for many applications. Digital logic tests from the simplest of TTL small pin count logic, to high pin count complex FPGA's can all be easily tested. The tester's small size and fast test times makes it ideal for wafer probe/test.

On the manufacturing test floor, when direct docked to a test handler, eXpert provides a zero footprint. In incoming inspection applications, eXpert's "self learning" software makes test set up nearly automatic.

Auto Handler Contactor PCB
The Auto Handler Contactor PCB connects the DUT to the eXpert. High performance Particle Interconnect (P.I.) sockets for surface mount devices with lead pitches as small as 0.4mm are offered. The Exatron socket technology allows one test socket for both hand test and automated test. This saves time and money. Conventional test sockets, i.e. Yamaichi, Johnstech, Textool, Ney, and others, are available as well.

Manual Test Socket
The Manual Test Socket connects the actual DUT to the DUT Adapter PCB. Particle Interconnect test sockets, as well as conventional test sockets, i.e. Yamaichi, Johnstech, Textool, Ney, and others are available. The number of test sockets required depends on your application.

Test & Mark Applications
Using Exatron's proprietary SmartMark technology, eXpert can operate either laser or label marking machines to uniquely mark every device with pass/fail, lot/date codes, quality ratings, etc. When used with an Exatron marking machine, no additional PC is required.
