What it is
The Teradyne ETS-88 is a production board test system designed for precision power and analog testing of printed circuit boards.[1]
How it works
General reference — not yet source-verifiedThe ETS-88 is an automated test system that typically interfaces with a printed circuit board assembly through a bed-of-nails fixture, making electrical contact with test points on the board.
The system contains multiple instrument modules to apply stimulus and measure responses, enabling in-circuit testing of analog and power components such as resistors, capacitors, diodes, and voltage regulators.
Where it fits in the process flow
General reference — not yet source-verifiedThe ETS-88 is typically used in the production board test stage of electronics manufacturing, after solder reflow and visual inspection, and before final functional test or system integration.
The tester is employed to verify correct component placement, solder joint integrity, and proper circuit operation on assembled printed circuit board assemblies.
Applications
The ETS-88 is used for production board test of printed circuit board assemblies in industries such as automotive, aerospace, and industrial electronics.[1]

Frequently asked questions
What types of devices can be tested with this class of machine?General reference — not yet source-verified
Machines of this class are designed to test a broad variety of semiconductor devices, including digital, analog, mixed-signal, and power management ICs. The specific device types depend on the instrument configuration and the test head used.
How does the test system interface with a wafer prober?General reference — not yet source-verified
The test system connects to a wafer prober through a mechanical interface that aligns the probe card with the wafer. The test head provides electrical connections for all probes, and the prober steps the wafer under computer control while the tester applies signals and collects measurements from each die site.
What test capabilities does this class of equipment typically support?General reference — not yet source-verified
Typical capabilities include DC parametric measurement (voltage, current, resistance), functional logic testing, frequency and timing measurement, analog waveform generation and capture, and built-in self-test (BIST) support. Many systems also offer parallel test to increase throughput.
How is the test program developed for such a system?General reference — not yet source-verified
Test programs are created using the system's proprietary software environment, often with a graphical user interface for pattern generation, test flow definition, and limit setting. The program is compiled and loaded onto the tester, then debugged using simulation and dry-run modes before production use.
What are common maintenance considerations for this class of machine?General reference — not yet source-verified
Regular maintenance includes calibration of power supplies and measurement instruments, cleaning of probe card or socket interfaces, and periodic software updates. Downtime is minimized through preventive maintenance schedules and use of spare parts such as Pogo pins, cables, and cooling fans.
