EVA100 plus relay matrix · beyond 5,000 channels
PSTA20K Ultra-High-Channel Socket Tester
A socket holds no die, so the only way to find the one bad contact is to put current through every one of them. PSTA20K uses an Advantest EVA100 to supply 256 test channels, then fans them out through a relay matrix and a socket-specific motherboard to thousands or tens of thousands of contacts, clearing open, short, leakage and per-pin contact resistance before a processor is ever installed. It is a derivative of the PCT5801 probe card test platform and shares the same channel-expansion and measurement architecture.
Category visual for socket test equipment. The actual motherboard, fixture and pin map are designed per socket sample.

CONFIGURATION
Configuration and acceptance
System configuration, optional items and acceptance conditions are summarized below.
Architecture and specification
EVA100 front end, relay matrix fan-out, PMU and measurement ranges are taken from the Probing socket tester product documentation Rev 1.7 (2024-11-15).
Channel scale
16,384 is the architectural ceiling of the relay matrix. The product is positioned for beyond 5,000 channels, and the delivered configuration follows the socket pin map and motherboard.
Test time
Nominal test times are quoted per 5,000 channels and exclude load/unload and temperature settling. Actual takt is confirmed by measurement once the target pin map and limits are fixed.
