Advantest E6978-66442 Printed Circuit Board Assembly

Advantest E6978-66442 Printed Circuit Board Assembly is a populated PCBA used as a key test-interface module in Advantest's 93K/93000 semiconductor test system family. The E6978-66442 sits within the E6978-6642x series, where nearby part numbers include E6978-66422 (passive control board) and E6978-66424 (active control board), as well as front-plane and related boards like E6978-66492 that form the broader test-interface assembly. In production and service settings, such PCBA modules connect the tester’s control and signal paths to the device-under-test sockets, enabling reliable communication and timed sequencing required for high-density device testing. Advantest markets these boards as interchangeable components within its Interconnect Solutions ecosystem, designed to be replaced or upgraded as test configurations evolve. The broader corporate context shows Advantest’s approach to test interfaces through partners like R&D Altanova, a supplier of consumable test-interface boards and interconnects, which underscores the role of PCBA modules like the E6978-66442 in enabling end-to-end test solutions. Typically used by equipment service technicians and test engineers working with 93K/V93000 systems, this PCB assembly helps maintain probe-card and socket-level connectivity essential for repeatable test results.
