Standard mechanical requirements for System Level Test Boards (SLTBs) can accelerate our SLT customers’ hardware development process, which is repeated with each new DUT type. The SLTB development process typically includes integration across multiple, third-party companies to create the unique PCBAs and IC sockets while still interfacing with Teradyne SLT test equipment. This presentation will describe the requirements and why they matter. It will also reference a recent Teradyne internal project that tested this very process on a commercially available DUT. The project included development of a Teradyne-made SLTB PCBA, and contract work for the unique IC socket and support mechanics for use on a Halos SLT tester. The SLTB IC socket development process was indicated with Yamaichi using the standard mechanical requirement for SLTB, and developed in-house by Teradyne’s Device Interface Solutions team. The success of this project and creation of standard SLTB requirements demonstrates Teradyne’s commitment to pioneering SLT test development.
