Test adapter meets OSM standard

The OSM (Open Standard Module) standard for directly solderable and scalable embedded computer modules describes four different-sized, space-saving and flexible solder-on modules that can be assembled, soldered and tested completely automatically. A test adapter from Yamaichi Electronics can be used to ensure these modules are contacted safely and reliably. They can be used in a manual as well as automatic test process.

Yamaichi Electronics developed the adapter platform for the open standard modules as a modular system with easy handling and robustness are the key features. Its spring contacts have been selected from the company’s own production and there is a matching cover. The module contacts are precise and reliable over thousands of cycles, confirmed the company.

The test adapter is available in four sizes to accommodate module sizes 0, S, M and L. It is simply attached and easily screwed onto a carrier board. e.g., a base or evaluation board, which provides the corresponding contact pads according to the standardised pin layout. Care has been taken to minimise the space required by each of the four test adapters to provide maximum space for your application.

For secure mounting on the base or evaluation board, a stiffener is counter-screwed to the underside of the carrier board. This supports the PCB and ensures outstanding contact reliability.

The modular design consists of a base socket, the cavity for module mounting, a lid and a module-specific insert (pusher). Double spring-loaded contacts establish the connection between the OSM and the base or evaluation board.

Optionally, the cavity for holding the OSM standard also contains the corresponding tolerances, in case the OSM is fitted with components on the reverse side.

To support your safe, reliable, and on-time test and production start-up, an early integration into the development process of the OSM is recommended to fix mechanical degrees of freedom according to the module specification.

The OSM tester adapter will be displayed by Yamaichi Electronics at Embedded World (24 to 16 March) in Nuremberg, Germany on its stand in Hall 1-341.
