SMC board-to-board adapters

8 July 2009 Interconnection

Erni Electronics has expanded its popular 1,27 mm SMC connector family with new board-to-board adapters featuring 68 and 80 pins. The adapters enable increased flexibility by expanding the possible mezzanine board-to-board distances to fulfil the needs of various modern applications.

In combination with the related low-profile female connector (unmated stacking height of 6,25 mm) board-to-board distances from 20 to 40 mm – wipe length included – are possible. In addition, this solution enables a secure soldering process by using the low-profile female connector and pick-and-place technology. The adapter can be attached during the end-assembly process so the daughter boards can be stacked close to each other without being damaged.

Erni’s SMC connector range now features adapters with 12, 26, 50, 68 and 80 pins. The adapters with 1,27 mm pitch have male contacts on both component sides. One side provides a robust snap-fit interlocking feature which works together with the standard low-profile female connector mentioned above. In this way, the adapter is steadily linked with the low-profile female connector to the base board while maintenance or service purposes are performed on the mezzanine board side. For cost-effective processing the adapters are delivered in an antistatic tray packaging. Operating temperature ranges from -55°C to


+125°C.
