ERNI Electronics Further Expands Successful SMC Family
SMC Board-to-Board Adapters with 68 and 80 Pins

ERNI Electronics continues to expand its popular and well-established 1.27mm SMC connector family with new adapters. Due to the high contact density and small space required, SMC connectors offer a maximum of design flexibility. Today, ERNI introduces SMC Board-to-Board adapters with 68 and 80 pins.

The adapters enable an increased flexibility by expanding the possible mezzanine board-to-board distances to fulfill 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 40mm – wipe length included – are possible. In addition, this solution enables a secure soldering process by using the low-profile female connector and pick & place technology. With this, component height is no longer an issue for the SMT assembly line. Furthermore, the adapter can be attached during the end-assembly process so the daughter boards can be stacked close to each other without being damaged.

By introducing the new parts, ERNI now offers a range of adapters with 12, 26, 50, 68 and 80 pins. The adapters with 1.27mm 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. Hence 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. The operating temperature ranges from -55 °C to + 125 °C.
