Overview
QFN to QFN adapters provide an electrical interface between compatible QFN package configurations used in development, validation, and socketed test applications.
The top interface consists of a QFN socket or QFN device footprint matched to the specified package configuration and pin count. The bottom interface presents a compatible QFN plug footprint designed to mate with standard QFN socket systems and interface hardware.
Selection is based on QFN pin count, package body size, pitch, and required interface configuration. Adapters may use direct 1:1 routing or defined device-specific signal mapping depending on the application and part number.
Top Interface: QFN socket or QFN device footprint
Bottom Interface: QFN plug footprint
Routing: 1:1 or device-specific mapping
Mechanical dimensions, electrical routing, and compatibility specifications are defined at the individual product level. Refer to specific product pages for detailed configuration information.
These adapters are part of the IC Adapters product family.

Not Finding What You Need?
Some QFN to QFN applications require device-specific pin mapping, custom socket geometry, or application-defined routing configurations. If the required adapter configuration is not listed, Adapt-Plus can assist with custom adapter solutions for development, validation, and socketed test environments.
Custom adapter configurations are available for interface conversion, engineering development, fixture integration, and specialized test system requirements.
