QFN to QFN Adapters
QFN to QFN adapters provide an interface between QFN device sockets and QFN plug footprints used in emulator and production test environments.
Overview
QFN to QFN emulation adapters provide an electrical interface between a QFN device socket and a QFN plug footprint used in emulator or fixture environments.
The top interface consists of a QFN socket matched to the specified pin count for device insertion during emulation. The bottom interface presents a QFN plug designed to mate with standard QFN emulator or production sockets.
Selection is based on QFN pin count and the corresponding QFN plug configuration. Adapters may be wired 1:1 or with defined device-specific routing depending on part number.
Top Interface: QFN socket (device under test)
Bottom Interface: QFN plug footprint
Routing: 1:1 or device-specific mapping
Mechanical dimensions and electrical routing details are defined at the individual product level.
QFN interface geometry conforms to standard QFN footprint dimensions corresponding to the specified pin count and package body size.
The plug interface is compatible with common production and emulator QFN sockets used in laboratory and fixture environments.
Substrate material is rigid FR-4 with plated-through vias. Pad geometry and copper weight are controlled to maintain dimensional stability and signal integrity.
Overall height, insertion depth, and body dimensions vary by part number and are specified at the product level.
QFN to QFN adapters are available with defined routing schemes based on device and socket requirements.
Routing options may include 1:1 pin mapping between QFN pads, device-specific remapping, and defined skips, tied pads, or required shorts where specified by the device.
Routing configuration is defined at the product level. Refer to the individual part page for exact signal mapping and electrical definition.

Not Finding What You Need?
Some QFN to QFN applications require specific pin mapping, socket geometry, or device-defined routing. If the adapter required for your device is not listed, Adapt-Plus can assist with custom adapter solutions for emulator and fixture environments.
Custom adapters are available for development, validation, and production test requirements.
