The press-fit termination means it installs without solder: the compliant pins cold-form into the plated through-hole, which is standard for backplane assemblies where rework access is limited and solder-joint reliability under thermal cycling is critical. The EMI shielding is built into the cage structure to contain the radiated emissions from the high-speed differential pairs running at 25 or 28 Gbps per lane. ## Press-Fit Assembly and Board Layout The press-fit tail drives the board-side process: the cage is pressed into the PCB using a pneumatic or arbor press with a back-up tool supporting the opposite side. No wave solder or reflow step is needed on the cage itself, though the host board may still run through reflow for other components. The heat sink is integral to the cage; it draws thermal energy from the module's top surface through a thermal interface pad (not included). Airflow direction over the fins should be considered in the chassis thermal design.","metaTitle":"TE Connectivity 2227249-3 ZQSFP+ Cage","metaDescription":"TE 2227249-3 ZQSFP+ cage assembly, ganged 1x4 with integrated heat sink.

The ZQSFP+ interface is designed to support 28 Gbps NRZ per lane (QSFP28) and 56 Gbps PAM4 per lane (QSFP56) when used with the appropriate transceiver module. The cage itself does not set the data rate — that is determined by the module and the host board's signal integrity. The press-fit termination and EMI shielding are specified to maintain the signal integrity envelope needed for those speeds."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/2227249-3","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/te-connectivity-amp-connectors/2227249-3 when reusing this data.
