1. INTRODUCTION
This specification covers the requirements for application of the 152 position QSFP-DD 112 Stacked pc
board connector. The connector consists of a housing with right-angle surface-mount contacts having
spacing on 0.8mm centerlines. The connector features a paddle card entry slot that accepts 1.00±0.10
thick integrated circuit card housed in a plug body with alignment posts for stability of placement and
needle-eye pins to secure the connector on the pc board. The connector is mounted on host pc board
and is used on coordination with an EMI cage attached to the same pc board. The pins and cage provide
proper alignment to the connector.
The connector is supplied in packaging trays for manual or robotic machine placement. Basic terms and
features of this product are provided in Figure 1.

This manual provides information on various flux types and characteristics with the commercial designation and flux removal procedures. A checklist is included in the manual as a guide for information on soldering problems. 2.5.
- Page 3 NOTE Call the number at the bottom of page 1 for suitability of other pc board materials. B. Tolerance Maximum allowable bow of the board shall be 0.08 over the length of the connector. The coplanarity of the pc board circuit pads must be 0.03. C.
- Page 4 3.6. Mounting Alignment of needle-eyes is important when mounting connector to PC board. Entry clearance between leading edge of needle-eyes and holes can be as low as .4 mm. Begin by gently lowering connector to board, allowing leading edges of needle-eyes to guide themselves into the holes. Once the object is lowered enough to contact thicker cross-section of needle, pressure should be added to push pins through board to secure components together.

- Page 6 F. Cleaning After soldering, removal of fluxes, residues, and activators is necessary. Consult with the supplier of the solder and flux for recommended cleaning solvents. Cleaners must be free of dissolved flux and other contaminants. It is recommended cleaning the pc board on its edge. If using aqueous cleaner, standard equipment such as a soak-tank or an automatic in-line machine should be used.
- Page 7 4. QUALIFICATION QSFP_DD pc board connectors are Recognized by Underwriters Laboratories Inc. (UL) in File E28476. 5. TOOLING No tooling is required for manual placement of the connectors onto the pc board. For automatic machine placement, the robotic equipment must have a true position accuracy tolerance sufficient to properly locate the connector.
