Laird SSD45N Hardware Integration Guide, version 0.01 Recommend footprint (TOP view) Solder Stencil Opening for Pads (56 signal pads): 1:1 to 1:0.9 (dependent on solder type) Solder Stencil Opening for Thermal Pads (9 “window pane” pads): 1:0.5 to 1:0.75 (dependent on solder type) Note: The ground vias that are in the thermal pad (6x6 pattern of 12 mil holes) are open; they are not tented by the solder mask on the bottom side.
Laird SSD45N Hardware Integration Guide, version 0.01 Rework is technically challenging due to parts on the SIP reflowing at the same temperature needed for rework. The SDC-SSD45N cannot be lifted by the shield during rework. As such, removal of part for rework is not recommended. Reflow without removal has been successfully used to clear shorts found during x-ray inspection. Reflow: The SDC-SSD45N is RoHS compliant and as such is sensitive to heat.
Laird SSD45N Hardware Integration Guide, version 0.01 RF LAYOUT DESIGN GUIDELINES The following is a list of RF layout design guidelines and recommendation when installing a Laird radio into your device. Do not run antenna cables directly above or directly below the radio. Do not place any parts or run any high speed digital lines below the radio.
Laird SSD45N Hardware Integration Guide, version 0.01 Need to place enough ground via under the SSD45NBT. Important: The landing pad of the U.FL connector will cause induced capacitor when the distance to the reference ground plan is less than 10 mils. This will decrease the RF performance on 5GHz. It is must to remove the ground plan in the inner layer. Be sure to make the reference ground continuous.
