Data may be delayed, corrupted (i.e., have errors) or be totally lost. Although significant delays or losses of data are rare when wireless devices such as the Sierra Wireless modem are used in a normal manner with a well-constructed network, the Sierra Wireless modem should not be used in situations where failure to transmit or receive data could result in damage of any kind to the user or any other party, including but not limited to personal injury, death, or loss of property.

1. Introduction 1.1. Overview The AirPrime Snap-in socket is available for all variants of AirPrime modules compatible with the new COMMON FLEXIBLE FORM FACTOR (CF3 ). It has been specified and tested to preserve the high level of performance and reliability of the AirPrime module used inside. As a result, the AirPrime Snap-in socket can be used for test purposes, to ease development, as well as for volume production.
2. Snap-in Socket Characteristics The Snap-in Socket is dedicated for use with any 22x23 mm HL or WP Series module from Sierra Wireless. Two variants of the Snap-in socket frame exists; one to support the HL series (66 signals on one ring) and the other to support the WP series (157 signals on 2 rings).

Mechanical Characteristics Items Conditions Specifications No defects such as cracks, Appearance scratches or blemishes.
3. Handling 3.1. Storage of the AirPrime Snap-in Socket AirPrime Snap-in socket can be stored in their original packages, for up to 1 year. Tip: For optimal results, the recommended storage temperature is +20°C ± 10 degrees. 3.2. Component Package The Snap-in Socket is a scalable QFP, 27.4x28.4 mm, pitch 0.8 mm.

Snap-in Socket. Moreover, JTAG pins are also not present on the Snap-in Socket. Sierra Wireless suggests that customers place a copper pad under the Polarity mark to avoid any risk of short circuits between this pin and the customer layout; however, there is no need to solder it.
Customer Process Guidelines SMT Assembly Process 4.2.2.1. HL Snap-in Socket The following figure shows the position of the copper pads. Figure 6. Recommended HL Series Snap-in Socket Footprint – Copper Layout Position 4115102 Rev 6.0 June 15, 2017...
Customer Process Guidelines SMT Assembly Process 4.2.2.2. WP Snap-in Socket The following figure shows the position of the copper pads. Figure 8. Recommended WP Series Snap-in Socket Footprint – Copper Layout Position 4115102 Rev 6.0 June 15, 2017...
SMT Assembly Process 4.2.3. Layout Recommendations Sierra Wireless’ layout recommendations include: A ground area under the AirPrime Snap-in Socket. This ground area should be a whole area of copper with proper ground vias to provide a good grounding system between the application and the embedded module, and improved thermal dissipation.
5. Board Mounting Guidelines 5.1. Stencil Design The recommended stencil thickness is 125 µm. The proposed stencil design is presented in Figure 12 and Figure 13 below. It is recommended to have a different stencil when mounting the Snap-in Socket and when soldering the module on its own. It is highly recommended to monitor the solder paste height, registration and proper placement during the squeegee printing.
Customer Process Guidelines Board Mounting Guidelines 5.2. SMT Process Parameters The Pick & Place area to be used for the SMT process is 3.7 mm in diameter, centered on the heat- sink. Speed: Slowest speed for the machine. Figure 14. Pick &...

Customer Process Guidelines Insertion and Removal Guidelines 2. Put the module down in the socket. Use vertical motion to insert the module. 3. Check the orientation of the cover based on the location of the Polarity mark. Polarity mark on the module should align with this Polarity mark on the module (black dot) 4.
Customer Process Guidelines Insertion and Removal Guidelines 5. Check that the cover holes are locked on the socket bumps on all sides. Cover holes 6.3. Removal Guidelines Use the specific Snap-in removal tool to dismount the cover. Figure 17. AirPrime Snap-in Socket Removal Tool To dismount the cover from the Snap-in socket, insert the Snap-in removal tool in the socket cavity, and then smoothly push the tool to pull up the cover and disengage the cover holes from the socket bumps.
