RECOMMENDED LOCATION FOR PICK AND PLACE

The flat top surface of the large inductor (topside of the board) provides a versatile and convenient way of picking up the

module (see Figure 56). A 6-7mm outside diameter nozzle from a conventional SMD machine is recommended to attain

maximum vacuum pick-up. Nozzle travel and rotation speed should be controlled to prevent this off-centered picked-up

module from falling off the nozzle. The use of vision recognition systems for placement accuracy will be very helpful.

REFLOW NOTES / RECOMMENDATIONS

1. Refer to the recommended Reflow Profile per

Figure 57. Profile parameters exceeding the

recommended maximums may result to

permanent damage to the module.

2. The module is recommended for topside

reflow process to the host card. For other

orientations, contact factory.

3. In the event that the module needs to be

desoldered from the host card, some pins

may be detached from the module.

MODULE MARKINGS / LABELS

Marking shall be permanent and legible.

Please refer to Figure 58 for the module

marking/ label detail.
