6.3 Recommendation reflow profile

1. We strongly recommend that this module should be designed to mount
on top side of motherboard with main chip together which process the
final reflow.

2. The maximum frequency of this module to pass reflow process should
be no more than twice, including repair operation , otherwise it may
cause side effect to the performance.

3. Below is the recommend reflow profile referred to Main chip MT3318.
