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. he 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 SiRF chipSet.

Note: 1.Please reference Pb-Free assembly

2. tp reference table 4-2 blue mark
