Because there’s no profile of soldering in the datasheet. I think it will be ok
to refer to the solder reflow profile of ADIS16251. But it seems there’s some
problems when refering this soldering profile like the following emails
described. Have you met this phenomena before and do we have more suggestions
on ADIS16255 soldering?
The ADIS16255 (obsolete) and ADIS16265 support Pb-free solder-reflow assembly,
per JEDEC J-STD-020. This assumes MSL5a moisture exposure management, in
accordance with JEDEC J-STD-033. According to JEDEC J-STD-020, the peak
temperature for the ADIS16265 (related to device volume) is +250C. What type
of solder are you using? SAC305 solder typically melts at a temperature
between 217 and 222C.
