SN74LVC1G17: How many times can this part be reflowed?

Hi Miyano,

See here for our reflow guidelines: MSL Ratings and Reflow Profiles (Rev. A)

As long as you stay within the appropriate reflow classification, the device is rated for up to 3 reflows in accordance with JEDEC J-STD-020. See page 13 here: QFN and SON PCB Attachment (Rev. C) (ti.com)

Best,

Malcolm
