How many solder cycles does Arria10 support?

Hi, Sometimes it happens, that PCBs need to be reworked. Is there any specification about the supported number of soldering cycles an Arria10 FPGA supports? Where can I find that documented? Be...

Hi MS,

Just would like to clarify if you are referring to the reflow peak temperature of Arria 10. If yes, you may refer to AN353 document, Table 2:

https://www.altera.com/en_US/pdfs/literature/an/an353.pdf

For Arria10 which is lead free part, the peak reflow temperature could be referred to Table 4 of AN353.

Time within 5C of peak Tp of lead free part is 30 seconds while the number of reflow cycles = 3.

The max reflow time for our device is 3 times. The 3 time reflow adopted by JEDEC/IPC 020-D is based on the assumption that most devices on the PCB will see 3 temperature excursion.

· 1st reflow

· 2nd reflow (double sided board)

· 1 extraction (or rework)

They expect the device to be still functioning with 3 times reflow.

Hope this clarify.

Regards,

Aim
