BCM20732S and BCM20737S data sheet state max. reflow temp = 245°C

but process needs 250°C.

Can Broadcom confirm 250°C reflow temperature is possible?

Hello Michael:

For the 32S and 37S Devices;

  1. Normal RoHS Pb-free reflow temp is 245°C
  2. 20732S product suggest spec is 245°C.
  3. 260°C has been tested by our packaging house, but has never gone through a formal QA process, so we can only guarantee 245°C

Thanks,

JT

I will need to ask around to see if I can find someone that can answer this question.

The reflow guidance within the datasheet is typically what we gaurantee.

Are these devices specified according to IPC/JEDEC J-STD 020D-01 Moisture/Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices ?


Then they should sustain max. temp of 260°

Other App-notes (e.g. PACKAGING-AN902-R) are according to this standard
 

Please verify if BCM20732S and BCM20737S are specified to be processed according to
IPC/JEDEC J-STD 020D
