Tool/software:

Hi team,

Today I introduced TMP114 to my customer and highlighted our chip can place under processor easily.

But customer asked me one question " how to do PCBA (PCB + Assembly)"??

Does customer mount our chip and Processor together in the PCB? The reflow soldering process is then carried out.

Or should they mount our chip first and reflow then mount processor next?

Thanks

Hi Paul,

When we tested this, it was mounted with two reflow passes. It's up to the assembly vendor to figure out a flow that works for them. Under chip mounting like this may not always be practical.

thanks,

Ren,

According to your comment, it seems this kind of design is not real practical because it is depended on assembly vendor's ability. Am I right?

For us, we will suggest separate two reflow process. Actually it is not convenient for customer in manufacture side.

Please correct me if I misunderstand your comment.

Thanks

Under chip mounting is a novel idea. It's not the only use or benefit of TMP114.
