Solder msop-8 max temperature ?

rompelstilchen · Apr 9, 2020

Hello,

with such small packages, I was wondering what was the max temp to solder these?

the datasheet says the max temp these chips can handle is 150° but melting tin needs at least 250°

thanks for your advices on this

150° maxiumum temperature isn't specific to these packages, you'll find similar specs for most semiconductor devices, IC and discretes. They are nevertheless designed for lead-free solder process with necessary temperatures, you find reflow temperature profiles in datasheets and application notes.

A special problem of very thin packages (smaller than MSOP) is their maximum "floor live" after been taken out of the sealed dry bag. Before reflow soldering, they need baking. Read about MSL https://en.m.wikipedia.org/wiki/Moisture_sensitivity_level

I dont have any reflow aparatus, just my soldering iron

there is no MSL nor reflow temperature info in the datasheet

Hi,

there is no MSL nor reflow temperature info in the datasheet

The manufacturer gives an application note with soldering recommendations.
(As every manufacturer should do)

But you know the package is not designed for iron soldering, thus you may refer to the reflow informations.

This MSOP package has no exposed pad and can be well soldered with fine soldering iron tip.
