Soldering and Storage
1. Soldering
1.1 Soldering
When using a soldering iron or medium infrared ray/hot air reflow, avoid a rise in device temperature as
much as possible by observing the following conditions.
1) Using solder reflow

Reflow soldering must be performed once or twice.
The mounting should be completed with the interval from the first to the last mountings being 2 weeks.
2) Using solder flow (for lead (Pb) solder, or lead (Pb)-free solder)
・Please preheat it at 150°C between 60 and 120 seconds.
・Complete soldering within 10 seconds below 260°C. Each pin may be heated at most once.
3) Using a soldering iron
Complete soldering within 10 seconds below 260°C, or within 3 seconds at 350°C. Each pin may
be heated at most once.
