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

·Temperature profile example of lead (Pb) solder

·Temperature profile example of using lead (Pb)-free solder

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.
