Question about Soldering of LIS2DH12

I am a new user of ST’s LIS2DH12. I am confused about the sentence 'Leave “Pin 1 Indicator� unconnected during soldering'. It was in chapter 4.1 Soldering information in datasheet of LIS2DH12. What this sentence mean? And why does Pin1 need disconnect?

And how can I achieve Leaving

“

Pin 1 Indicator

�

unconnected during soldering

?

I agree the datasheet is confusing, but don't worry. For your information some devices have 'pin 1 indicator' on the bottom close to pin 1. I could be small dot or triangle, which looks like very small pad. The sentence says you should not solder this indicator. The pin 1 of course needs to be connected.

It seem it is not the case of LIS2DH12, beacuse pin one is indicated by cut corner.
