When finish circuit design

I am new in Arduino world, and also in electronic at all.

I am almost finish my project. And I want to start regular exploatation of it.

But as long as I know that I can sold/weld all my components, I am not sure how to make solid/stable connecctions with Arduino UNO.

The sockets in Arduino UNO are quite loose. I mean inserted cables can be easily disconnected if somebodo throw it or during journey.

That’s why I want to ask about best/proven procedures to ensure stable connestions in Arduino UNO.

For any help great thanks in advance.

Best regards.
