Hello,
In my project, my microcontroller may have to operating in +70 celcius C.Will this temperature influence the board behave? Any electronic elements on the board could be have a problem with the high tempreature?
please any idea will be valuable for me!

That is why they publish such information in data sheets. Try reading the data sheet for the components you will be using and de rate for temperature where necessary.

As someone said you have to check the spec sheets. Typical operating range is to 85C. But I don't know about uC's. You have to look at the derating of any power components on the board. At higher ambient temperature they get too hot if asked to disipate too much power.

What "microcontroller"?
All these things have specifications. Find the datasheet and/or specifications for whatever microcontroller you have.
Anything else is just guessing.
Yes, the temperature will influence how the board behaves vs. room temperature.
Yes, electronic components can have problems at high temperatures.
If you're designing the board, pay attention to the temperature range of each part, and design the circuits to the data sheets' worst-case specifications. Also pay attention to the power consumed by each part, and calculate the heat rise so that you know the parts are operating within spec. Then test.
If you're buying a board, try to get a candidate board that's rated for the temperature, and before you're 100% committed to using it, try to test it at temperature.

it's hot, but not too hot for most things.
start downloading datasheets.

Look for automotive grade parts. They regularly have to deal with ambient temperatures above that.
