I am making a led matrix. I am using a plastic foam board but i have one concern. I am worried that i might melt the plastic foam board. i am using an arduino nano and supplying it with 5v 4 amps. this is where i got the board https://www.ebay.com/itm/6mm-1-4-SINTRA-PVC-FOAM-BOARD-PLASTIC-SHEETS-YOU-PICK-SIZE-COLOR/281822001847?hash=item419de67ab7:m:mLjZodgCsPEFueRomtJognA
Do you have a question?
All LEDs produce heat that must be dissipated into the air somehow. Compute the current used by each LED times the voltage and that is the power(heat) that must be taken care of. Leaded LEDs use the leads the conduct the heat away. SMT LEDs use the leads and the circuit board traces.
Big LEDs use a heat sink of some type to dissipate the heat. What are you using?

thank you i am a beginner in electronics and arduino. I'm trying to replicate the matrix as in the youtube link in the bottom. I bought the same LED strips. I will have 100 LED on the board and the wires connecting them on the bottom face of the board. The board used in the youtube project is wood. I'm trying to use the foam plastic board as in the ebay link I provided.
will the board stand the tempreture generated? Do I need to cool it somehow or use wood instead. I will be using 5 v 4 amp power supply.
Thank you in advance.
Make your own 10x10 LED Matrix - YouTube. i am using WS2812B led strip.

The LEDs are SMD devices soldered to individual circuit boards which will dissipate the heat. Based on what I see, the mounting can be almost any way because the LEDs and boards are all inside a plastic tube.
I did find this warning, which I will paste here, in case you did not find it.
Warning: The WS2812B seems to be more sensitive than the TM1804 on our original LED strips. We recommend taking several precautions to protect it:
Connect a capacitor of at least 100 μF between the ground and power lines on the power input.
Avoiding making or changing connections while the circuit is powered.
Minimize the length of the wires connecting your microcontroller to the LED strip.
Follow generally good engineering practices, such as taking precautions against electrostatic discharge (ESD).
Consider adding a 100 Ω to 500 Ω resistor between your microcontroller’s data output and the LED strip to reduce the noise on that line.
