Hi there.
I am working on a project which will be essentially a commercial product. Its an Li-Po 3.7V 5000mAH Battery Powered IoT Wireless Device consist of an ARM CPU Module and some other necessary circuits (Like Power Regulator, Battery charging, USB, LCD etc).
Below is the ARM CPU Module I like to use:
Now due to some Connector placement requirement I had to place the CPU Module at Bottom Side of the PCB and underneath it the Li-Po Battery will be there. So Basically the Parts stack will be like this inside the Plastic Enclosure.
I found the CPU Module generates heat when operating. I can not say what amount of heat it generates but if I slight touch the Processor Chip with finger tip ... its very very hot.
My ques is ... is it good idea to place the Parts like the picture above? Here I am afraid about the heat heat dissipation. Any idea in this regard? Please note I can not use too bulky Heat-Sink as my device need to be compact in size. May be I can allow 2mm gap between battery and CPU Module. Is there any kind of thin material which I can put between Battery and CPU which can help here? Also is there any risk if the Li-Po gets hot due to heat of CPU?
Thanks in advance.
Regards.
