Hi all:
I have an application where I'm using a -40°C rated circuit board I'm designing in a -55°C environment. Finding parts that work down to -55°C is very difficult, expensive and frustratingly inconsistent.
I am looking for a thin heater pad that I can use to warm up my circuit board up to -40°C or higher. This would be under processor control or thermal relay or something equivalent via PWM control. The critical part is the PCB mountable servo amp that's rated only at -40°C and the manufacturer is adamant not to use it below that temperature, hence the desired to keep its temperature within spec.
My board space requirements are extremely tight. The enclosure for my ciruit board is only 6.0" W x 6.0" L by 1.0" H.
Can anyone help
Thanks,
David
