Homebrew PCBs

It bears mentioning for those who haven't visited the link yet, that
the instructable author uses a Phaser liquid wax printer to print wax
as etch resist directly onto flexible PCB board.

The flexible PCB is made of Kapton. According to DuPont's website:

"They have been used in field applications where the environmental
temperatures were as low as –269°C (–452°F) and as high as 400°C
(752°F). Complete data are not available at these extreme conditions,
and the majority of technical data presented in this section falls in
the 23 to 200°C (73 to 392°F) range."
