One last comment from me today.....
I was told by a service agent for FLIR that the cameras that followed the PM Series were not as well built or mechanically robust. I consider the E2 to be proof of this statement. It really is a pretty poor design inside.
Ignoring the 'bodge' wires, which I might add have been executed very well, it is the whole feel of the case and PCB retention mechanisms. They all feel very much like a prototype rather than a production unit. The main PCB is secured to one half of the case using quality screws and plastic embedded brass ferrules. The microbolometer sub-assembly that sits vertically behind it is quite frankly an appalling piece of engineering. Truly a joke. The plastic chassis is supposed to sandwich a heat-sink and thermal pads between two PCB's (Main and sub)....it doesn't do this well and the PCB's pop out of their tiny retaining clips. The thermal pads are not able to do their job as they are no longer in contact with the IC's that they are supposed to help cool.
The sub-assembly has not a single screw on it. The heat-sink is used as the mounting for the sub assembly and a single aluminium arm extends down to the cameras tripod mounting where it is retained by a single screw. It is fair to say that apart from this single mounting point and the connector that joins the assembly to the main PCB, this thing is floating

Crazy when you realise that the heat-sink cools the main processor in the camera ! The heat-sink should be screwed down onto the main PCB to ensure good thermal transfer.
More poor design is to be found in the display section. The LCD panel is placed into a carrier and little plastic clips are glued on either side of it to roughly retain it. The whole LCD panel is floating with no proper impact absorption material present. It is eventually held in place by fingering around the clear plastic screen ... read on, it gets better (or should that be worse?)...... the LCD display carrier also contains the rubber keypad. The LCD carrier and keypad are clipped onto the display PCB. The display PCB is free to move up and down in the clips by at least 2mm

That is to say, if you try to press a rubber keypad button, the PCB moves down and away from the panel by around 2mm ! So how is the display PCB kept in place ?...... not a retaining screw to be seen. The display PCB mates with a large connector on the top edge of the main PCB. The display case retaining screws sandwich the display board between the display case and the main PCB edge connector. Great design ..... NOT !
What can I say ? It is certainly not one of FLIR's finest designs, and considering how expensive they were when new, I would go as far as to say it is shoddy workmanship by the mechanical design team.
