Is it time for mil-spec in plants?

Nice article Joe. Quite enlightening. Is the potential solutioin to this mil-spec parts? Certainly ruggedized parts can better withstand high temperature even if they cost a bit more.

I'm confused. In the example shown, there are three (3) dimentions for the panel area (2ftx4ftx1ft), but this should yield a volume (ft3), not ft2, as shown in the example. Assuming a rectangular prism with six (6) sides, there are two sides with 8ft2 each,two with 4ft2 each, and two with 2ft2 each, for a total surface area of 28ft2. Also, which side is the bottom surface that you are ignoring? Did I miss something? Please help.

Panel is 4' tall 2' wide and 1' deep

4*2 = 8 square feet surface area front

4*2 = 8 square feet surface area back

1*4 = 4 square feet surface left side

1*4 = 4 square feet surface lright side

1*2 = 2 square feet surface are top side

TOTAL surface area = 26 square feet

O.K., Thanks, I get it now. The bottom of the panel is one of the small (2ft2) sides. BTW, the superscript for ft2 was dropped during editing of the original article, so the areas are shown as ft instead of ft2.

EXAIR does have high temperature cabinet coolers. They are good for environments of 200 degrees F. They are of stainless steel construction so they are corrosion resistanct as well

Practically all electronic devices today contain metals that may be coming from conflict-ravaged African countries. And political pressures will increasingly influence how these minerals are sourced and used in products.
Conformal coatings present themselves as space-saving alternatives to enclosures for protecting the circuit boards of automotive electronics. They can also provide electrical insulation.
Design for manufacturing (DFM) in mold production means that mold designers evaluate the manufacturability of their molds in the early stage of mold development by collecting all relevant information and applying it to their designs. They also have to consider many other factors, including flow balance, structural stress, and assembly tolerance, in order to ensure successful molding production.
Some adhesives provide strong structural bonds but take hours to fixture and attain handling strength. The technologies that offer the fastest cure do not bear loads or withstand stresses. A new class of adhesives aims to make both stick.
