Jumper Wire Nightmare
image
A routing miscommunication resulted in a significant problem. The circuit traces for connectors on the left side of a circuit board were supposed to route to the connectors on the right side. Unfortunately the opposite was true. Do to time considerations re-manufacture was not viable option. There were a few options considered.

image
Several multilayer backplanes were mistakenly manufactured with missing plating for 24 holes on each board. The top and bottom side pads were in place, but the holes had no plating thus the inner layers were not connected. After consultation it was decided that the best rework approach would involve machining down to the inner layers and connecting copper ribbon to complete the connection on the ...

Cooling Without Electricity
image
Today, it's estimated that worldwide electricity costs total roughly $2.5 trillion a year and that cooling systems consume 15% of that electricity. With experts forecasting demand for cooling to grow ten-fold by 2050, that means electricity expenditure for cooling alone could rise to nearly $4 trillion per year. Fortunately, there appears to an extremely clever and cost-effective way of doing just ...
