What’s the proper soldering iron temperature for standard .031" 60/40 solder?
I recently purchased a Weller WES51 soldering iron as my first temperature controlled iron and I'm looking for recommendations on the best default temperature to use when soldering.
I'm using mainly .031 inch 60/40 solder on through-hole components.

Why do electronics have a low temperature limit?
Apart from condensation why do electronic components usually have a low temperature limit? For example my laptop says something along the lines of -10 °C to 75 °C temperature while in use.
I can understand the high temperature limit, as things will…

Minimum operating temperature - Outer Space?
I've been looking at some microcontrollers and I've seen they've got some "weird" minimum operating temperatures, like -25 degrees or -10 degrees etc. But I can't really understand why there is a minimum, a maximum I do understand because everything…

Why is the temperature range of industrial and military products so high?
From Wikipedia the common temperature range for electrical components is:
Commercial: 0 to 70 °C
Industrial: -40 to 85 °C
Military: -55 to 125 °C
I can understand the lower part (-40°C and -55°C) as these temperatures do exist in cold countries like…

Is an Arduino Uno capable of running 24/7?
I'm curious as to the reliability and durability of the Arduino Uno.
Does anybody have experience in "killing" one due to excessive use?
If so, how long did it take for the board to fail?

Who said, "all sensors are temperature sensors, but some are better than others"?
One of my favorite electrical quotes goes something like "all sensors are temperature sensors, but some are better than others". Unfortunately, I don't remember where I read this. What is the origin of the quote?

Differences between thermistors and thermocouples
As I understand it, both thermistors and thermocouples are temperature sensors. So what are the advantages/disadvantages of using one over the other to measure the temperature?
What are the specific applications for either of the sensors?

How can I measure the temperature wirelessly inside a piece of meat?
For a cooking experiment, I'd like to be able to measure the temperature inside a piece of meat while it's being cooked. Due to the mechanics of the cooking process, it's going to be difficult to use a wired temperature probe, so I was wondering if…

How do I calculate the temperature rise in a copper conductor?
If I pass a current through a copper conductor, how can I calculate how hot the conductor will get?
For example, if I have a 7.2kW load powered by 240VAC, the current will be 30A. If I transmit this power to the load via a \$2.5mm^2\$ copper…

Why do temperature-voltage curves of all thermocouple types pass through the origin?
Notice that the temperature in the graph is in °C, not even in °K.
0°C is the border between temperatures of water and ice under 1 atm pressure. Why do thermocouples give 0V voltage at a temperature of 0°C? Is there any relationship between water…

Do MOSFETs usually burn open or closed?
I was wondering if a power MOSFET fails due to overheating, will it usually burn as an open-circuit or short-circuit?
Also, does over-temp damage usually cause the gate oxide to blow through as a low resistance ( < 100 Ohms)?

Do computers speed up at higher temperatures?
At higher temperatures, will computers get faster? Evidently, one always wants cool a computer down as higher temperatures can damage core components.
However, is it an interplay between silicon, which at higher temperatures will release more…

Heating a wire with DC current; why is it hottest in the middle?
I am putting DC current through a wire to heat it. I would think the wire would heat up evenly but I have found that it is hotter the closer I get to the middle, or, respectively, colder the nearer to the clamps. Can anyone explain this?
