All the heat that comes off the machine comes from powering the machine. The more heat that comes off it, the more energy that went into the machine. When the machine is cold there is no heat energy leaving the machine. Therefore complete cooldown

What do you think about optimal setup for 8-hour working shift and 16-hour standby time. What is the most energy efficient setup for standby time? Complete cooldown or maintaining temperature in solder pot?

Background on activation energy for diffusion can be found: * Materials textbooks * College lectures posted on the web. Use 'google' or someother search tool. As a guideline, the higher the activation energy, the harder is is for diffusion to occur

Thermal mass is the ability of a material to absorb heat energy. * A lot of heat energy is required to change the temperature of high density areas, like a ground plane. They are therefore said to have high thermal mass. * Light weight areas, such as

"In your example, you are comparing "Energy used to heat the solder and keep it warm" versus "Energy used to keep the solder warm" and fully discount the fact that the machine was ever turned off." Track and field fans refer to this as the "Bob Cost

We have different Solder mask 'gloss' and 'satin' the gloss has a surface energy =40 dynes. The test evidence to date is strong correlation between surface energy, mask type, HASS failure

http://michaelbluejay.com/electricity/cooling.html this page has it right about minimizing AC energy use. With the wave, look at two machines. One you turn off, the other you let idle. The one that is turned off is using no power. The other one is

the temperature difference between solder and room temperature, So if you let the solder cool down, you need less energy then holding it on temperature + heating a bit up. 2. If you let the solder get to solid, you don't have oxidation. 3. If you l
