Thermoelectric quartz crystal micro-balance - Thermal vacuum
bakeoutThere are, generally, three conventional treatment methods used to clean, scour or fully-react silicone substrates, respectively, and these include solvent extraction, thermal vacuum
bakeout and enhanced silicone curing processes
Fortunately, if undercured mask creates wave-soldering issues, frequently they can be remedied by simply completing the cure cycle - either in a
bakeout step or by exposure to ultraviolet light, depending on the type of mask on the PWB.
The ultimate pressure of less than <[10.sup.-6] Pa takes several days, but can be achieved faster by the use of available in-vacuum
bakeout lamps if necessary.
It provides complete process diagnostics and alarm displays, as well as adaptive wet heater
bakeout, and is available in 3- and 30-amp modules.
An investigation into the effect of "building
bakeout" conditions on building materials and furnishings.
This design provides a number of convenient benefits, including the ability to remove the motor during
bakeout, or any other time, without risking the loss of vacuum.
Through this period of growth, plastics had the advantages of broader bonding alternatives, better thermal shock and corrosion-resistance properties and less stringent
bakeout requirements.
D is the downtime given by, (3) D = TTOC/(TTOC + TTA) TTOC, typical time to return the machine from atmospheric pressure to operating conduction, includes the time it takes to perform effusion cell recharging, maintenance, pump-down,
bakeout and effusion cell conditioning.
