Definitions
- N 2 -O 2 atmospheres typically having O 2 limit contents respectively. a few% in one case and a few thousand ppm in the second case.
- several means of depleting O 2 in the source air can be used: cryogenic distillation, adsorption of oxygen on a catalytic bed, combination of oxygen with a another gas, or selective permeation through a membrane.
- the air is depleted in O 2 to obtain a first gas mixture with an O 2 content of less than or equal to tl, - part of this first gas mixture is used to supply the first working gas,
- the device can include one or more of the following characteristics:
- This device is intended to provide the working atmospheres of a reflow soldering furnace 9 and of a wave soldering machine 11, forming part of an installation for assembling electronic components.
- the electronic components are stored before being assembled in the reflow oven 9 or in the wave soldering machine 11, is carried out in the enclosure 7 for storing electronic components, located upstream of the means 1.
- the second depletion means 3 O 2 using a conventional method of catalytic combination of oxygen with hydrogen to form water.
- These means 3 comprise a dryer making it possible to condense the water produced, discharged at 6, and to obtain a gas depleted in O 2 at their outlet 10.
- the mixture N 2 ⁇ 0 2 produced at the outlet 10 of the means 3 has a O 2 content close to 50 ppm, directly supplying a wave soldering machine 11 of electronic components.
- the permeate mixture obtained at the second outlet 14 of the first O 2 depletion means 1 is oxygenated air having an O 2 content close to 25%, used to supply a unit 17 consuming oxygenated air.
- FIG. 2 illustrates a case of using first (1A), second (IB) and third (5) means of oxygen depletion, respectively: a membrane separator 1A, making it possible to produce, at its residual outlet 2 , a gas mixture N 2 -O 2 with a residual oxygen content close to 10%, in order to supply with this mixture a component storage enclosure 7; a membrane separator IB, making it possible to produce, at its residual outlet 10, a gaseous mixture N 2 -
