We return electronics to life - we wash off the dust and displace water

    Hello to all Habra users!

    For a long time we did not tell anything about our decisions. We are corrected. Today we will talk about the two main enemies of any electronic device - dust and water and our ways of dealing with them.


    Is the video card very dusty?

    Turn off the computer, unscrew the wall, remove the board, turn on the vacuum cleaner ...
    For a long, uncomfortable, dust pillar ...

    There is another way - to "wash off" the dust. This method is especially convenient when it comes to expensive electronic stuffing, which, moreover, is not easy or even impossible to dismantle. At the same time, dust accumulation on it can lead to short circuit and breakage. And often it turns out that this is not a breakdown at all, but contacts got dusty and passed away.

    Dust should be washed off with a dielectric fluid, which, at the same time, leaves no residue on the surface and evaporates quickly. And also does not burn. At the same time, the dust does not scatter on all sides, but is “transferred” to the sponge in a directed flow or simply quickly drains from the part being cleaned.

    For example, one of my friends got a dashboard in a car. The bulb stopped turning on, but it should. He did not begin to remove the panel or contact the service, but washed it with a means for washing contacts. Just directed a stream of aerosol into the hole under the panel. Earned.

    Further more. At one of the mines, the displays of the frequency converters failed. Something like this:

    They were taken out, and without dismantling (!), They were washed with a contact cleaner. Of the six earned four. For the two remaining, apparently, there was simply not enough spray can :)

    And if you need to clean the inside of the electrical cabinet from dust? Switchgear?

    You can also use the contact cleaner. In this case, you can not turn off the voltage, since the liquid, I repeat, is an insulator. Also, it does not spoil the plastic and does not wash away the markers.

    And so, instead of accumulating and then trying to blow off the dust, we wash it off - without disconnecting the device from the network!

    Also, the contact cleaner will cope with pollution from low-viscosity, "light" mineral oils and silicones.

    Such contaminants and dust must be periodically removed when servicing aircraft, dashboards, and civil and military aircraft.

    What to do if your favorite iPhone drowned?

    Or spilled tea on your favorite mouse? Or a keyboard? Or a stereo?

    It is better to try to quickly disconnect from the voltage and remove the water. And it flows into any cracks, even the smallest - under the influence of capillary forces.

    And wait until it evaporates from there ... corrosion is inevitable.

    There is a simpler way - to dry ... using a contact cleaner.

    Hydrofluoroether, firstly, does not mix with water, and secondly, it has a much lower surface tension and viscosity. It simply quickly penetrates into any, smallest holes and displaces moisture from there.

    Electronics saved!

    If a certain amount of stronger solvents, including isopropyl alcohol, is added to the hydrofluoroether, we will get an excellent flux remover. In this case, the aerosol remains a non-combustible azeotropic mixture!

    Works great on alcohol-rosin and non-wash fluxes, but it is better to rinse immediately after soldering.

    I hope this review is helpful.

    See you soon!
