In the past it was the problem does not clear after the circuit board soldering. clean lehimliyordum finishings hand prone to it:), but it’s not even the jobs guarantee problems by chance after seeing the problems with soldering circuit card I got into the habit of cleaning, repair, construction of the circuit doesn’t matter sometimes employs one-time soldering, such as resistors, capacitors, I forget, but I’m sure after cleaning the integrated soldering
I’ve been using this for work have different chemicals like isopropyl alcohol sellozik thinner, but I couldn’t find anything already in effect cheap sellozik thinner too, but apart from a few strange brands on the market, even thought there are already many different card glutinous kokularıda anyway sellozik immediately away from the smell of paint thinner as you can while cleaning if you have to breathe to do this work in the open air, open the window or balcony, do I go cleaning cleaning the window, at the bottom of the cards more than one card in particular Scotland-Paolozzi Studio recreation clean and fan I’ve been using
As you can see in the picture below, sometimes only the short circuits can soldering soldering is not invisible after the table with that tiny pieces on the wires, make sure that the problem is worse than that so they can grow short circuits saw:)
TDA7490 Class-D Amplifier Project The output stage of the TDA7490 amplifier in class D The core of the end stage class d circuit is TDA7490 from the company STMicroelectronics. The way in which this amplifier works, was discussed above. Here will be dismantled just a function nejdůleţitějších components. On pin 8 generates a modulation signal, or it is possible for him to bring an external modulation signal. The frequency of the generated signal is according to given the values of capacitor C17 and resistor R13 according to equation.
