How do you get gold out of circuit boards without chemicals

Now let’s use a new method with salt and vinegar. First, pour sea water into a cup, pour in the vinegar and stir until the salt has melted. Vinegar and salt are a valuable but non-corrosive pickling solution needed to pickle tiny bits of gold on computer parts.

How do you clean gold off circuit boards

Clear the boards
In another pack, mix two parts of hydrochloric acid, one part of weak hydrogen peroxide (three percent concentration). Pour this concoction on the Circuit community forums to keep them completely swamped. Wait a week and rock the boat every day with a glass or plastic rod.

Will vinegar dissolve gold

Gold is not affected by vinegar as it is a very stable metal and does not react with oxygen. This means that it cannot discolor, form crystals, decompose or decompose.

Why is a series resonant circuit called an acceptor circuit & parallel resonant circuit is called Rejecter circuit

Since the series resonant circuit is used only at the resonant frequency, this manipulation of the circuit is called its acceptor circuit, because at resonance the impedance of the circuit usually reaches its minimum and thus easily accepts one of our currents whose frequency is equal to the frequency. equal to its resonant frequency.

Why the series resonance circuit is called an acceptor circuit and the parallel resonance circuit is called Rejector circuit

Himanshu replied: A series resonant circuit becomes acceptor because if your current applied voltage consists of a range of frequencies, the circuit can only accept the maximum current for all resonant frequencies and reject many other frequencies.
