[0002] Wax dipping of circuit boards means heating and melting paraffin into wax liquid according to the required process ratio, then immersing the circuit board in the wax liquid for a certain period of time, taking it out and letting it stand. After the wax liquid on the circuit board cools down, a layer of wax film will form on the surface of the circuit board, thus forming a wax-dipped circuit board.
