    Wave soldering is an in-line process in which the underside of the circuit board is treated with flux, then preheated and dipped in liquid solder. In the next step, the plate is cooled. This is the core of the entire wave soldering process. With a machine, this process is performed. Here is a step-by-step explanation of how the wave soldering machine works:

    Step 1 – Melt the solder

    This is the very first step in the entire wave soldering process. It is the basic requirement of the process of melting the solder. In the wave soldering machine, Lot is in a tank. The tank is heated to melt the solder. The appropriate temperature is reached to achieve the correct consistency so that the soldering process can be continued.

    Step 2 – Clean the components

    This is a very important step. The components to be soldered are thoroughly cleaned in this step. If oxide layers form on the components, they are removed. This is done by the process called Fluxing. There are two main types of flux – corrosive (high acid content) and non-corrosive (high acidity).

    Step 3 – Placement of the circuit board

    After melting the solder and cleaning the components to be soldered, the circuit board is placed on the molten solder. The board is held with the metal clamps of the machine, which ensure a firm positioning and placement of the board.

    Step 4 – Apply the solder

    After the board has been placed correctly, molten solder is applied and allowed to settle. Sufficient time is allowed for this step so that the solder settles completely in the joints and no bumps occur.

    Step 5 – Cleaning

    This is the last step in the wave soldering process. Flux residues generated during the process are cleaned in this step. The circuit board is washed and cleaned with deionized water and solvents.
