crafting process

After the board enters the wave soldering machine through the conveyor belt, it passes through some form of flux coating device where the flux is applied to the board by means of crests, foaming or spraying. Since most fluxes must reach and maintain an activation temperature during soldering to ensure full solder joint penetration, the board must pass through a preheat zone before entering the crest. Preheating after flux application can gradually raise the temperature of the PCB and activate the flux. This process also reduces the thermal shock that occurs when the assembly enters the peak. It can also be used to evaporate all possible absorption of moisture or carrier solvents that dilute the flux. If these things are not removed, they will boil over the peak and cause solder sputter, or steam will remain inside the solder to form a hollow. Solder joints or trachoma. In addition, because the heat capacity of double-sided and multi-layer boards is larger, they require a higher preheating temperature than a single panel.

At present, wave soldering machines basically use heat radiation for preheating. The most commonly used wave soldering preheating methods include forced hot air convection, convection of electric heating plates, heating of electric heating bars and infrared heating. In these methods, forced hot air convection is often considered to be the most efficient heat transfer method for wave soldering machines in most processes. After preheating, the board is soldered with single-wave (lambda) or double-wave (spoiler and lambda) waves. A single wave is sufficient for a piercing element. When the circuit board enters the peak, the direction of solder flow is opposite to the direction of travel of the board. Eddy currents can be generated around the component pins. This is like a scrubbing process that removes all of the above flux and oxide film residues and forms infiltration when the solder joint reaches the infiltration temperature.

For mixing technology assemblies, spoiler waves are generally used before lambda. This kind of wave is narrow, with high vertical pressure during perturbation, which allows the solder to penetrate well between the compact pin and the SMD pad, and then uses λ waves to complete the solder joint formation. . Before making any assessment of future equipment and suppliers, it is necessary to determine all the specifications of the board soldered with the wave peaks, as these can determine the performance of the required machine.
