Wave soldering welding interview direct contact with high temperature liquid tin, the production of materials and temperature settings solder melts the use of tin-silver-copper alloy is the most important stage, wave soldering, welding surface of the plug-in board with high temperature liquid directlytin contact reach welded purpose high temperature liquid tin maintain a ramp by a special device to form a road similar to the waves of the liquid tin, so called "wave soldering wave soldering With the enhancement of people's awareness of environmental protection has a newwelding process. Previous tin-lead alloy, but the lead is a heavy metal great harm to the human body. So now have a generation of lead-free processes. It uses a higher preheat temperature * tin-silver-copper alloy * and special flux and soldering temperature requirements, but also to say that, over the welding area on the PCB board to set up a cooling zone workstations to to prevent thermal shock, on the other hand, if there are ICT, if interested in detecting influential.
Wave soldering flux active phase first must have the appropriate time and temperature, allowing the completion of the cleaning stage in the solder particles just begin to melt. Secondly, fully heated slowly to secure the solvent was evaporated, to prevent tin beads formed and limitations of the components caused by the internal stress due to the temperature expansion, causing reliability problems off cracks. The time-temperature curve, the solder melted stage is the most important, and must be sufficient to allow the solder particles is completely melted, liquefied forming a metallurgical welding, residual solvent, and flux residue and evaporated and the surface of the formed solder pin. This stage is too hot or too long, may damage components and PCB.
