Time Temperature setting wave soldering is the most important in the solder melts |
Wave soldering welding interview direct contact with high temperature liquid tin, the production of materials and temperaturesettings solder melts the use of tin-silver-copper alloy is the most important stage, wavesoldering, welding surface of theplug-in board with high temperature liquid directlytin contact reach welded purpose high temperature liquid tin maintain aramp by a special device to form a road similar to the waves of the liquid tin, so called "wave soldering wave soldering Withthe enhancement of people's awareness of environmental protection has a newwelding process. Previous tin-lead alloy, butthe lead is a heavy metal great harm to the human body. So now have a generation of lead-free processes. It uses a higherpreheat 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. |
