The design of wave soldering roughly elements are inserted in the corresponding component hole ?
precoated flux preheat (90 to 100 ° C temperature, length 1-1.2m) ? (220-240 ?) wave soldering cooling ? removal of excess plugfeet ? check. And wave soldering materials, mechanical and electrical connection between the surface mount components weld ends or pins and printed circuit board pad soldering. Wave soldering [1] As people's awareness of environmental protection has been a new welding 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.
for manual welding 99.3Sn/0.7Cu alloy system.
