Wave soldering welding interview direct contact with high temperature liquid in the production
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  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.
Wave soldering machine welding assembly material:
a lead-free wave soldering machine PCB manufacturing process;
b in the solder paste the application of 96.5Sn/3.5Ag and 95.5Sn/4.0Ag/0.5Cu eutectic and approximate eutectic alloy system;
for wave soldering applications 99.3Sn/0.7Cu eutectic alloy system;
for manual welding 99.3Sn/0.7Cu alloy system.
