RF 400A IR Lead Free Wave Solder Machine For SMT Welding Line
Lead Free IR Wave Solder RF-400A Wave Welding Machine for SMT Line
The Solder Joint Information of Wave Soldering Machine
Wave soldering machine solder joint formation: When the PCB enters
the front end of the wave surface, the substrate and the pins are
heated, and before leaving the wave, the entire PCB is immersed in
the solder, that is, bridged by the solder, but at the moment it
leaves the end of the wave , A small amount of solder adheres to
the pad due to the wetting force, and due to surface tension, a
small state of shrinkage with the lead as the center appears. At
this time, the wetting force between the solder and the pad is
greater than the two pads The cohesion of the solder between.
Therefore, a full, round solder joint will be formed, and the
excess solder leaving the wave tail will fall back into the tin
bath due to gravity.

What we should concern at the operation progress of wave solder ?
1.The product should be wave soldered and inspected (after all
soldering parameters reach the set value)
Place the printed circuit board gently on the conveyor belt (or
fixture), the machine will automatically spray rib flux, preheat,
wave solder and cool; the printed circuit board is connected at the
wave solder outlet; according to factory inspection standards.
2.Adjust the welding parameters according to the PCB welding
results
3.Carry out continuous soldering production, connect the printed
circuit board at the exit of the wave soldering, put it into the
anti-static turnover box after inspection, and send the repair
board for subsequent processing; during the continuous soldering
process, each printed board should be checked for soldering defects
Serious printed boards should be re-soldered immediately. If there
are still defects after welding, the cause should be found out, and
the process parameters should be adjusted before continuing
welding.
