Desk wave soldering machine TB680 has been developed by Torch, It
is the first equipment in small type wave soldering field. TB680 is
suitable for research center, war industry, middle- and small-sized
corporation, small private corporation and other electronic
production companies. It is a desk-type, taking up small room, with
multi-functions, energy-saving and high efficiency. The operation
is easy and especially suitable for small and middle batch
ⅡMain technology parameters
max power： 3KW
pot capacity： 37Kg tin
max PCB size： 200X270mm (max)
temperature range： 200-300℃ LED display
preheating temperature： 70-90℃
height range of wave crest： 5-12mm
Melting time： 80min
flux spray ： froth
power supply： 220V±1%V AC single phase 50Hz
(please connect power to the ground)
transmission speed： 0.5-3m／min
dimension ： 850X600X330mm
net weight： 48Kg
There are 6 parts: flux, preheating, soldering, electrical
controlling, exhaust unit and convection unit.
Flux parts are made of air pump, air tube, pin valve, filter, froth
tube and flux box
There is flux belt on the froth tube, PCB whose side has chips is
on the top and touch flux, the side will has flux film.
It is made by melt board with resistor to provide heat for PCB.
It is made by tin pot, heating board, wave pump and tin.
Figure 3: The solder will be divided into upper and lower levels by
clapboard, the lower for the high-pressure layer, the upper layer
for the low-pressure layer, liquid solder will be into high
pressure layer driven by wave pump, the solder in the high pressure
layer rotate and then pass regulator, it will overflow from the
nozzle, the wave crest form and then fall into low pressure layer
because of gravity
4 electrical controlling
With modular structure, transmission speed, solder temperature,
preheating time and others can be adjusted and controlled. Working
principle is shown in Figure 4.
Figure 4 electrical controlling
- exhaust unit
It is made of cover, air fan, air cover and air tube. All exhaust
generated in soldering will be eliminated.
- convection unit
It is made of chain, rail, drive and pallet. PCB will be sent in
flux unit, preheating unit and soldering unit by convection unit.
