Desk wave soldering machine in electric industry for SMT
Desk wave soldering machine
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 production.
Ⅱ Main 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： eight： 48Kg
There are 6 parts: flux, preheating, soldering, electrical controlling, exhaust unit and convection unit.
1. Flarts are made of air pump, air tube, pin valve, filter, froth tube and flux box, 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
4. exhaust unit
It is made of cover, air fan, air cover and air tube. All exhaust generated in soldering will be eliminated.
5. 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.
