SMALL SIZE REFLOW OVEN WITH COMPUTER AND RAIL
Up and bottom with 12 heating zones
Product background :
Reflow soldering is a delicate process, and the biggest advantage of this technology is that it can weld the electronic components to the circuit board on some small circuit boards, so as to meet the needs of enterprises for the circuit board.In the early eighty s, the electronics or use one of the most common ordinary welding to electronic components to the circuit boards, but with the development of science and technology, electronic technology continues to improve, circuit board has been more and more exquisite, the usual welding method in cabinet welded on the circuit board, therefore, the emergence of reflow soldering technology is the trend of The Times.
The unique advanced long life heating system
1.The heating system adopt the Swedish nickel heater with efficiency and energy-saving. The peak wave length of the radiation power is 4UM with curved surface reflector to the rising temperature speed, improve the thermal efficiency. And the special forced-air circulation system make PCB and the component heated uniform and eliminate the "shadow effect" completely .
2.Using special high temperature resistant protection system in heating preservation system and special iron in furnace .
3.Using imported Taiwan SanYue long axis of high temperature fan motor and W shaped heat pipe, Model design, no noise, shockless and easy for maintenance .
4.Whole oven are porous aluminum transfer the hot air to guarantee the hot air evenly to the PCB .the whole top oven fixtures can open completely so that easy to clean the oven inside .
Influence process factor
In SMT reflow welding process, the main reasons for uneven heating of components are: the difference of heat capacity or heat absorption of reflow welding components, the influence of conveyor belt or heater edge, and the load of reflow welding products.
1. Generally, PLCC and QFP have larger heat capacity than a discrete chip element, and it is more difficult to weld large area elements than small ones.
2. In the reflow welding furnace, the conveyor belt turns into a heat dissipation system when the reflow welding is carried out on the transmitted products. In addition, the heat dissipation conditions are different at the edges of the heating part and the center.
3. Different effects of product loading.Reflow soldering temperature curves should be adjusted to allow for good repeatability under no load, load and different load factors.Load factor is defined as: LF=L/(L+S);Where L= length of assembling substrate, S= interval of assembling substrate.
To get good repeatability in reflow welding process, the larger the load factor, the more difficult it is.Usually, the maximum load factor range of reflow furnace is 0.5~0.9.This depends on the product (component welding density, different substrate) and the type of reflow furnace.Practical experience is important for good welding results and repeatability
