The smaller diode precision welding stove cooling system of demand, good cooling results.
Background technology
There is one of diode chip components welding process during diode production, lead, weld tabs and silicon grain are overlapped
Afterwards, it is placed in welding diode stove and is welded.On diode automatic assembly line, assembled diode chip component is inserted in
On welding diode mold, slowly constantly it is sent into diode die welding furnace burner hearth by automatic assembly line conveyer belt, in stove
Temperature be up to 300 more spend, transmission speed be generally it is 100-200 millimeters per minute, in the soldering furnace of burner hearth both ends fire door open type
Welding, in order to make the metal material on die assemblies not aoxidized at high temperature, must inject abundant nitrogen, shape in burner hearth in stove
The environmental protection of pairs of product, just can guarantee the welding quality of diode chip under such environmental protection.Go out from soldering furnace
What is come is the first finished product with high temperature, is badly in need of cooling.
It after welding diode is complete, needs to be quickly cooled down, the high temperature that diode temperature is spent out of soldering furnace 300 more is cold rapidly
But normal temperature state is arrived.As shown in fig.1, for the schematic diagram of traditional cooling system, which is sleeved on furnace body by water jacket
Appearance passes to recirculated water in water jacket, and water jacket one end is equipped with water inlet 11, and the other end is equipped with water outlet, and centre was water
Layer, which is that single head goes out into single head, and water will completely overflow.As shown in fig.2, improving cooling system to be preliminary
Schematic diagram, this tentatively improves cooling system in such a way that flow is looped around furnace body in appearance, water from water inlet 21 enter,
It is flowed out from water outlet after furnace body, the disengaging mode of water is also that single head goes out into single head.Above two cooling system, water are all single
Head disengaging, due to import and export only there are one, water velocity is very slow so that water cools down inefficiency, and is difficult to realize to cold
But the control of water temperature.
Above-mentioned existing cooling system cooling velocity is slow, and water demand is bigger, and coolant water temperature is difficult to control.Due to cooling
The unstable welding quality for being allowed to product of temperature it is poor, for needing the welded bands of electronic product of 0 Ohmic contact to carry out many
