It is previously described in the electric iron of integrated circuit sealing-off and welding, the end of the capillary is equipped with inclined-plane.
Compared with prior art, the present invention is with multiple capillaries, and after the state for adjusting each capillary, the present invention can be simultaneously
Sealing-off is carried out to row's pin and welding, working efficiency are higher.When carrying out sealing-off, spring leaf withstands the side of integrated circuit
Wall, when scolding tin melts, worker need not be gone to remove integrated circuit from circuit board with hand, and spring leaf can be by integrated electricity
Road flicks, so when sealing-off, worker will not be burned.When welding, by spring pressure at the top of integrated circuit,
Worker need not pin integrated circuit with hand, and worker will not be burned.The present invention has multiple capillaries, and a part of capillary is turned over
Turn, the gap formed after overturning is identical as pin spacing on integrated circuit, so that it may to carry out sealing-off and welding to integrated circuit, by
In capillary, unrestricted choice is overturn according to demand, so the integrated circuit of different pin spacing can carry out sealing-off through the invention
And welding, so the present invention is suitable for sealing-off and the integrated circuit range of welding is wide.
Therefore, the present invention has the advantages that working efficiency is higher and will not cause scald accident, and suitable for sealing-off and
The integrated circuit range of welding is wide.

Specific implementation mode
The present invention is further illustrated with reference to the accompanying drawings and examples, but be not intended as to the present invention limit according to
According to.
Embodiment.A kind of electric iron for integrated circuit sealing-off and welding, as shown in Figure 1, including handle 1, handle 1
Lower end be equipped with heat-dissipating pipe 2, the lower end of heat-dissipating pipe 2 is fixed with calandria 3,3 vertical heat-dissipating pipe 2 of calandria, is set on calandria 3
There is the power cord 4 across heat-dissipating pipe 2 and handle 1；3 end of calandria is fixed with baffle 5, and baffle 5 is equipped with and extends to heat-dissipating pipe 2
And the thermal insulation board 6 of semi-surrounding calandria 3；Calandria 3 be equipped with row needle 7, row's needle 7 by multiple arranged in co-axial alignment and be set in plus
Heat conduction ring 9 on hot body 3 forms, and heat conduction ring 9 is equipped with capillary 10, and row's needle 7 is connect by disk spring 8 with baffle 5.
The end of the heat-dissipating pipe 2 is equipped with spring leaf 11, and the spring leaf 11 is arc, strip, and is rolled to row's needle 7 one
Tiltedly.
The end of the capillary 10 is equipped with inclined-plane 12.When worker is hand-held of the invention, the present invention and horizontal plane are by one
Determine angle, inclined-plane 12 is by the direct contact surface of heat transfer pin, and at this time inclined-plane 12 is in horizontality, that is, ensures
Large contact between inclined-plane and pin, heat transfer efficiency is high, is conducive to improve working efficiency.The calandria 3 is existing
There is common calandria on electric iron, such as electric-heating-wire-heating body and PTC calandrias.The heat-dissipating pipe 2 is for preventing from heating
The heat transfer of body 3 prevents hand from scalding to handle 1.
Operation principle：Power cord 4 is connected into power supply, calandria 3 heats, and heat is transferred to capillary 10, capillary through heat conduction ring 9
10 and pin be in direct contact thawing scolding tin, sealing-off and welding are carried out to integrated circuit.There are two the effects of the thermal insulation board 6：One
It is the heat reflection for radiating a part, reduces heat and distribute, keeps capillary 10 to be in and be not easy to cool down, second is that playing limit
Effect, the lower edge of thermal insulation board 6 withstand capillary 10, prevent capillary 10 when sealing-off and welding by the reversed force effect of pin
And it rotates.
The operating process of sealing-off：The spacing for measuring the pin on the integrated circuit of damage adjusts each according to pin spacing
The state of capillary 10 overturns capillary 10, so that capillary 10 is divided for two parts, capillary upward and capillary directed downwardly, weldering directed downwardly
Gap is identical as pin spacing between needle, then will be directed downwardly then by the side wall of the end iron jail integrated circuit of spring leaf 11
Capillary alignment pins simultaneously contact, and when the scolding tin at pin melts, are unclamped between integrated circuit and circuit board, integrated circuit
It is flicked by spring leaf 11, completes sealing-off.
The operating process of welding：It, then will be new first with tin on common electric iron on the pin of new integrated circuit
Integrated circuit is put back on circuit board, then hold the present invention move from top to down, spring leaf 11 first pins integrated circuit, then after
Continuous to move down, capillary directed downwardly contacts the pin on integrated circuit and melts scolding tin, then spring leaf 11 is being kept to continue to press
Firmly under the premise of integrated circuit, capillary directed downwardly and pin are disengaged, after soldering tin binds, that is, complete welding.
When capillary directed downwardly is to carrying out sealing-off and welding, the edge that capillary side directed downwardly is pushed up by thermal insulation board 6 is withstood,
So capillary directed downwardly will not excessively be overturn, ensure that sealing-off is smoothed out with what is welded.
The present invention has the advantages that working efficiency is higher and will not cause scald accident, and is suitable for sealing-off and welding
Integrated circuit range is wide.
