Description
Technical field:
The utility model relates to the chip extracting tool, relates in particular to a kind of extracting tool that is mainly used in the various standard specification chips of DIP encapsulation on the disconnect circuit plate.
Background technology:
Characteristics such as electronic product is economical and practical because of it at present, effect is remarkable, it uses each corner and the stratum that has been deep into society, produces, lives and bring great convenience to people.Yet along with a large amount of uses of various electronic products, produce the discarded object of various electronic circuits therefrom, stayed serious environmental issue to us.Yet many times, because other components and parts are damaged, met with discarded on the circuit board in view of maintenance difficult.In fact, most circuit board can be repaired by the method for changing chip, and in addition, since the update of product above it incidental electronic devices and components still meet the requirement of serviceability, these electronic devices and components can be recycled again by dismounting, to reduce the discarded wasting of resources and the environmental pollution that causes owing to electronic devices and components.DIP (DualIn-line Package) is meant employing dual-in-line form packaged integrated circuits chip, and most middle small scale integrated circuits (IC) all adopt this packing forms, and its number of pins generally is no more than 100.Adopt the cpu chip of DIP encapsulation that two row's pins are arranged, need be inserted on the chip carrier socket with DIP structure.Weld on the circuit board that certainly, also can directly be inserted in identical welding hole number and arrange for how much.The chip of DIP encapsulation is being answered SC when chip carrier socket plugs, in order to avoid damage pin.
Very inconvenience of the method for dismounting of circuit chip on board now, and the serviceability of the easy defective chip of unloading process that reclaims at circuit chip and the pin part of chip make the dismounting of chip be recycled into motility rate and have a greatly reduced quality.
The utility model content:
Shortcoming at prior art, the purpose of this utility model provides a kind of general-purpose tool for extracting DIP packed chip, the chip of the DIP encapsulation of detachable various standard specification models, and make the chip of dismounting can keep serviceability originally and the integrality that keeps each several part.
To achieve these goals, the technical solution of the utility model is: a kind of general-purpose tool for extracting DIP packed chip, comprise heating part, and described heating part is connected with a heating head, is provided with two molten tin-tube pin slots on this heating head surface.
Described heating part is the temperature control heating part, comprises temperature control electric soldering iron and pitman, is provided with the long tube of thin-walled at described pitman one end, and its endoporus is nested in the heating rod of described temperature control electric soldering iron, and the other end of pitman is connected with described heating head.
Between described pitman and the heating head is to be threaded.
On described pitman, be provided with external screw thread, be provided with the internal thread that is connected with described external screw thread in the center of described heating head.
Described heating head comprises the replaceable heating head of plurality of specifications size, and the length and the distance of the molten tin-tube pin slot of two symmetries of each heating head differ.
It is characterized in that described heating head is the copper alloy heating head.
Be connected with an antistatic ground wire on the described temperature control electric soldering iron.
The utlity model has following advantage and implementation result
1, utilizes temperature control electric soldering iron can realize the temperature of heating part is controlled, be convenient to the dismantlement work under corresponding various circuit chip and the varying environment.
2, relatively tradition use the common electrical flatiron one by one pin melt the tin dismounting, extracting tool heating head surface is provided with two molten tin-tube pin slots, it carries out instantaneous molten tin to chip pin simultaneously and heats, and can realize dismantling the chip purpose at short notice.
3, reclaim in the industry at chip, traditional relatively fiery roasting method that uses, efficient of its dismounting chip is higher, but survival rate of its dismounting chip is lower, and because the fiery roasting overheated generation harmful substance of device that can cause on some circuit board has a strong impact on environment.Extracting tool is concentrated heating by the molten tin-tube pin slot of heating head to the scolding tin at chip pin position, has avoided the destruction to other components and parts of circuit board; The temperature control of extracting tool by temperature control electric soldering iron, make chip pin scolding tin can be under the damage temperature of chip instant melting, the instantaneous dismantlement work of finishing chip has been avoided having improved the survival rate of dismounting chip owing to be heated and defective chip for a long time.

The specific embodiment:
See also Fig. 1 to Fig. 5, the temperature control heating part 2 of present embodiment combines with the internal thread coupling part 12 at heating head 1 center with the external screw thread coupling part 212 of pitman 21, forms complete extracting tool.In use, as thermal source, the heat of its generation is delivered in the body of heating head 1 by heating pitman light-wall pipe 211 with temperature control electric soldering iron 22.Heating head 1 will transmit the heat that comes by body and focus in the molten tin-tube pin slot 11, as shown in Figure 5, the molten tin-tube pin slot 11 of heating head 1 contacts with the pin of DIP packaged chip, the pin of molten 11 pairs of chips of tin-tube pin slot heats simultaneously, make the scolding tin of pin under the molten Xi Wendu of heating head 1, melt, use tweezers just can easily take off chip 3.Because 1 pair of scolding tin of heating head has the good adsorption ability, can clear up recovery to the scolding tin in the heating first melt tin-tube pin slot 11 by corresponding solder sucker.
Present embodiment is that the heating rod by temperature control electric soldering iron heats, and carries out the heating-up temperature regulation and control with the temperature regulating switch of temperature control electric soldering iron.Temperature control electric soldering iron and heating head pitman make up, and can select the electric iron of different capacity according to the needs of actual operating position for use.Pitman one end is provided with the long tube of thin-walled, and its endoporus directly is nested in the heating rod of electric iron, thereby has accelerated the heat conduction efficiency of heating rod and significantly reduced the thermal loss in the heating process, improves the preheating speed of heating head.
The heating head part can comprise the replaceable heating head of plurality of specifications size, and the chip of corresponding different size model can adopt the heating head of corresponding specification.Heating head joins with the heating pitman by the internal thread in centre, temperature control electric soldering iron energising heating, and the heat that is produced is sent to heating head by the conduction of heat of heating pitman.Heating head adopts the Cu alloy material manufacturing, in the heat that heating head acceptance heating pitman passes over, the form that heating head is concentrated with heat gathers heat rapidly in the molten tin-tube pin slot of chip, in the warm of tool set, reach the effect of Fast Heating, and can improve the survival rate of chip in the dismounting removal process greatly at the scolding tin on the instant melting chip pin.In addition, the manufactured materials of heating head is a copper alloy, and it produces suction-operated to scolding tin in scolding tin heating process, makes that the scolding tin on the chip pin reaches transfer significantly, by collection, can realize reclaiming the purpose of scolding tin to scolding tin in the heating first melt tin-tube pin slot.Can dismantle the DIP encapsulation components and parts of various sensitivities by in conjunction with temperature control electric soldering iron antistatic ground wire.Also can select to be fit to the heating head of specification, the colour circle resistance and the electric capacity of marshalling are dismantled.
