Abstract
The apparatus thereof comprises supporter, container, liquid media, thermocouple and heating unit. The U shaped heating wire is used to heat the liquid media up to a certain temperature, and then the one side of the PCB, which has solder, is placed on the surface of the liquid media but not immersed into the liquid media; when the solder is solved in the liquid media, namely the separation between the PCB and the components is completed, the PCB is taken out from the liquid media.
Description
Affiliated technical field
The present invention relates to a kind of printed substrate and the separating technology that components and parts separate, especially can not produce the isolation technics of toxic gas and highly effective and safe.
Background technology
At present, printing circuit board component separates the general roasting plate separation of adopting, and be about to printed substrate and be placed on the stove, because the fusing point of scolding tin is lower, when temperature reaches certain, the scolding tin fusion, components and parts separate with printed substrate.But,, cause lead poisoning and air pollution easily owing to contain a certain amount of toxic metals lead in the scolding tin.
Summary of the invention
For fear of having the harm that printed substrate and components and parts isolation technics are caused now, the invention provides a kind of separating technology, this separating technology can not only separate printed substrate with components and parts fast, and can not cause environmental pollution.
The technical solution adopted for the present invention to solve the technical problems is: this printed wire panel element separator mainly is made up of outer casing stand, container, liquid medium, thermocouple and heater.Before using container is placed on the outer casing stand, then thermocouple and U type heating wire is fixed on the support together, in container, inject transmitting medium again.Use energized, setting can make the temperature of scolding tin fusion, when reaching, temperature sets that signal lamp brightens when requiring, the one side that at this moment printed substrate can be contained scolding tin is placed the liquid medium surface and is not immersed, by the time after the scolding tin fusion printed substrate is taken out, slightly beaing printed substrate can separate components and parts, reaches the purpose that printed substrate separates with components and parts.
The invention has the beneficial effects as follows, can when separating printed substrate and components and parts, only utilize the heat conduction of liquid medium, simple in structure, just with operation.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the three-dimensional structure diagram of device therefor of the present invention.
1. outer casing stands among the figure, 2. container, 3. thermocouple, 4.U type heating wire, 5. signal lamp is 6. transferred knob.
Embodiment
In Fig. 1, in container (2), add liquid medium during use.Set the temperature of required heating by transferring knob (6), with U type heating wire (4) heating liquid medium, measure the temperature of liquid medium by thermocouple (3), when signal lamp when temperature reaches design temperature (5) is bright, the one side that the printed substrate that will separate contains scolding tin is put into container (2) to liquid surface, take out after heating a little time, slightly beat printed substrate.
Claims (4)
1. printing circuit board component separating technology, its equipment is made up of support, container, liquid medium, dividing plate and heater, it is characterized in that: by heater liquid medium is heated to more than the scolding tin melting temperature, printed substrate is placed on the liquid medium surface.
2. according to the said printing circuit board component separating technology of claim 1, it is characterized in that: liquid medium is one or more the liquid of boiling point between 150 ℃ and 350 ℃.
3. according to the said printing circuit board component separating technology of claim 1, it is characterized in that: heater is one group of heating wire.
4. according to the said printing circuit board component separating technology of claim 1, it is characterized in that: make the scolding tin fusion by liquid medium conduction heating.
