Abstract
The utility model relates to a BGA (Ball Grid Array) repair work station, and especially relates to a BGA repair work station airflow control system therein. The BGA repair work station airflow control system mainly comprises an air compressor, an oil-water separator, a filter, a pressure-reducing valve, a mass gas flow meter, a controller, a pressure sensor, a vacuum suction nozzle, and an electromagnetic valve. The BGA repair work station airflow control system controls an air flow of a heating system through the mass gas flow meter, and adsorbs a chip through the vacuum suction nozzle to perform dismounting and mounting. The BGA repair work station airflow control system of the utility model can effectively control airflow needs of the BGA repair work station based on any adverse effect.
Description
Technical field
The utility model relates to a kind of BGA reclamation work station jet system
Background technology
The circuit board that every needs are reprocessed all can have following characteristics, PCB or components and parts costliness and limited amount, and product only in this way just can take into account and reprocesses, and possesses the value of reprocessing.Thus, seem extremely important for the protection of PCB and components and parts, and unfavorable temperature and unfavorable installation and removal operation can cause their damage.So the technology of reprocessing of BGA just is how BGA device not damaged is disassembled from PCB, newer device is mounted up exactly and carry out high quality welding.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art, the purpose of the utility model is to provide a kind of BGA reclamation work station jet system.
To achieve these goals, the technical scheme of the utility model employing is:
A kind of BGA reprocesses the station jet system, comprises the air compressor, oil water separator, filter and the pressure-reducing valve that are connected successively, and the pressure-reducing valve outlet is quality of connection gas flowmeter and controller respectively; The mass airflow meter is connected with vacuum slot, and controller is connected with pressure sensor, and pressure sensor connects electromagnetically operated valve; Said air compressor is a source of the gas; Purify through oil water separator and filter, by pressure-reducing valve air pressure is controlled at rated range, air-flow divides two parts as required afterwards; By controller and solenoid control AFS; A part is accurately controlled the wind flow of heating part by the mass airflow meter, and a part is moved towards vacuum slot, adsorbs the chip dismounting or mounts.
Adopt the mass airflow meter that the wind flow of heating system is controlled, and solve the air-flow offset problem.
When vacuum slot was taken element away, pressure sensor detected pulling force, set maximum force value through controller, when pulling force that element bears is in this value scope, allowed behaviour to do execution, when exceeding this value, abort operation.So just can also not melt and just directly broken, cause the damage of components and parts and PCB pad because of indivedual solder joints.
The utility model is compared with prior art; Following beneficial effect is arranged: the utility model can effectively be controlled the stream pressure size, and different purposes are arranged on same equipment, can blow out simultaneously and the vacuum suction function; Automaticity is high, is convenient to be connected realization with computer and controls automatically.
Description of drawings
Accompanying drawing is the utility model work sketch map.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is explained further details.
As shown in the figure; A kind of BGA reprocesses the station jet system; Comprise the air compressor, oil water separator, filter and the pressure-reducing valve that are connected successively, the pressure-reducing valve outlet is quality of connection gas flowmeter and controller respectively, and the mass airflow meter is connected with vacuum slot; Controller is connected with pressure sensor, and pressure sensor connects electromagnetically operated valve.
Air compressor is the air-flow source; Purify through oil water separator and filter; By pressure-reducing valve air pressure is controlled at rated range, air-flow flows to two parts after getting into BGA reclamation work station as required, and a part is used for the air-flow of heating part; A part is used for vacuum slot, adsorbs chip and dismantles or mount.
Pressure sensor, the pressure limit when being used to detect vacuum slot absorption element, controller control electromagnetically operated valve is made the action that allows operation or abort operation.
The mass airflow meter is used for the wind flow of heating system is controlled, and solves the air-flow offset problem.Since the solder joint of BGA all be designed into element below, controlled hot blast mode can avoid component body must bear the temperature greater than solder joint around below element, heating, and has reduced to damage the possibility of components and parts greatly.
Air compressor is the air-flow source; Purify through oil water separator and filter; By pressure-reducing valve air pressure is controlled at rated range, air-flow flows to two parts after getting into BGA reclamation work station as required, and a part is used for the air-flow of heating part; A part is used for vacuum slot, adsorbs chip and dismantles or mount.The air communication that is used for heating part is crossed the mass airflow meter, and the wind flow of heating system is controlled, and makes the controlled hot blast mode can be around below element, heating, and adjustment air-flow offset problem.Be used for vacuum slot; The air-flow that adsorbs the chip dismounting or mount; When vacuum slot adsorbed, the pressure limit when detecting the absorption element by pressure sensor fed back to controller; The control electromagnetically operated valve is made the action that allows operation or abort operation, to being adjusted to the work of rated pressure scope continued.
The preferred embodiment of more than introducing that only is based on the utility model can not limit the scope of the utility model with this.Any the utility model is done replacement, combination, the separation of parts well know in the art, and the utility model implementation step is done that well know in the art being equal to changes or replacement does not all exceed the protection range of the utility model.
