Abstract
The utility model provides a kind of chip spread sheet machine and comprises framework, the hair-dryer of framework underside and the gas flow detector of frame upper side, described framework is used for the chip of fixed plastics film and plastic film, arranging heater in the hair-dryer of downside further makes hair-dryer blow out hot blast, and whether the gas flow detector of upside can detect the air-flow at this place more than a setting threshold.The utility model has the advantage of, the hair-dryer of below can blow out hot blast, makes plastic film that arching upward upwards occur, and then drives chip to be separated, and realizes spread sheet; And whether the gas flow detector on top breaks for detecting plastic film, can be found when plastic film just breaks, and then stop blowing, control loss expands further.
Description
Technical field
The utility model relates to chip package field, particularly relates to a kind of chip spread sheet machine.
Background technology
Spread sheet refers to evenly separates arranging IC wafer closely, makes it to implant on welding work pieces better.Spread sheet technique is one of processing step indispensable in the packaging process of some particular semiconductor device.
Accompanying drawing 1 is the structural representation of a kind of common spread sheet machine in prior art, and comprise framework 10 and lifting holder 11, chip 13 is secured on plastic film 14, and is fixed on further in framework 10.Lifting holder 11 inside has heating arrangements (not shown).Framework 10 and chip 13 are placed in lifting holder 11 surface, lifting holder 11 is heated, and upwards rises same plastic film 14 and contact.There is elastic dilatation in the chip 13 on plastic film 14 surface, make chip 13 separately, and heating lifting holder 11 is conducive to soft plastics film 14 under the support of lifting holder 11, is beneficial to the separately more even of chip 13.
The shortcoming of prior art is, the combination of plastic film 14 and lifting holder 11 can not full symmetric, causes that plastic film 14 accepts inequality and deformation is uneven, and then chip 13 non-homogeneously to separate.And stressed being difficult to of plastic film 14 accurately controls, and easily causes plastic film 14 to break, cause spread sheet failure when being elevated holder 11 and excessively rising.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of chip spread sheet machine, can improve the success rate of chip spread sheet.
In order to solve the problem, the utility model provides a kind of chip spread sheet machine and comprises framework, the hair-dryer of framework underside and the gas flow detector of frame upper side, described framework is used for the chip of fixed plastics film and plastic film, arranging heater in the hair-dryer of downside further makes hair-dryer blow out hot blast, and whether the gas flow detector of upside can detect the air-flow at this place more than a setting threshold.
Optionally, the gas flow detector of upside comprises a siren, and implements alarm operation when exceeding this threshold value.
Optionally, described framework comprises a Flexible Connector further, for plastic film and the frame body of connection chip, to ensure that plastic film is separated to make chip can be there is deformation under heating state.
The utility model has the advantage of, the hair-dryer of below can blow out hot blast, makes plastic film that arching upward upwards occur, and then drives chip to be separated, and realizes spread sheet; And whether the gas flow detector on top breaks for detecting plastic film, can be found when plastic film just breaks, and then stop blowing, control loss expands further.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of a kind of common spread sheet machine in prior art.
It is the structural representation of this embodiment shown in accompanying drawing 2.
Embodiment
Elaborate below in conjunction with the embodiment of accompanying drawing to the chip spread sheet machine that the utility model provides.
Be the structural representation of this embodiment shown in accompanying drawing 2, comprise the hair-dryer 21 on the downside of framework 20, framework 20 and the gas flow detector 22 on the upside of framework 20.Described framework 20 is for the chip 23 on fixed plastics film 24 and plastic film 24 surface.Arrange heater (not shown) further in the hair-dryer 21 of downside, make hair-dryer blow out hot blast, the temperature of hot blast is can make it softening but not melt to be limited by heating of plastic film 24.Whether the gas flow detector 22 of upside can detect the air-flow at this place more than a setting threshold.Further, the gas flow detector 22 of upside comprises a siren 25, comprises Flexible Connector 26 further between plastic film 24 and framework 20.
Said apparatus can be used for spread sheet operation.The hair-dryer 21 of below can blow out hot blast, and plastic film 24 1 aspect occurs softening under the heating of hot blast, and one side receives hot blast blowing and being subject to a power upwards upwards.Can be there is arching upward upwards in plastic film 24, and then drive chip 23 to be separated under above-mentioned two conditions, realizes spread sheet.And whether the gas flow detector 22 on top breaks for detecting plastic film 24.If wind speed is excessive or heat overheated, plastic film 24 can be caused to break.Once plastic film 24 breaks, the wind of below just can blow to top, and then is detected by gas flow detector 22.Therefore arrange gas flow detector 22 to be found when plastic film 24 just breaks, and then stop blowing, control loss expands further.
Further, the gas flow detector of upside comprises a siren 25, and implements alarm operation when exceeding this threshold value, can operator be reminded the very first time to handle it.
Further, described framework 20 comprises further a Flexible Connector 26, for plastic film 24 and the frame body 20 of connection chip.Plastic film 24 is being increased by elasticity under heating state, and Flexible Connector 26 can drive plastic film 24 to extend to both sides, and then is conducive to chip 23 and is separated.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
