Standard design and manufacturing that first frame 24, second frame 31, first flange 7 and second flange 8 are all formulated by solid state technology association (JEDEC).The profile of this pallet, the position of storage container 32 and density, the height of outside track, automation clamping, positioner profile and position all meet the regulation of JEDEC standard, therefore can satisfy stack arrangement.
In order to alleviate the weight of pallet to greatest extent; Save raw material and reduce cost; Can be with most pedestals 22 together with processing an octagon through hole with these pedestal 22 corresponding flat boards 6; This octagon through hole that the orientation is set is identical with the orientation of locator 25, this octagon through hole is to dig up pedestal 22 upper surfaces but do not influence the spacing muscle 23 of segmentation and be advisable; Do not process the octagon through hole but wherein have on six pedestals 22, form six vacuum storage containers, these six vacuum storage containers can be connected with vacuum equipment, are connected to pallet to allow vacuum equipment; Four centre positions that are in pallet in these six vacuum storage containers also have one near second frame 10, and last is near the 4th frame 12.The width of the spacing muscle 23 of segmentation is suitable according to the size of the LQFP encapsulated integrated circuit plastic-sealed body that pallet can hold.
During the single configuration of the utility model pallet:
1) with this pallet horizontal positioned, the opening that makes storage container 32 up.In each storage container 32, place a LQFP encapsulated integrated circuit; When placing this LQFP encapsulated integrated circuit: have the upside plastic-sealed body 3 of character to make progress printing; Pin 2 all around is downward; The end face of the downside plastic-sealed body 4 of LQFP encapsulated integrated circuit is close on the end face of pedestal 22, and is positioned at four zones that the spacing muscle 23 of segmentation surrounds on the pedestal 22, play the effect of fixed L QFP encapsulated integrated circuit in the horizontal direction; Simultaneously, four angles that the spacing muscle 23 of four segmentations that is not connected can prevent LQFP encapsulated integrated circuit plastic-sealed body in the transportation are stressed separately and wear and tear in the direction that is parallel to pedestal 22 end faces.
2) with this pallet horizontal positioned, the opening that makes storage container 32 down.In each locator 25, place a LQFP encapsulated integrated circuit; When placing this LQFP encapsulated integrated circuit: have the upside plastic-sealed body 3 of character downward printing; Pin 2 all around upwards; Make the end face of upside plastic-sealed body 3 be close to the end face of locator 25, and be positioned at the zone that four second spacing muscle 26 surround, locator 25 and four second spacing muscle 26 play the effect of fixed L QFP encapsulated integrated circuit in the horizontal direction.
When the LQFP encapsulated integrated circuit was put into pallet, first deep gouge 5 should be over against triangular part 15, so that the unified direction of packing into.
First flange 7 and second flange 8 have directivity, provide the obverse and reverse of pallet to represent.Outwards setovering in four first spacing muscle 21 tops in the same storage container 32, makes storage container 32 form uncovered structure, when this structure is packed pallet at the LQFP encapsulated integrated circuit, plays guide effect.Simultaneously; Behind the LQFP encapsulated integrated circuit of packing into; The first spacing muscle 21 plays fixation outside the pin 2 around the LQFP encapsulated integrated circuit; Prevent that the LQFP encapsulated integrated circuit from producing bigger the rocking of dull and stereotyped 6 directions that be parallel to, and abdicate the space for 32 4 jiaos, make things convenient for LQFP encapsulated integrated circuit " putting into " and " taking-up " to operate at all storage containers.
When a plurality of the utility model stackable pallets dispose:
Adjacent two pallets rely on the pattern draft combination of same slope; Realize accurate stack arrangement; One jiao of birds-eye perspective that dissects effect along the storage container diagonal of these two stackable pallets; Shown in figure 19, having demonstrated the LQFP encapsulated integrated circuit among the figure will stored space, the connected mode of gusset 28 and support column 29.Can know that by cutting plane pallet has more entity sectional area on storage container 32 diagonals, thereby improve the torsional resistance of pallet.Figure 20 is the section face upwarding view that gusset 28 is cut away in one jiao of cross section translation that forms along storage container 32 diagonal of two stackable pallets, has more intactly shown the storage container inner space.Shown in figure 21; Storage container 32 in the lower tray aligns with the locator 25 in the upper tray and forms complete storing containers; The LQFP encapsulated integrated circuit is supported and restriction in this storing containers; Four jiaos of the unsettled and plastic-sealed body of pin 2 do not stress in the horizontal direction all around, and four second spacing muscle 26 in the pallet of top on locator 25 end faces are used for bending towards an opposite side from pin 2, and promptly pin 2 exposes the LQFP encapsulated integrated circuit of fixed storage in this storing containers around the plastic-sealed body of side; Thereby make the pallet use of overturning, satisfy user demand more widely.The height of the height of the height of pedestal 22, the first structure muscle 20 height, the second structure muscle 34, the height of locator 25 and the second spacing muscle 26 has confirmed to pile up the height of the storing containers of formation jointly; Thereby the thickness direction at upside plastic-sealed body 3 and downside plastic-sealed body 4 has been fixed the LQFP encapsulated integrated circuit that places in the storing containers, guarantees that bigger rocking and turning on one's side can not take place in pallet the LQFP encapsulated integrated circuit.Simultaneously; Support column 29 in the upper tray just in time drops on the crosspoint of the lower tray first structure muscle 20 and the second structure muscle 34; Guarantee that pallet is dispersed in power on the structure of pallet itself when bearing certain pressure; And be unlikely to damage by pressure the LQFP encapsulated integrated circuit, in manufacturing process, support column 29 can be used as the stress point of demoulding push rod.
The foregoing description only is used for describing and explanation, offers those skilled in the art and realizes and use the utility model.Those skilled in the art can be under the situation that does not break away from the utility model thought; The skills and knowledge that relies on self; Embodiment is made all adjustment and variation; Thereby the protection range of the utility model all is not limited only to the foregoing description going up in all senses, and should be to meet the maximum magnitude that claims limit characteristic.
