Each flexible member 5 all has a court and extends away from this base plate 3 direction and can the bullet of elastics wing Property rod 51 (or claiming elastic rod) and one be positioned at flexible rod 51 away from one end of base plate 3 be bent to form curved Folding part 52.In the present embodiment, the flexible rod 51 of each flexible member 5 is overall with kink 52 L-shaped. Flexible rod 51 can be formed in one with base plate 3 and be connected, and the flexible rod 51 section in parallel mat 3 direction is square Shape.
After the plurality of first structure 2 mutually assembles and constitutes this carrier 11, as shown in Fig. 6 top view, respectively should The base plate 3 of the first structure 2 cooperates and constitutes a slightly plate body in tetragon, and this plate body has four angles Falling 31, be decrescence the closer to spacing d between the flexible member 5 at corner 31, this design is available for wafer and is blown Stroke and during separating floating, wafer and the position of collision of surrounding elastomeric element 5 often occur at corner 31, because of When this spacing that will be close to the flexible member 5 at corner 31 reduces or arranges the most intensive, increase stress Contact area, is conducive to relaxing the collision problem of Waffer edge corner.
Refering to Fig. 4,7,8, the present embodiment is on using, and the bearing space 110 of this base board carrier 1 is used for Containing multiple wafer 8,8 ', base board carrier 1 is placed on a feeder, and feeder is solaode Manufacture process is used for carrying the machine of wafer 8,8 ', and feeder comprises two difference and can spray gas Blow gun 71, one can wear this base board carrier 1 and the lifting apparatus that wafer 8 can be made to increase up or down 72 and one can draw wafer 8,8 ' and wafer 8,8 ' is positioned in a conveyer belt (not shown) Handling device 73.Wherein, this lifting apparatus 72 makes wafer 8 be positioned at the height of two blow guns 71, and leads to Cross blow gun 71 to blow and make the wafer 8 ' of top separated from one another, then draw the wafer of the top with Handling device 73 8 ' to complete the action of pickup.
When the wafer 8 ' of aforementioned top is separated from one another because being brushed by air-flow, easily because of gas flow-disturbing, left and right is shaken Move and touch the flexible member 5 of surrounding, but after life-time service, if the flexible rod 51 of flexible member 5 is subject to The cutting at wafer 8 ' edge and form indentation, chase is when even rupturing, the flexible member 5 of visual consume is Belong to which the first structure 2, more immediately replace this first structure 2 having damage, to avoid The problem directly replacing whole base board carrier 1 such as traditional mode and have high cost.
It addition, in the present embodiment, the flexible rod 51 of each flexible member 5 is in the width near kink 52 The width spending closer base plate 3 is little, promotes the elasticity at flexible member 5 adjacent top end whereby.In other words Say, by the design of this from bottom to top width decrescence (or title girth is the least), the whole of flexible rod 51 can be made Body reaches optimal collocation between structural strength and elasticity, therefrom can promote the elasticity of flexible rod 51 again Abut effect.And above-mentioned kink 52 is to be formed towards deviating from this bearing space 110 direction.
It addition, on implementing, flexible member 5 i.e. bends away from this base plate 3 at the end of its flexible rod 51 Forming this kink 52, thus can strengthen the structural strength at place above flexible rod 51, such design also may be used Design with above-mentioned flexible rod 51 width decrescence (or title girth is the least) is arranged in pairs or groups mutually.
In the present embodiment, flexible rod 51 is formed in one with base plate 3.On other embodiments, bullet The flexible rod 51 of property element 5 can be adopted the mode of plugging and is fixed on base plate 3.Now, the elasticity of flexible member 5 Rod 51 sections in this base plate 3 direction parallel are that the design of non-circular such as rectangle is preferred.If this is because of elastic When rod 51 is circular, base plate 3 hole of its corresponding inserted also needs circle, the most easily makes flexible rod 51 in it Middle generation rotates, and then makes the kink 52 being originally intended to arrange outwardly transfer inwardly, so generation to be picked and placeed Even the inconvenience of sheet causes the shock of wafer 8,8 ' to rupture.
Refering to Fig. 6,7,8, in the present embodiment, the flexible member 5 section in parallel mat 3 direction in Rectangle, the flexible rod 51 of flexible member 5 have one towards bearing space 110 and be available for wafer 8,8 ' against Surface 511, by these surfaces 511 with the form in face for wafer 8,8 ' edge against, both contacts area Can lower and touch impulsive force relatively greatly, to avoid wafer 8,8 ' to produce fragmentation or the surface 511 of flexible rod 51 Produce the problems such as damage.
In the present embodiment, spacing d between flexible member 5 at corner 31 is decrescence, this design Being available for wafer 8 ' to be brushed and during separating floating, wafer 8 ' often occurs with the position of collision of surrounding elastomeric element 5 At corner 31, spacing d that therefore will be close to the flexible member 5 at corner 31 reduces or arranges the most intensive Time, increase the contact area of stress, be conducive to relaxing the collision problem at wafer 8 ' edge corner.
Refering to Fig. 4,5,8, by above design, the use longevity of the carrier 11 of base board carrier 1 can be improved Life, if but long-time use lower and time still there is abrasion, fracture in flexible member 5, flexible member 5 can be damaged That bad first structure 2 is replaced, in order to avoid make wafer 8,8 ' by flexible member 5 because not changing Impact and rupture.
