Described SMT tool, wherein, being positioned at 6 of described matrix central authorities described appearances material rooms is described second hold material room, and these 6 second are held each side having two adjacent one another are second and holding material room of material rooms.
Described SMT tool, wherein, the planar graph of described SMT tool is rectangle.
Described SMT tool, wherein, the described planar graph holding material room is rectangle.
Described SMT tool, wherein, described SMT tool employing flame resistant material grade is that the material of FR-4 is made.
Technique scheme tool has the following advantages or beneficial effect:
The appearance material room that SMT tool of the present utility model is arranged according to well-regulated arrayed by its surface, can make to treat that the materials and parts that paster operates are accommodated therein, and play the effect limiting its position, make materials and parts precisely can be adsorbed attachment by chip mounter in follow-up paster process, thus improve success rate and the operating efficiency of SMT; In addition owing to being provided with the appearance material room of the bottom lock of some in SMT tool of the present utility model, it can ensure that SMT tool can not be leaked vacuum by 100% in chip mounter, and the efficiency of adsorbing materials and parts is improved.
Accompanying drawing explanation
With reference to appended accompanying drawing, to describe embodiment of the present utility model more fully.But, appended accompanying drawing only for illustration of and elaboration, do not form the restriction to the utility model scope.
Fig. 1 is the structural representation of hopper of the prior art;
Fig. 2 is the structural representation of the SMT tool in the utility model embodiment;
Fig. 3 and Fig. 4 is the structure for amplifying schematic diagram of the SMT tool in the utility model embodiment.
Embodiment
The utility model provides a kind of SMT tool, and it can be used in the attachment process to semiconductor chip.
The profile of SMT tool of the present utility model is tabular, tool is provided with the appearance material room that several are matrix-style arrangement, hold material room at these and be divided into some first appearance material rooms and some second appearance material rooms, first bottom holding material room is provided with void region, the area of this void region is less than the aperture area of the first appearance material room, and the second bottom holding material room is then arranged for closing.
Fig. 2 illustrates the overall structure of the SMT tool in the utility model one embodiment, as shown in the figure, the profile of this SMT tool is tabular, namely its planar graph is a rectangle, be provided with several on the surface of this SMT tool and hold material room, place carry out follow-up attachment process for device to be processed, these hold the matrix arrangement of material room in rule, each holds material room and is provided with opening, can put into hold material room to make device to be processed from this opening part.
As shown in Figure 3 and Figure 4, the first difference part holding material room 2 and the second appearance material room 3 is that the bottom holding material room 2 first is also provided with void region 21, the area of this void region 21 should be less than the area of the opening of the first corresponding appearance material room 2, hold in material room 2 first to ensure that the device to be processed be placed into wherein can be mounted by this void region, thus play the effect of fixing device position to be processed.And void region is not set in the second bottom holding material room 3, but the closed setting in entity, this is the situation in order to avoid there is 100% leakage vacuum in patch device, to ensure normally carrying out of the follow-up paster operation of device to be processed.
The utility model one preferred embodiment in, these several the first size holding material room and the second appearance material room is set to identical, to meet the needs of regular matrix arrangement between making mutually, first holds material room and second holds the size of material room and quantity can need arrange according to for different device sizes.
In the utility model one preferred embodiment, some first appearance material rooms and some second hold material room and are arranged by the matrix being set to 9 × 12, namely 9 row 12 arrange, amount to 108, wherein, second to hold material room be 10, wherein six central position being distributed in this matrix, other four are distributed in the left and right sides of matrix with a component between two respectively, and this two group second is held material room respectively about matrix Central Symmetry.
In the above-described embodiments, as shown in Figures 2 and 3, the long a of rectangle SMT tool is set to 312.91mm, and wide b is set to 130.2mm, and high c is set to 5.6mm.And the side-play amount △ a that each row holds material room is 25.8mm, and the side-play amount △ b that every a line holds material room is 13.6mm.Wherein, the first long a1 holding the void region arranged in material room is 16.08mm, and its wide b1 is 6.6mm.Each cavity heights c1 holding material room is 3.35mm.
