Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
In existing MEMS pressure sensor encapsulation process shown in Fig. 1, need the annulus 1 made with plastics or metal material to paste on a substrate 2.Owing to market there is no special annulus attaching apparatus, generally all adopt and paste manually.Uncontrollable factor when pasting because artificial is too many, repeatability and uniformity is too poor, efficiency is low, human cost comparatively greatly, be difficult to realize mass production.And in manual taping process, easily touch MEMS chip and bonding wire, affect the quality of packaging part.In order to solve problems of the prior art, the utility model provides a kind of structure annulus pasting mould as shown in Figure 2, can not only enhance productivity, and can avoid the touching to MEMS chip and bonding wire, ensures packaging part quality.This annulus pasting mould comprises lower bolster 5, gripper shoe 4 and cope match-plate pattern 3 and forms; Lower bolster 5 as shown in Figure 3, comprises the lower bolster plate body 7 of tabular, and a face of lower bolster plate body 7 is provided with multiple columniform projection 8, and the rectangular array of the plurality of projection 8 is arranged; Gripper shoe 4 as shown in Figure 4, comprises the gripper shoe plate body 9 of tabular, and the first working hole 10, first working hole 10 that gripper shoe plate body 9 is provided with quantity identical with projection 8 quantity is stepped hole; The end face that first working hole 10 corresponds to the gripper shoe plate body 9 at the place, hole that diameter is larger in projection 8, first working hole 10 to be provided with at least two pilot pins 6, first working hole 10 diameter compared with the aperture of aperture and the diameter of projection 8 suitable; Cope match-plate pattern 3 as shown in Figure 5, comprise the cope match-plate pattern plate body 11 of tabular, cope match-plate pattern plate body 11 is processed with the second working hole 12 that quantity is identical with projection 8 quantity, second working hole 12 is corresponding with a projection 8, the diameter of the second working hole 12 is identical compared with the diameter of macropore with diameter in the first working hole 10, and cope match-plate pattern plate body 11 is processed with the locating hole 13 identical with pilot pin 6 quantity.Cope match-plate pattern 3, gripper shoe 4 and lower bolster 5 are assembled into the annulus pasting mould as Fig. 2: by hole less for diameter in the first working hole 10 towards lower bolster 5, gripper shoe 4 is placed on lower bolster 5, make each projection 8 through the first working hole 10 corresponding thereto, each projection 8 and this projection 8 through the first working hole 10 in form the groove 14 of annular the larger hole of diameter, as shown in Figure 6; Then cope match-plate pattern 3 is positioned in gripper shoe 4, pilot pin 6 penetrates locating hole 13, position between cope match-plate pattern 3 and gripper shoe 4 is fixed, each projection 8 penetrates in the second working hole 12 corresponding thereto, the end face of projection 8 is mutually concordant with the upper surface of cope match-plate pattern 3, second working hole 12 is connected with groove 14 with the annular space between projection 8, and form mounting groove 16, the degree of depth of mounting groove 16 is identical with the height of annulus 1.
In the diameter of the second working hole 12 and the first working hole 10, diameter is all suitable with the external diameter of annulus 1 compared with the diameter of macropore, and in the diameter of projection 8 and the first working hole 10, diameter is all suitable with the internal diameter of annulus 1 compared with the diameter of aperture.
Gripper shoe 4 adopts exotic material, as metal or alloy material is made; Cope match-plate pattern 3 and lower bolster 5 adopt metal material to make; The requirement such as precision, deformation, durability that gripper shoe 4, cope match-plate pattern 3 and lower bolster 5 demand fulfillment mould use.
The utility model annulus pasting mould is adopted to paste the method for MEMS pressure sensor annulus:
Step 1: annulus 1 is positioned in mounting groove, the upper surface of annulus 1 top and cope match-plate pattern 3 maintains an equal level, and as shown in Figure 7, then applies one deck colloid at annulus 1 end face, forms encapsulating glue-line 15, completes the brush coating of annulus 1; The end face of projection 8 is mutually concordant with the upper surface of cope match-plate pattern 3, glue can be prevented to the flowing of planar recess region and converge, keeping the consistency of thickness of encapsulating glue-line 15, improve the efficiency of brush coating.
Step 2: after brush coating completes, removes cope match-plate pattern 3 and lower bolster 5, only leaves gripper shoe 4 and annulus 1;
Step 3: by substrate 2 left-hand thread on annulus 1, substrate 2 is located by pilot pin 6 and gripper shoe 4, and annulus 1 is pasted with substrate 2 by encapsulating glue-line 15, as shown in Figure 8, completes annulus and pastes;
Step 4: gripper shoe 4, substrate 2 are sent into baking oven after pasting by annulus 1 together with annulus 1, toasts 3 hours at the temperature of 140 DEG C, after encapsulating glue-line 15 solidifies, gripper shoe 4 is separated with the substrate 2 being pasted with annulus 1, completes the stickup of annulus 1.
A projection corresponding in the utility model annulus pasting mould 8, first working hole 10 and second working hole 12 form a working cell, and this working cell may correspond to the stickup of an annulus 1.Compared to pasting manually, this mold use can save cost of labor in a large number, reduce the waste of artificial uncontrollable factor and encapsulating compound, and the situation touching spun gold in manual taping process can be avoided to occur, effectively promote the quality of operating efficiency and annulus stickup.
