Shown in Fig. 7 to Fig. 9 is common; The width of first small opening 13 is consistent with the width of first opposite side 321; Width between every group first small opening 13 equals two first width between the opposite side 321, and the length of first small opening 13 is the width L3 that the length L 1 of first opposite side deducts two second opposite side; The width of second small opening 4 is consistent with the width of second opposite side 322, and the width between every group second small opening 4 equals two second width between the opposite side 322, and the length of second small opening 4 is the length L 2 of second opposite side.
In addition, first scraper 2 and second scraper all tilt to install, and the angle between the brush cream direction can better produce the effect of an extruding greater than 60 ° and less than 90 ° to tin cream.
Shown in Fig. 6-9; The brush cream technique that uses above-mentioned device to carry out; Pending to as if the integrated pcb board of some monomer silicon microphones 3; Each monomer silicon microphone 3 has mounted microchips 31 such as MEMS on it, and the Copper Foil 32 at each monomer silicon microphone 3 edge has two first relative opposite side 321 and two second relative opposite side 322.The final purpose of this technological process is all to coat the tin cream of the uniform thickness of according with process requirements on the Copper Foil 32 with monomer silicon microphone 3 edges all on the pcb board.
This brush cream technique may further comprise the steps:
A. produce the first tri-dimensional screen 1+, first scraper 2 and second tri-dimensional screen+second scraper that is complementary according to the related data and the technological requirement that are integrated with the pcb board of some monomer silicon microphones 3; Wherein, the thickness of the first web plate body 11 and the second web plate body equals the tin cream thickness at the monomer silicon microphone edge of technological requirement.First tri-dimensional screen 1 and first scraper 2 are installed on first stencil printer, second tri-dimensional screen and second scraper are installed on second stencil printer;
The pcb board that b. will be integrated with some monomer silicon microphones 3 is positioned on the conveyer belt of first stencil printer, is sent to the below of first tri-dimensional screen 1, and first tri-dimensional screen 1 descends, and compresses pcb board; The microchip 31 that mounts on the monomer silicon microphone 3 is placed in first protective cover 12, and every group first small opening 13 is corresponding one by one with two first opposite side 321 of the Copper Foil 32 at each monomer silicon microphone 3 edge, and first small opening 13 overlaps with the center line of first opposite side 321; First scraper 2 descends then, and first groove 21 plugs together with first protective cover 12 mutually, and the bottom margin of first scraper 2 closely pastes with the upper surface of first tri-dimensional screen 1 mutually; First scraper 2 moves along the bearing of trend of first protective cover 12 then; To be extruded into opposite side from a thruster attached to the tin cream of first tri-dimensional screen, 1 upper surface; Tin cream is attached to by first small opening 13 on two first opposite side 321 of Copper Foil 32 at monomer silicon microphone 3 edges, accomplishes the brush cream operation of first opposite side 321.Because the bottom margin of first scraper 2 closely pastes with the upper surface of first tri-dimensional screen 1 mutually; Like this; When the bearing of trend of first scraper 2 along first protective cover 12 moves; Tin cream has guaranteed the more effective realization of brush cream process not drained to another side from the one side of scraper all the time by in the process of pushing.
In the process of above-mentioned brush cream operation; Because the length of first small opening 13 is the width L3 that the length L 1 of first opposite side deducts two second opposite side; And first small opening 13 overlaps with the center line of first opposite side 321; Therefore, first small opening 13 can not cover four bights of the tinfoil paper at monomer silicon microphone 3 edges, and the part of promptly only two first opposite side 321 being removed two bights is brushed cream.
C. the pcb board that will accomplish the operation of first opposite side brush cream is positioned on the conveyer belt of second stencil printer, is sent to the below of second tri-dimensional screen, and second tri-dimensional screen descends, and compresses pcb board; The microchip 31 that mounts on the monomer silicon microphone 3 is placed in second protective cover, and every group second small opening 4 is corresponding one by one with two second opposite side 322 of the Copper Foil 32 at each monomer silicon microphone 3 edge; Second scraper descends then, and second groove plugs together with second protective cover mutually, and the bottom margin of second scraper closely pastes with the upper surface of second tri-dimensional screen mutually; Second scraper moves along the bearing of trend of second protective cover then, will be extruded into opposite side from a thruster attached to the tin cream of the second tri-dimensional screen upper surface, and tin cream is attached to by second small opening 4 on two second opposite side 322 of Copper Foil 32 at monomer silicon microphone 3 edges.Because the length of second small opening 4 is the length of second opposite side 322, so be that whole second opposite side 322 is brushed cream, finally makes the tin cream that all is coated with the uniform thickness of according with process requirements on the whole copper foil 32, accomplish brush cream process.
