Empty channel status, during components and parts on a printed circuit, makes the components and parts can be at printed circuit by vac sorb
During remain fixed in the state on printed circuit board (PCB).
In order to make more firm being connected with printer of whole SMT Vacuum printing tool, it is ensured that SMT Vacuum printing tool
Sufficiently stable.
The non-hollow part on the downside of fixed layer 1 that the present embodiment provides is evenly arranged with multiple Magnet 13.
By above example it can be seen that the non-hollow part on the downside of fixed layer 1 is evenly arranged with multiple Magnet 13, if
The multiple Magnet 13 put mainly make to install strong magnetic and printer platform tightly phase bottom the fixed layer 1 of SMT Vacuum printing tool
Inhale, make SMT Vacuum printing tool inhale in printer platform entirely without gap, thereby may be ensured that high-accuracy element print tin cream
Time first-pass yield reach 99.9% and the high-precision printing tool that designs.
In order to ensure the bonding strength that SMT Vacuum printing tool is connected with printer, the Magnet that the present embodiment proposes is
Strong magnets.The Magnet 13 that the present embodiment provides is strong magnets.
By above example it can be seen that the bottom of fixed layer 3 non-hollow is provided with Magnet 13, and this Magnet 13 is strong
Power Magnet, strong magnets is primarily to be that fixed layer is connected with printer platform more securely, it is ensured that absorption affinity, thus protects
Demand during card precision components print solder paste.
In order to ensure that whole SMT Vacuum printing tool forms the space of an evacuation so that vacuum hole and inlet scoop it
Between realize realizing effectively connecting and can guarantee that holding vacuum in whole printing process, reach to make printed circuit board (PCB) tight
Close absorption purpose on SMT Vacuum printing tool.
The middle part in intermediate layer that the present embodiment provides offers opening, is provided around perforate at opening.
By above example it can be seen that the middle part in intermediate layer 2 offers opening, being provided around out of opening
Hole.The setting of the opening in intermediate layer 2 mainly makes whole SMT Vacuum printing tool form the path of an evacuation, it is ensured that true
The trouble-free operation of do-nothing system；The perforate being arranged around at opening is to play connection printing layer 3 and intermediate layer 2 and intermediate layer 2 with solid
The effect of given layer 1.
In order to make together with printing layer is more securely attached to fixed layer.The printing layer 3 of the present embodiment offer, intermediate layer
2 and fixed layer 1 be equipped with multiple screw hole 4.
By above example it can be seen that printing layer 3, intermediate layer 2 and fixed layer 1 are equipped with multiple screw hole 4, screw
The setting in hole 4 mainly makes together with printing layer 3, intermediate layer 2 be more securely attached to fixed layer 1 by screw, it is ensured that print
Bonding strength between brush layer 3, intermediate layer 2 and fixed layer 1.
In order to make the vacuum system of SMT Vacuum printing tool be connected with the vacuum interface of printer.The present embodiment provides
The outside of inlet scoop 8 is provided with iron hoop 9.
By above example it can be seen that the outside of inlet scoop 8 is provided with iron hoop 9, the setting of this iron hoop 9 is mainly
The effect being connected with the vacuum interface of printer to the vacuum system being SMT Vacuum printing tool, it is ensured that whole vacuum system
For path, the operation of evacuation can be smoothed out.
