Description
Technical field
The utility model is related to electronic manufacture assembling field, more particularly to a kind of clad steel with fixed plate bit function
Net.
Background technology
Steel mesh (Stencils) namely SMT templates (SMT Stencil), are a kind of SMT particular manufacturing crafts；Its major function
It is to aid in the deposition of tin cream；Purpose is the accurate location being transferred to the tin cream of accurate quantity on sky PCB.Steel mesh is initially by silk
What net was made, therefore web plate (mask) is at that time.With SMT development, web plate requirement is increased, steel mesh is just produced therewith.
Influenceed by material cost and the difficulty or ease program of making, initial steel mesh is made up of iron/copper coin, but also in that easy-to-rust,
Stainless steel steel mesh just instead of them, that is, present steel mesh (SMT Stencil).
Generally, module producer is required for allowing pcb board by steel mesh with the side of brush tin cream before PCBA semi-finished product are made
Formula, makes hole position of the tin cream by steel mesh, be attached on PCB has PAD exactly（Pad）Place.And current pcb board factory
The SMT printed steel mesh that family is provided, is only merely one layer of stainless steel steel mesh with hole position, and sample preparation personnel place below steel mesh
After good sky PCB, a relative position agreed with substantially can be only achieved by adjustment for several times, will so greatly reduce sample preparation
The sample preparation efficiency of personnel.Therefore, steel mesh is difficult to the defect aligned, becomes anxious to be resolved one of those skilled in the art and asks
Topic.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art that there is provided a kind of rapid-aligning, time-saving tool
There is the compound steel mesh of fixed plate bit function.
The technical solution of the utility model is：A kind of compound steel mesh with fixed plate bit function, it is characterised in that：Including
Two layers of steel mesh, is divided into upper strata steel mesh and lower floor's steel mesh；Described upper strata steel mesh one end, which is provided with the middle of groove, upper strata steel mesh, is provided with PAD
Hole position；Described lower floor's steel mesh one end, which is provided with to be provided with the middle of protruding block, lower floor's steel mesh, hollows out groove；The groove of the upper strata steel mesh is with
The protruding block of layer steel mesh, which cooperates, to be connected.
Further, the protruding block of lower floor's steel mesh has magnetic, makes upper strata steel mesh and lower floor's steel mesh tight by magnetic
It is closely connected to close.
Further, it is mutually corresponding provided with PAD hole positions and the PAD positions on the PCB assembled in the middle of the upper strata steel mesh.
Further, the shape that groove is hollowed out described in lower floor's steel mesh centre is identical with the PCB shapes assembled.
The beneficial effects of the utility model are：The utility model has a compound steel mesh of fixed plate bit function, ingenious in design,
It is simple to operate, it tin cream is attached to by the hole position of steel mesh on the PAD of pcb board, save the time, improve
Production efficiency, the structure that solves printed steel mesh in the prior art is too single, and technical staff can not be high in use
Effect contraposition PCB, causes the technical problem of sample preparation inefficiency.

Fig. 3 is lower floor's steel mesh schematic diagram.
Reference：Upper strata steel mesh 1, lower floor's steel mesh 2, groove 3, PAD hole positions 4, protruding block 5, hollow out groove 6.
Embodiment
Implementation structure of the present utility model is described below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, the utility model has the compound steel mesh of fixed plate bit function, including two layers of steel mesh, is divided into
Upper strata steel mesh 1 and lower floor's steel mesh 2；The one end of upper strata steel mesh 1 is provided with the middle of groove 3, upper strata steel mesh 1 and is provided with PAD hole positions 4；Lower floor's steel
The one end of net 2 is provided with having magnetic protruding block 5, and the centre of lower floor's steel mesh 2, which is provided with, hollows out groove 6；The groove 3 of upper strata steel mesh 1 and lower floor
The protruding block 5 of steel mesh 2, which cooperates, to be connected.
Preferably, it is mutually corresponding provided with PAD hole positions 4 and the PAD positions on the PCB assembled in the middle of upper strata steel mesh 1.
Preferably, the shape that groove 6 is hollowed out described in the centre of lower floor's steel mesh 2 is identical with the PCB shapes assembled.
The use step that the utility model has the compound steel mesh of fixed plate bit function includes：1. it is, first that lower floor's steel mesh 2 is flat
Desktop is placed in, has one end of protruding block 5 upward；2. and then by PCB put into and hollow out groove 6, PCB PAD is face-up；3., by upper strata
The groove 3 of steel mesh 1 is fitted with the protruding block 5 of lower floor steel mesh 2 by magnetic compact, while being provided with PAD hole positions in the middle of upper strata steel mesh 1
4 is mutually corresponding with the PAD positions on the PCB assembled, is quick and precisely aligned so as to realize, the one end of lower floor's steel mesh 2 is provided with protruding block 5
With compared with ferromagnetism, it is ensured that two layers of steel mesh is precisely brought into close contact by magnetic up and down, efficient rapid-aligning is realized, and be not free
Gap, the phenomenon such as rock, shift and occur.
It is described above, embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change expected without creative work or simple replacement should all be covered in protection model of the present utility model
Within enclosing.
