Description
Technical field
The utility model is related to manufacture printed circuit technique field, in particular to a kind of new SMT screen plate.
Background technology
Web plate stencil, also known as silk screen, steel mesh；For paste solder printing, the base of SMT surface mounting technology industry indispensabilities
Plinth articles for use, by paste solder printing on PCB printed circuit board (PCB), so as to carry out patch and solder reflow weldering.Currently, SMT assembly lines are set
It is standby to have strict demand to the thickness of web plate, and existing SMT equipment cannot voluntarily be adjusted according to web plate thickness.Each producer's manufacture
Equipment web plate thickness requirement is slightly different.Therefore, for some large enterprises, storing hundreds and thousands of blocks of web plates needs largely
Memory space can cause being significantly increased for maintenance cost.In addition, each web plate must reach certain thickness, it can also increase and cause
The cost of web plate, in the prior art, printed steel mesh thickness are single, when carrying out paste solder printing, can not meet all pads simultaneously
On the requirement of tin amount, after welding, easily occur to lack tin amount at the component's feet of part missing solder or tin amount is caused to cause short circuit too much
The problems such as.
Utility model content
The purpose of this utility model is to solve existing issue and one kind for proposing can replace different-thickness, is met not
The new SMT screen plate needed with printing.
In order to solve the above technical problems, technical solution provided by the utility model is：A kind of new SMT screen plate, including outer
Frame cures circle and printed steel plate, it is characterised in that：The printed steel plate is equipped with several printing holes, the printed steel plate week
It encloses equipped with the fixed frame for fixing printing steel plate, the printed steel plate is detachable connection structure with fixed frame, described solid
Determine frame and be connected by curing circle with outline border, be equipped on described four apex angles of fixed frame and detain angle, between the adjacent button angle of each two
Shaft is equipped with, the shaft is equipped with the fixed plate for fixing printing steel plate.
The utility model has the following advantages that compared with prior art：The utility model device replaces difference with easy to disassemble
The printed steel plate of thickness meets a variety of print requests, preferably control printing tin amount, reduces missing solder or tin amount causes short circuit too much
The problems such as, improve product yield.
Preferably, curing agent used in the curing circle is epoxy resin, preferably protects entire web plate.
Preferably, the fixed plate is equipped with knob easy to disassemble, printed steel plate easy to disassemble.
Preferably, the fixed plate both ends are equipped with the sponge that printed steel plate is protected not to be scratched close to printed steel plate one side
Pad, the protection printed steel plate of replacement improve service life.
Description of the drawings
Fig. 1 is a kind of structure diagram of new SMT screen plate of the utility model.
Fig. 2 is a kind of structure diagram of the fixed plate of new SMT screen plate of the utility model.
As shown in the figure：1st, outline border, 2, cure circle, 3, printed steel plate, 4, printing hole, 5, fixed frame, 6, button angle, 7, shaft,

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
With reference to attached drawing, a kind of new SMT screen plate including outline border 1, cures circle 2 and printed steel plate 3, it is characterised in that：It is described
Printed steel plate 3 is equipped with several printing holes 4, and the fixed frame 5 for fixing printing steel plate 3 is equipped with around the printed steel plate 3,
The printed steel plate 3 is detachable connection structure with fixed frame 5, and the fixed frame 5 is connected by curing circle 2 with outline border 1, institute
It states and button angle 6 is equipped on 5 four apex angles of fixed frame, be equipped with shaft 7 between the adjacent button angle 6 of each two, set in the shaft 7
It is useful for the fixed plate 8 of fixing printing steel plate 3.
Curing agent used in the curing circle 2 is epoxy resin.
The fixed plate 8 is equipped with knob 9 easy to disassemble.
8 both ends of fixed plate are equipped with the foam-rubber cushion 10 that printed steel plate 3 is protected not to be scratched close to 3 one side of printed steel plate.
Be arranged fixed frame in the utility model outline border, fixed frame is internally provided with dismountable printed steel plate, fixed frame with it is outer
Pass through epoxy resin cure between frame, it is ensured that the sound construction of whole device is printed by the printing hole on printed steel plate
Brush, shaft are arranged on two adjacent button angles, and by pulling the knob in fixed plate, fixed plate turns under the drive of shaft
It is dynamic, realize the removable unloading functions to printed steel plate, the foam-rubber cushion of fixed plate end can be prevented from scratching printed steel plate, made to extend
Use the service life.
The utility model and embodiments thereof are described above, this description is no restricted, shown in attached drawing
Be also the utility model one of embodiment, actual structure is not limited thereto.All in all if this field
Those of ordinary skill is enlightened by it, without deviating from the purpose of the present invention, not inventively design with
The similar frame mode of the technical solution and embodiment, all should belong to the protection range of the utility model.
