Abstract
The utility model provides a printing template that position was kept away to PCB sheet metal finger, it sets up the position to be equipped with a plurality of components on the PCB board and to have the golden finger, seted up a plurality of through -holes in the printing template, this through -hole corresponds the component position is seted up on the PCB board, its characterized in that: correspond in the printing template golden finger on the PCB board sets up the groove of keeping away that the position was equipped with an indent, and the groove depth that should keep away a groove is not less than the golden finger protrusion in the height on PCB board surface. The utility model discloses a golden finger correspond the PCB board in the printing template on sets up the groove of keeping away that the position set up an indent to the golden finger touches the bottom of printing the template when preventing to print, and borrow this design to cancel and prevent welding glue, with the purpose that reaches saving manufacturing cost and human cost, and can not be influenced to the quality of product. Compared with the prior art, the utility model has the advantages of simple structure, the effect is showing, by a wide margin reduce cost.
Description
Technical field
The utility model relates to SMT, i.e. the surface mounting technology field of pcb board, and what be specifically related to use in a kind of printing process has the printing stencil that pcb board golden finger keeps away bit function.
Background technology
Pcb board surface mounting technology (being called for short SMT) generally includes the several operation of pasting board, printing, piece and Reflow Soldering.Wherein, printing process is that tin cream (SolderPaste) is printed by the through hole on printing stencil (Stencil, industry is also known as steel mesh, steel plate or web plate) operation be placed on pcb board, and on the corresponding pcb board to be printed of described through hole, position of components is offered.As can be seen here, described printing stencil plays very important role in printing process.
Due to pcb board being equipped with golden finger, and a lot of golden finger position is set all at the upper surface of pcb board, in production way, have tin sticky bad in order to preventing golden finger, this golden finger position all can post anti-welding glue and prints before manufacture, if do not post anti-welding glue, when printing, the golden finger of described pcb board will be close to the bottom of printing stencil, what glass putty residual bottom printing stencil and tin cream will be bonded at golden finger arranges position, the bad problem of tin sticky is just there will be after melting down, tin sticky is many cannot keep in repair golden finger position will be caused cannot to bind to cause and scrap, and then increase production cost, the golden finger of pcb board pastes anti-welding glue and then can increase production cost and human cost simultaneously.
For this reason, how to solve the deficiency that above-mentioned prior art exists, just become the problem that the utility model will be studied.
Summary of the invention
The utility model provides a kind of pcb board golden finger to keep away the printing stencil of position, its object is to solve prior art on the golden finger of pcb board, pastes the problem that anti-welding glue can increase production cost and human cost.
For achieving the above object, the technical solution adopted in the utility model is: a kind of pcb board golden finger keeps away the printing stencil of position, and described pcb board is provided with some elements and has golden finger and arranges position; Described printing stencil offers some through holes, and on the corresponding described pcb board of this through hole, position of components is offered; Wherein, the golden finger on described printing stencil on corresponding described pcb board arranges the bit-avoiding slot that position is provided with an indent, and the groove depth of this bit-avoiding slot is not less than the height that described golden finger protrudes from described pcb board surface.
Related content in technique scheme is explained as follows:
1., in such scheme, when the bit-avoiding slot of described indent can prevent from printing, golden finger touches the bottom of printing stencil.
Operation principle of the present utility model and advantage as follows:
A kind of pcb board golden finger keeps away the printing stencil of position, by the golden finger on pcb board corresponding on printing stencil, the bit-avoiding slot that position arranges an indent is set, during to prevent from printing, golden finger touches the bottom of printing stencil, design can cancel anti-welding glue whereby, to reach the object saved production cost with human cost, and can not be influenced to the quality of product.Compared to existing technologies, it is simple that the utility model has structure, Be very effective, the advantage that can significantly reduce costs.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the utility model embodiment.
In above accompanying drawing: 1. printing stencil; 2. through hole; 3. bit-avoiding slot.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment: shown in accompanying drawing 1, a kind of pcb board golden finger keeps away the printing stencil 1 of position, and described pcb board is provided with some elements and has golden finger and arranges position; Described printing stencil 1 offers some through holes 2, and on the corresponding described pcb board of this through hole 2, position of components is offered; Wherein, the golden finger on described printing stencil 1 on corresponding described pcb board arranges the bit-avoiding slot 3 that position is provided with an indent, and the groove depth of this bit-avoiding slot 3 is not less than the height that described golden finger protrudes from described pcb board surface.
The utility model arranges by the golden finger on pcb board corresponding on printing stencil the bit-avoiding slot that position arranges an indent, during to prevent from printing, golden finger touches the bottom of printing stencil, design can cancel anti-welding glue whereby, to reach the object saved production cost with human cost, and can not be influenced to the quality of product.Compared to existing technologies, it is simple that the utility model has structure, Be very effective, the advantage that can significantly reduce costs.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection range of the present utility model.
Claims (1)
1. pcb board golden finger keeps away a printing stencil for position, and described pcb board is provided with some elements and has golden finger and arranges position; Described printing stencil offers some through holes, and on the corresponding described pcb board of this through hole, position of components is offered; It is characterized in that: the golden finger on described printing stencil on corresponding described pcb board arranges the bit-avoiding slot that position is provided with an indent, the groove depth of this bit-avoiding slot is not less than the height that described golden finger protrudes from described pcb board surface.
