Abstract
The invention discloses a spacer used for silk screen of a printed circuit board. The spacer comprises a spacer body (1) and is characterized in that pins (2) used for fixing and supporting the PCB and ejector nails (3) used for supporting the PCB in an auxiliary mode are arranged on the spacer body (1), the pins (2) are located on the four corners of the PCB, and the ejector nails (3) are arranged at the position, corresponding to the position where a window needs to be opened on the PCB for formation, of the spacer body. The spacer used for silk screen of the PCB is low in manufacturing cost, the production efficiency and the silk screen effect can be improved.
Description
Technical field
The present invention relates to field of printed circuit board fabrication, relate in particular to a kind of printed circuit board (PCB) silk-screen pad.
Background technology
In circuit board fabrication industry, anti-welding operation (printing the green paint of welding resistance) is absolutely necessary,, it is mainly used to separate assembling district and non-assembling district reaches the object that blocks scolding tin.In industry, for the green paint of welding resistance anti-welding effect and functional aspect there is quite rigorous requirement, as: electrical properties (dielectric strength, dielectric constant, moisture-proof gas insulation resistance), flame resistance, chemical resistance etc., the anti-welding operation production procedure of circuit board is also relatively long simultaneously.Along with the development of technology, traditionally in anti-welding operation be printed on one side, the pre-bake mode of one side cannot meet quality and the requirement of the phase of friendship, has not only increased the unnecessary ，Shi enterprise production cost of scrapping and has improved, and also makes enterprises production efficiency be subject to certain restrictions.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of cost of manufacture low, the printed circuit board (PCB) silk-screen pad of production efficiency and printing effect can be provided.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of printed circuit board (PCB) silk-screen pad, comprise lamellar body, described lamellar body is provided with for the pin of fixing and supporting printing board and for the top of supplemental support printed circuit board (PCB) and follows closely, described pin is positioned at four jiaos of printed circuit board (PCB)s, and top nail is arranged at lamellar body with on printed circuit board (PCB) need be windowed, moulding place is corresponding position.
Described pin comprises a square substrate, and one jiao of square substrate arranges fixed body, and fixed body two ends penetrate square substrate; Corresponding, fixing hole is set on lamellar body, fixed body one end of pin is fixed in fixing hole, and the square substrate of pin adopts sticking double faced adhesive tape on lamellar body.
Described top nail comprises a substrate, and the riveting of substrate one side has supporter, and the substrate of top nail adopts sticking double faced adhesive tape on lamellar body.
The position boring of the corresponding pad pin of printed circuit board (PCB) periphery, during use, is placed in printed circuit board (PCB) the pin fixed body upper end of described pad, is placed on and on printing machine platform, completes ink printing.
Compared with prior art, the beneficial effect that the present invention has is:
While utilizing silk-screen of the present invention, printed circuit board (PCB) can be erected, be convenient to printed circuit board (PCB) and use a screen printer simultaneously to finish printing end blocking printing another side, after printed on both sides, two sides can disposablely complete pre-baked, effectively improving production efficiency and economizing on resources; On the other hand, printed circuit board (PCB) is erected, its upper and lower circulation of air is better, during ink for screen printing, is convenient to ink and fully immerses, and particularly for some via holes, whole silk-screen is effective.
The present invention is simple for structure, easy to make, with low cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of pad for a kind of printed circuit board (PCB) silk-screen of the present invention;
Accompanying drawing 2 is pin feature schematic diagrames of pad for a kind of printed circuit board (PCB) silk-screen;
Fig. 3 is the top pin structure schematic diagram of pad for a kind of printed circuit board (PCB) silk-screen.
In figure, be labeled as: lamellar body 1, fixing hole 10, pin 2, substrate 21, fixed body 22, top nail 3, connecting portion 31, supporter 32.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Pin and top nail are two kinds of staples that this area is more often used.As Fig. 2, pin is comprised of a square substrate 21 and fixed body 22, and fixed body 22 two ends penetrate square substrate 21, and fixed body 22 two ends all can be used for supporting or be fixing.
As Fig. 3, top nail is comprised of substrate 31 and supporter 32, and top nail substrate is for fixing, and supporter 32 is positioned at substrate one side, and therefore top nail has one direction supporting role.
As Fig. 1, described printed circuit board (PCB) silk-screen comprises lamellar body 1 with pad, on 1 four jiaos of lamellar bodies, is provided with fixing hole 10, and the fixed body 22 of pin 2 is installed in fixing hole 10, in order to guarantee the strong bonded of pin and lamellar body, the connecting portion 21 of pin 2 adopts sticking double faced adhesive tape on lamellar body 1.Pin 2 is positioned at four jiaos of lamellar bodies, for printed circuit board (PCB) to be printed is propped and fixed.If printed circuit board (PCB) is larger, only fix four jiaos, printed circuit board (PCB) medium position can cave in, and the uneven printing effect that affects of plate face, therefore arranges top nail, for supplemental support printed circuit board (PCB) in other position of lamellar body 1.The connecting portion 31 of top nail adopts sticking double faced adhesive tape on lamellar body 1,32 pairs of printed circuit board (PCB) supplemental support of supporter.In order not affect the operation of performance and the subsequent handling of printed circuit board (PCB), the corresponding position that general top nail is arranged on that lamellar body 1 need be windowed with printed circuit board (PCB), moulding, V-CUT etc. are located.
When pad of the present invention is used, printed circuit board (PCB) can be erected, be convenient to printed circuit board (PCB) and simultaneously finish printing end blocking printing another side, after printed on both sides, two sides can disposablely complete pre-baked.On the other hand, printed circuit board (PCB) is erected, its upper and lower circulation of air is better, during ink for screen printing, is convenient to ink and fully immerses, and particularly for some via holes, whole silk-screen is effective
Those of ordinary skill in the art will be appreciated that, above embodiment is only for the present invention is described, and be not used as limitation of the invention, as long as within the scope of connotation of the present invention, to the variation of the above embodiment, modification, all will drop within the scope of claim of the present invention.
