Abstract
The invention relates to a printing device for a printed circuit board (PCB). The printing device comprises a silk screening bench, wherein the silk screening bench is provided with a bench top; the bench top is provided with positioning nails; the positioning nails are distributed into a rectangle; and copper nails are arranged in the rectangular area of the positioning nails. According to the printing device, the positioning nails are arranged on the silk screening bench, and the copper nails are distributed in the area formed by the positioning nails, and thus, a nail bed is formed on the silk screening bench; therefore, one surface of the PCB is prevented from contacting with the silk screening bench in the process of printing the other surface of the PCB, solder masks on both surfaces are printed once, the board baking time is greatly shortened, and the machining efficiency is improved.
Description
Technical field
The present invention relates to a kind of printed circuit board printing equipment.
Background technology
Multifunction, miniaturization progress along with e-machine need the burden more function on the circuit board, therefore can't carry down at the single face circuit, so stride forward towards double sided wired direction.What at present the mutual connection of double-side pattern often adopted is the logical method of plating, and it utilizes the mode of the electroplates in hole and etching Copper Foil, the local useless Copper Foil of substrate surface is removed, thus the substrate surface of the no conductor of formation.
Pcb board all is printed on one side when printing resistance weldering and literal and accomplishes.Because therefore problems such as photosensitive solder resist printing ink roasting time in baking box has been grown, and can cause and bake extremely, and it is unclean to develop use double-side printer to enhance productivity, and reduce roasting plate number of times.In order to prevent the roasting dead and unclean problem of developing, conventional way: first clipsheet is dried second on back seal; But the for the first time roasting plate time can not surpass 25 minutes, and this way also can be produced, but has following shortcoming: when printing second, might be bonded at the silk-screen table top, fall oil, efficient is low, quality does not have guarantee.
Summary of the invention
The technical problem that the present invention will solve is: a kind of printed circuit board printing equipment is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of printed circuit board printing equipment; Comprise the silk-screen platform, described silk-screen platform is provided with table top, has the location nail on the described table top; Rectangular distribution is followed closely in described location, is provided with fastener in the rectangular area of location nail.Described fastener is a convex.Described fastener is equally distributed a plurality of.
The invention has the beneficial effects as follows, solved the defective that exists in the background technology, the present invention is through being provided with the location nail at the silk-screen platform; And in location nail institute forms the zone distribution fastener, follow closely bed thereby on the silk-screen platform, form one, thus in printing second pcb board process; Avoid another side to contact with the silk-screen platform; Thereby realized disposable printed two sides resistance weldering, the roasting plate time has been shortened greatly, and improve working (machining) efficiency.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the structural representation of the preferred embodiments of the present invention.
The specific embodiment
Combine accompanying drawing and preferred embodiment that the present invention is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
A kind of pcb board double-side printer as shown in Figure 1, this device are mainly used in the resistance weldering of pcb board two sides, when carrying out printed on both sides, prevent lower plate and the adhesion of silk-screen platform and the lower plate that produces is bonded at the silk-screen table top and falls oily problem.Wherein said pcb board double-side printer mainly includes a silk-screen platform 1, this silk-screen platform 1 is provided with silk-screen table top 2; Be distributed with location nail 4 on the said silk-screen table top 2; The location nail 4 here is at least more than three and (mainly utilizes the mode of three-point fix), and these location nails 4 are leg-of-mutton three summits, and its zone that forms is a triangle; And on this leg-of-mutton limit and inside also be distributed with a plurality of fasteners 3, formed a zonal nail bed.
In addition, the location nail 4 that distributes on the silk-screen table top 2 also can be four, can form a rectangular area through these location nails 4, and in this rectangular area, also be distributed with a plurality of fasteners 3, thereby form the nail bed of a rectangular area.Wherein above-mentioned location nail can be with four limit bed hedgehopping 8-10MM of pcb board, then use fastener at the mid portion of plate, and when printed one side, second on the seal that turns over gets final product.
What describe in the above specification is the specific embodiment of the present invention; Various not illustrating constitutes restriction to flesh and blood of the present invention; Under the those of ordinary skill of technical field after having read specification can to before the described specific embodiment make an amendment or be out of shape, and do not deviate from essence of an invention and scope.
