Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiments of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

The description in the present application relating to "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying any relative importance or implicit indication of the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.

An embodiment of the utility model provides a printing nail bed, as shown in fig. 1, include: PU board 20, PCB board 10 and several support parts; the size of the PU plate 20 is larger than or equal to that of the PCB 10, and the PU plate 20 is made of transparent material; the supporting portion is detachably connected to an end surface of the PU board 20, corresponds to the inactive area of the PCB board 10, and is used for bearing the PCB board 10.

The PU plate 20 is attached to the PCB 10, and the PU plate 20 is made of transparent or semitransparent material, such as acrylic rubber plate. The pattern on the PCB 10 can be seen through the PU board 20, and the PCB 10 includes an invalid area, which is a blank area without electronic components on the PCB 10. According to the invalid area of the PCB 10, a position corresponding to the invalid area of the PCB 10 is found on the PU plate 20, a supporting part is arranged on the corresponding position, and the supporting part is detachably connected on one end face of the PU plate 20. In the solder mask double-sided printing, the printing of the first surface of the PCB 10 is finished, and the PCB 10 can be placed on a nail bed for avoiding the ink on the first surface from being stained on a printing table. Wherein first face contact nail bed supports PCB board 10 with the second face of printing PCB board 10, and the supporting part supports PCB board 10, and wherein, the dead zone that the strong point is PCB board 10 is, under the condition of not damaging the electronic component, can effectively avoid the printing ink of first face to be stained with on the printing bench.

PU board 20 is transparent material, and the figure of PCB board 10 is seen to permeable PU board 20, is convenient for find the position that PU board 20 and PCB board 10 invalid area correspond, sets up the supporting part in the position that PU board 20 and invalid area correspond to support PCB board 10.
