Embodiment Construction
[0025] The present invention provides a metal-based PCB board without spacing and its cutting method. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0026] The embodiment of the metal-based PCB board without spacing of the present invention, such as figure 2 with image 3 As shown, it includes a metal-based PCB and a plurality of finished units 100 formed on the metal-based PCB. The upper surface of the metal-based PCB is a circuit surface 120, and the lower surface is a metal-based surface 130. There is no spacing at the joint, that is, two adjacent finished units 100 are closely arranged, and the unit spacing 110 between adjacent finished units 100 is removed. This structure reduces process waste an...

The invention discloses a metal PCB (Printed Circuit Board) space-free jointed board and a cutting method thereof. The metal PCB space-free jointed board comprises a metal PCB and a plurality of finished product units which are formed on the metal PCB, the upper surface of the metal PCB is a circuit surface, the lower surface of the metal PCB is a metal base surface, and the connection positions of the finished product units have no spaces. According to the invention, by adopting the method that the metal PCB is cut simultaneously through an upper V-cut cutter and a lower V-cut cutter, the undesirable phenomena that during the board punching and shaping production processes, when the spaces among the units are reduced, the flashing, the board breaking and the like are produced can be avoided, the scrap edges produced in the production process are reduced, the cost of the board is reduced, and the utilization rate of the board is improved.
Description
technical field [0001] The invention relates to the field of metal-based PCB boards, in particular to a metal-based PCB board without spacing and a cutting method thereof. Background technique [0002] At present, the jigsaw puzzle of metal-based PCB in the production process is as follows: figure 1 As shown, a certain unit spacing 110 needs to be given between two adjacent finished units 100 as a buffer area when the finished units 100 are divided into panels during the forming process. The unit spacing 110 is indispensable in punching and forming, and the absence of the unit spacing 110 will cause undesired phenomena such as edging and plate cracks during the production process of punching and forming. [0003] In the production of metal-based PCBs, as the price of metal-based substrates continues to rise, the cost of boards accounts for an increasing proportion of the total cost. The cell pitch 110 is currently unavoidable production process waste, which causes great wa...
