Embodiment Construction

[0028] A CNC gong plate production method without NPTH hole positioning of the present invention, in order to make the purpose, technical solution and advantages of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] Among them, the gong board is to use the gong machine to output the specified jigsaw pattern on the circuit board through the milling cutter according to the pre-programmed program. Advantages: According to the program, various shapes of jigsaw patterns can be produced on the board, several boards can be overlapped and processed at the same time, the molding size of the board is high, and the interface of the board is smooth.

[0030] Such as figure 1 As shown, a CNC gong board production meth...

Abstract

The invention discloses a CNC (Computer Numerical Control) board splitting production method without NPTH (Non Plating Through Hole) hole positioning, which is used in single PCS (pieces) shipment production in the manufacturing process of printed circuit boards, and because secondary forming is adopted, when CNC board splitting is carried out on a single PCS board, at least four groove angles of NPTH grooves distributed on the single PCS board are selected as forming positioning holes for board splitting, and remained reserved connecting positions of appointed areas are split. At least four NPTH groove angles in the PCS board are selected for positioning, PIN holes are arranged in the position tangential to the groove angles, and the PIN holes need to be distributed at four edges of the PCS board to the greatest extent so as to ensure that the PCS board does not move in four directions. The diameter of a selected pin is 0.05mm smaller than the diameter of a PIN hole drilling tool. Compared with a PTH (Plated Through Hole) hole positioning mode, the method disclosed by the invention makes a finished product do not have the problems of hole wall pull break, pad abrasion, poor solderability, hole copper fracture and the like. Compared with a gummed paper sticking positioning mode, the method disclosed by the invention makes the finished product have a more stable size and have no off tolerance, and the board splitting efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of CNC gong boards, in particular to a CNC gong board method for positioning without NPTH holes in single PCS shipments during the production process of printed circuit boards. Background technique [0002] CNC, also known as computer gong or numerical control machine tool, is the abbreviation of computer numerical control machine tool (Computer numerical control), which is an automatic machine tool controlled by a program. The control system can logically process the program specified by the control code or other symbolic instructions, and decode it through the computer, so that the machine tool can perform the specified action, and the blank can be processed into a semi-finished product by cutting the tool. [0003] The printed circuit board (PCB board) is processed into some conductive patterns on an insulating board of a certain size, and has holes (such as component connection holes, fastening holes, me...
