Embodiment 1
[0019] Using the method for forming the sharp corner area of the circuit board to form the circuit board with the tip width of the sharp corner area of 0.6 mm, the steps are as follows:
[0020] Step 1, in the drilling process before forming, a through hole with a diameter of 0.6 mm is provided at the tip of each circuit board to be processed at the sharp corner;
[0021] Step 2, take three pieces of circuit boards to be processed and fix them on the working position of the CNC molding equipment;
[0022] Step 3, when CNC forming, use a milling cutter with a diameter of 0.6mm, and take the center of the through hole as the cutting point of the milling cutter.
[0023] After forming the sharp corner area of the circuit board, replace the large-diameter milling cutter and increase the length of the large-diameter milling cutter to form the area other than the sharp corner area. Because the risk of breaking the large-diameter milling cutter is greatly reduced, you can incre...
Embodiment 2
[0025] Using this method for forming the sharp corner area of the circuit board to form a circuit board with a tip width of 0.7mm in the sharp corner area includes the following steps:
[0026] Step 1. In the drilling process before forming, three through holes are arranged at the tip of the sharp corner area of each circuit board to be processed, and the three through holes are arranged linearly along the ray direction of the apex of the tip. The three through holes The holes intersect, and the ray direction along the apex of the sharp corner area gradually increases, and the diameters of the three through holes are 0.6mm, 0.7mm, and 0.8mm;
[0027] Step 2, take four pieces of circuit boards to be processed and fix them on the working position of the CNC molding equipment;
[0028] Step 3: Use a milling cutter with the same diameter as the through hole closest to the apex of the tip, that is, use a milling cutter with a diameter of 0.6mm, and take the center of the throug...
Embodiment 3
[0032] Using this method for forming the sharp corner area of the circuit board to form a circuit board with a tip width of 1 mm in the sharp corner area includes the following steps:
[0033] Step 1, in the drilling process before forming, set four through holes at the tip of the sharp corner area of each circuit board to be processed, and the four through holes are arranged linearly along the center line of the sharp corner area, and the four through holes Intersect, and gradually increase along the ray direction of the apex of the sharp corner area, the diameters of the four through holes are 1mm, 1.2mm, 1.4mm, 1.6mm;
[0034] Step 2, take five pieces of circuit boards to be processed and fix them on the working position of the CNC molding equipment;
[0035] Step 3: Use a milling cutter with the same diameter as the through hole closest to the apex of the tip, that is, use a milling cutter with a diameter of 1mm, and take the center of the through hole closest to the a...
