The Processing Methods of Printed Board Shape

• Milling the Shape

  Utilize a CNC milling machine and provide milling shape data and pipe hole files. Use a 3mm diameter milling cutter due to limited spacing. Drill pipe holes on the milling bed, secure the printed board, and mill the shape based on the data.

• Punching the Shape

  Requires a mold and aligning pipe position nails with the board’s holes using a φ3.0mm hole for pipe positions.

• Opening “V” Grooves

  Segment the board with a “V” groove cutter along specified lines.

• Drilling Shapes

  Use a drill press to create holes along the outline, with “V” grooves and drill shapes as auxiliary methods.

The Choice of Shape Processing Method

Choose the method based on customer requirements and batch size, with milling shapes typically preferred. Pay attention to cutting point selection, cutting tool direction, and cutting shape orientation. Special care is needed for inner grooves with convex angles and rounded corners to prevent deformation.

Effectiveness of Auxiliary Shape Processing Means

Opening “V” grooves is a common method that enhances efficiency, especially for smaller board units. Larger panel batches benefit from this method, while drilling profiles overcome equipment limitations. Stamp holes between unit panels facilitate varied board assembly.

Importance of Tube Hole Placement

Tube holes are crucial for efficiency in punching and milling methods. Consult technical experts for optimal mold utilization and consider hole size and placement for optimal shape processing. As PCB design evolves, shape processing technology advances, benefiting many manufacturers.
