PCB depaneling method and Routing separator introduction
Author : Alan Zhang
The depaneling method of PCB is divided into three categories, class A: manual depaneling; class B: line (V-cut separator); class C: curve (Routing separator). The distinguishing method lies on the board connected way, need to adopt what kind of category to depaneling?

PCB depaneling approach:

  • ◆ Class A: manual depaneling
  • Advantage: Fast efficiency
  • Disadvantages: manual depaneling may cause damage to the stress-sensitive components.
  • {Cutting stress is large (800 ~ 1800μS)}
  • ◆ Class B: straight line (V-cutseparator): Also divided in two kind, blade moving and board moving.
  • Blade moving: suitable for multiple boards, hollowed out in the middle of PCB depaneling operations.
  • Board moving: suitable for straight line V-cut, there is no hollowing PCB depaneling operation.
  • Advantages: lower cost, simple operation, and fast speed.
  • Disadvantages: can be straight-line sub-board, and will leave a little rough edge.
  • {Cutting stress is medium (500 ~ 750μS)}.
  • ◆ Class C: (Routing separator): the middle of the PCB board adopted the board connected with stamp hole or
  • support point, through writing of program design, use iron knife to segment PCB board.
  • Advantages: proceed any shape of depaneling. The stress is very small, no edges at the cutting edges.
  • {Cutting stress small (100 ~ 200μS)}.

Introduction to Routing separator

  • 1. PCB placed on the platform of the machine, use the dedicated thimble to fix on the screw hole of PCB, make
  • it positioned (if multiple linking board need to create a dedicated vehicle, then operate).
  • 2. Using high-resolution color CCD camera lens to write the path to be cut.
  • 3. Finally, use of high-precision high-speed servo motor, carry with a dextrorotation form tungsten
  • steel milling cutter to segment PCB board.
Summary Features: It can cut to irregular shape, produced the minimum stress, dual-platform increase production efficiency, so PSI bought and set up the "Routing separator" in order to achieve the standards and quality of the customer. The production line also continued the education training to workers in order to write programs and assignments, now already can import on-line work. And get the original technology, manpower counseling, let us encounter any situation can immediately communicate, handle and solve in the production process, and wewill not let the production action interrupted.
With the Routing separator and the original V-cut separator ( one blade moving; two board moving machine ), enough to deal with all the current PCB board, let the problems produced by "stress damage" bottom out.
